Machinery for Pasting or Cementing Strips of Paper or other
Material on Paste-board Boxes and other Objects.
I, GABRIEL PATUREAU, of 14 Rue Danton, Levallois-Perret, Seine, France,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to new machinery for effecting automatically the pasting or
cementing of strips or bands of paper or other material round paste-board boxes
and such like hollow objects, which operation has hitherto been done by hand.
For this purpose a continuous strip or band of paper or other material is led from
a roll over the periphery of a pasting wheel which revolves in a trough of paste
and thus applies paste to one side of the paper band.
.
By preference I employ two such paper bands with their paste wheels, and after
each band has been pasted they both are led together so that the pasted side of one
strip is applied to the unpasted side of the other. The double band thus produced
is then led through squeezing rollers which feed it forward with a step-by-step
motion imparted thereto by a crank arm actuated by the driving shaft and con-
nected by ratchet gear with the roller spindle, the crank arm being made to receive
a to and fro motion through levers and connecting rods from a cam on the driving
shaft.
One pair of nipping rollers tend to feed the paper rather faster forward than
the preceding pair, so as to keep the paper band tightly stretched. Between two
pairs of such rollers is situated a shearing instrument carried by a slide, which,
after a certain length of the band has been fed forward is moved forward and cuts
off such length. The part of the band behind the cut is, at the time of the cut,
held by a pressing arm so as to prevent it from moving back, and the cut portion,
which is seized by rollers in a sliding carriage, is moved forward by the latter into
the position for being applied to the paste-board box. The boxes, which may be
either circular, oval, or any other configuration, are fed through a hopper between
fingers carried by a slide and situated opposite the overhanging head of a horizontal
revolving mandril, so that the fingers, on being slid forward, carry the box up to
the mandril head, whereupon a disc situated centrally between the fingers behind
the box is pushed forward by a cam action so as to push the box on to the mandril
head. This mandril head has the same configuration as the interior of the box,
and it is split into several spring-segments in a longitudinal direction, such
segments being capable of being sprung outwards, so that after the box has been
placed upon it, with a loose fit, the mandril is expanded so as to fit tightly against
the box and thus carry it round with it. Such expanding of the mandril is effected
by a coned centre picce having a central stem passing through the mandril and
acted upon firstly by a spring which tends to draw the centre piece inwards and
cause it, in pressing against the sides of the corresponding hole in the mandril
head, to force the segments outwards as described, and secondly the stem is acted
on periodically in the contrary direction by a lever acted upon by a cam on the
driving shaft, so as to cause the centre piece to protrude from the face of the
mandril head and thus allow its segments to spring inwards again, while at the same
time the protruded centre piece will effect the pushing off of the box from the
mandril head again.
In order to prevent too great a strain from being exerted on the bottom of the
box by the centre piece, in case the box should stick, there is provided an arm
above the mandril, which, by a cam action, is caused to move forward at the time
when the box is being removed, and to bear with a pointed beak on its front end
against the edge of the box and thus assist in pushing it off.

page_text: Below the mandril head, in the same plane with its end face, is a roller carried
by a lever acted on by a cam-motion so as to be first slightly separated from the
periphery of the mandril, in order to allow the end of the before mentioned pasted
paper strip, which is fed forward in line with the mandril at right angles thereto,
to be introduced between the two, after which the roller is moved up against the
mandril, thereby pressing the pasted side of the paper band firmly against the box
on the mandril, and by the rotation of these parts the whole of the strip is then
wound round the box, and is made to adhere thereto both by the pressure of the
said roller and by that of a cylindrical brush carried by an arm, which is suitably
actuated from the driving shaft so as to bring the brush against the side of
the box.
The box having been thus covered, it is thrown off the mandril, as above
described and is led along a shoot to a revolving table having a number of holes
round its periphery corresponding in shape to that of the boxes, one of which is
placed by hand in each of the holes bottom downwards. The paper band is of such
a width that a portion thereof projects up beyond the rim of the box, and this
projecting portion has now to be folded down over the rim of the box, and made to
adhere to the inner side thereof. For effecting this operation the table has a step-
by-step rotary motion imparted to it, whereby the holes containing the boxes are
brought consecutively over a revolving disc attached to a vertical perforated
spindle, in the perforation of which is a closely fitting rod arranged so as to be
raised and lowered in the perforation by a cam action, so that when the box is
brought by the table over the disc with the bottom of the box resting on the latter,
a downward motion of the said rod will produce a partial exhaust beneath the box,
whereby its bottom will be made to adhere closely to the rubber-faced disc, and
consequently to partake of the rotation thereof. At the same time a horizontal
rod is advanced by a cain motion so as to project across the table and to push with
its beak-shaped end against the projecting part of the paper band, thereby causing
it to be bent over inwards over the rim of the box.
Centrally above the disc is arranged a vertically sliding plunger with caoutchouc
periphery, which, at fixed intervals of time, is made to descend by cam action,
being thereby made to enter the box beneath it and consequently to press down-
wards the bent-over portion of the paper band and to cause it to adhere to the
inner surface of the box. The said plunger works within a vertical slide which
also receives a downward motion by a cam action, so as to bear upon the upper edge
of the box, while the plunger is being first forced down into it as described and is
then moved upwards again, out of the box, this being thus held down by the slide
so as to enable the latter operation to be performed, after which the slide rises
again, leaving the finished box free to be removed.
When employing the above described machine to cover boxes that are not
circular, such as oval boxes, the mandril head, which has a corresponding oval or
other shape, requires firstly to remain stationary at the time when box is being
placed thereon in the manner described, and secondly, in revolving, it requires to
be moved transversely in such a manner that its lower part is always presented in
the same horizontal plane to the pressing roller by which the paper band is wound
round the box.
For the first named purpose, the mandril is connected to the gearing by which it
is rotated by means of a friction clutch with spring action, one part of which clutch
is carried by the mandril stem so as to slide thereon, and is connected to the before
mentioned central stem of the coned centre piece of the mandril, so that when the
centre piece is pushed forward as described for allowing the mandril to contract
preparatory to receiving a box, the stem at the same time moves the clutch out of
gear, and consequently the mandril remains stationary.
For the second above named purpose, the head of the mandril which receives the
box, is mounted on a transverse slide carried between guides on the vertical end
face of the other part of the mandril. On the corresponding end of the fixed
cylindrical support within which the mandril rotates is fixed a disc having an

page_text: excentric or cam-shaped periphery, and the said slide has an extension at
each end on which are mounted rollers that bear against the excentric periphery of
the disc, so that as the mandril is made to rotate, the fixed excentric disc causes
the slide together with the mandril head to move transversely relatively to the axis
of the disc, and this motion is so regulated by the shape of the excentric that the
lowest part of the revolving oval mandril is always made to remain in one and the
same horizontal plane.

Machinery for Pasting or Cementing Strips of Paper or other
Material on Paste-board Boxes and other Objects.
I, GABRIEL PATUREAU, of 14 Rue Danton, Levallois-Perret, Seine, France,
Manufacturer, do hereby declare the nature of this invention and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement :-
My invention relates to new machinery for effecting automatically the pasting or
cementing of strips or bands of paper or other material round pasteboard boxes
and such like hollow objects, which operation has hitherto been done by hand.
The said machinery is shewn on the accompanying drawings in which :-
Figure 1 shews a sectional side view of the machine,

Figure 2 a plan,
Figures 4, 5, and 6 side view, vertical section, and sectional plan of apparatus for
feeding the cut paper strip to the box to be covered.

of the box and pasting it on the inside thereof.
Figures 15 and 16 vertical section and end view of a modified form of the
mandril for operating on oval boxes.
This machine is designed to carry out the following operations
1. Preparation and pasting of the paper strip to be applied to the boxes.
2. Forward feed of the paper strip.
3. Cutting the strip in lengths corresponding to the size of the boxes.
4. Feed of the boxes on to the mandril where the paper strip is to be applied.
5. Coiling pasted paper strip on to the box and pressing it thereon by a
revolving brush.
6. Expelling the boxes after pasting, and
7. Turning paper strip over the edge of the box and pasting the same on to the
interior thereof.
By preference employ, for the purposes of my invention, two paper strips
pasted one upon the other, in place of a single strip, and I will describe the
machine arranged in this manner, although it is also applicable with a single strip.
The two paper strips or bands A and B are coiled up in rolls C and D carried
by pivots on the framing, and are led thence over guide rollers 1, 2, to discs a and b
which are partly immersed in paste troughs 5 and 6, so that the bands in passing
over them cause them to revolve and thereby to carry the paste on to the side of
the strip which is in contact with the disc.

page_text: From the disc a, the paper strip A is led over roller 3 over which strip B is also
led, the latter being made to present its pasted side outwards, so that as A passes
in contact with it, also with its pasted side outwards, the two strips become
cemented together, forming a combined strip A¹ which passes over roller 4 into the
machine with its pasted side upwards.
From the roller 4 the paper strip passes over guide rollers a between feed rollers &
which receive an intermittent step by step motion by toothed gearing A actuated
by crank arm 7 to which a to and fro motion is imparted by rod 8, lever 9 and
rod 10 actuated by a cam 11 on the driving shaft U of the machine, the end of the
rod 10 being pivotted to a rocking support. The to and fro motion of the arm 7
is communicated in one direction only, by means of any suitable pawl and ratchet
mechanism 12, Figure 2, so that at certain intervals of time, determined by the to
and fro movement of 7, the feed rollers receive a partial rotation such as to
draw forward a length of paper strip corresponding to that required for pasting on
the boxes.
From the feed rollers the paper strip passes over a series of rollers a a to a
pair of pressing rollers actuated by an endless cord and pulley from the
rollers 9.
From the rollers the paper strip passes on to a table ẞ, where it is pressed
upon by a roller y and it then passes between two other feed rollers hd mounted
upon a sliding carriage J which is made alternately to move from the table ẞ
towards the mandril G and back again. This carriage together with its actuating
mechanism is shewn more clearly in the detached views at Figures 4, 5 and 6. It
is formed with an elbow frame carrying the pressing roller and the nipping
rollers d; of the latter the upper one d is mounted on arms J which are pivotted
to J and have downward extensions Ja the lower ends of which have small rollers k
resting on a bar K. As the carriage J is moved back from the mandril G, in a
manner to be presently described, the rear ends of the bars K are raised up by
lever arms 49 actuated by lever 50 with roller 51 resting on a cam on the shaft U,
to which arms the bars are hinge jointed.
The rollers in running up the inclines thus formed by the bars cause the
arms J to turn upward on their pivots against the downward pressure of a
spring J and thereby raise the roller d from off the roller h.
The carriage J carries a table c over which the paper strip passes, and which
has a gap through which the rollers hd come in contact. As the carriage recedes
with the roller d raised as described, the paper strip which is being fed forward
by the roller passes on to the table c and when the carriage has completed its
stroke the lever arm 49 causes the bar K to drop again, thereby allowing arm J2
and roller d to descend, so that d now nips the strip of paper between it and
roller. The carriage J then moves forward again, carrying the paper with it,
the front end of the latter being made to lie on the roller f. This roller is carried
by an arm J' pivotted to the carriage J and resting on a stop on the latter in such
a position that the roller together with the paper upon it can pass freely forward
underneath the mandril G. When the carriage has arrived in this position a
shearing device H to be presently described cuts through the paper at a point close
to the end of the table ẞ thus leaving a length of strip on the carriage, of a length
corresponding to the circumference of the box to be covered the arm J¹ is then
pushed up by a rod f' acted upon by a cam on the driving shaft U, so as to press
roller against the mandril G, and thereby pressing the pasted side of the paper
strip upon the box which has been previously placed upon the mandril as will be
presently described.
The to and fro motion of the carriage J for the above purpose is imparted as
follows :―
The carriage has on its undersidé a toothed rack J, with which gears a toothed
segment arm having its pivot at r² and acted upon by a cam 52 through roller j
rod s crank arm 46 on an axis 47 carrying a second crank arm 48 connected by a
rod 63 to the segment arm. Thus by the rotation of the cam 52 the segment

page_text: arm is first made to move the carriage J towards the table ẞ so as to receive the
strip of paper, and is then moved towards the mandril G.
The shearing device H is shewn at Figs. 7 and 8. A sliding carriage p receives
an advancing and receding motion from a cam drum I on the driving shaft by
means of a double ended lever Q; it carries a pair of shears H the lower jaw of
which is fixed to the carriage in such a position that as the latter advances, the
jaw passes underneath the paper strip at a point just beyond the end of the table ẞ.
The upper jaw is pivotted to the carriage and its axis is acted upon by a spring 55
so as to keep the jaw in the open position shewn at Fig. 7. The axis of the jaw
has a tail 54 at its end, which, when the carriage p is advanced into the shearing
position, is brought up against an arm V on a spindle 53 carried by the framing
and having at its other end an arm O with a roller bearing upon the face cain 1,
so that by the rotation of the latter, the arm V is made to act upon 54 so as to
cause the shears to shear the paper strip. At the moment of shearing, the rear
part of the paper strip is nipped upon the table ẞ by a roller 15 on an arm 12 so as
to hold it stationary until the carriage J has begun to move back again to receive
another length. This arm 12 is pivotted to a standard and has a tail the end 13 of
which is recessed and engages with a roller 14 on the carriage J.
carriage is in the backward position this roller in bearing upon the tail of the arm,
depresses it so as to keep the roller 15 off the table ẞ, but when the carriage
arrives at the end of its forward motion the roller passing onto the recessed part 13
of the tail allows the arm 12 with its roller 15 to drop by its greater weight and
press the paper upon the table as described.
When the
For placing the boxes to be covered with paper upon the mandril G, the
following mechanism is employed.
A sliding carriage F receives a to and fro movement from the cam drum i on the
shaft U by an arm F¹ carrying a roller engaging with the cam groove. The
carringe carries upon a cylindrical projection F a rotatable cylinder 9 having a
cam groove 59 into which takes a roller 57 carried by a fixed frame 58, so that by
the to and fro motion of the carriage F the cylinder is caused by cam groove 59
and roller 57 to turn to and fro through a certain angle.
To the front of the carriage F is fixed a plate o in slots in which slide two
horizontal curved jaws and above these jaws the plate carries a shoot E into the
upper end of which are placed by hand the pasteboard boxes to be covered. The
jaws carry at the back of the plate rollers situated in the eccentric slots of ears n,
carried by the cylinder 9. The result of this arrangement will be that as the
carriage recedes from the mandrils G, the partial rotation of 9 and n causes the
jaws to move apart, thereby allowing one of the boxes to drop between them
from E, at the extreme end of such backward motion, whereupon the carriage will
be immediately moved forward again, causing the jaws to advance and hold the box
between them.
Centrally between the jaws at the back of the box held thereby is a disc 16
fixed on a stem 17 passing back through the cylinder F2 of carriage F and having
its end fixed to another carriage 18, which receives a to and fro movement from the
cam drum 19 on shaft U. This motion is so proportioned to that of a carriage F,
that as this advances towards the mandril G, the disc 16 is made to advance at the
same speed, but when F has arrived at the end of its travel, just in front of the
mandril, the disc 16 continues to be moved forward so as to push the box from
between the jaws and on to the mandril head, the box having its opeu end
presented towards the latter. On the carriage F now receding again, the
carriage 18 is held stationary for a certain time, thereby causing the disc 16 to
hold the box against the mandril during the time the paper strip is being coiled
upon the former. The carriage 18 then recedes again, bringing the disc 16
into its original position between the jaws before these have opened out sufficiently
for a fresh box to drop between them.
The construction and action of the mandril G will be understood on reference to
Figs. 2 and 9. The mandril head G is fixed on a cylindrical body G¹ rotatable in

page_text: a fixed bearing G² and carrying at its back end a toothed pinion t by which it
receives rotary motion from the shaft U through the spur wheel T. The mandril
head G is split longitudinally so as to be formed into a number of spring segments,
and it has a central coned opening, into which fits a coned disc L having a stem I
passing through G₁ and having at its rear end a screwed collar L' against which
bears a spring R. which tends to press the stem and disc backwards. When in this
backward position, the disc L slightly expands the spring segments of the head G.
At the rear end of the mandril is a double ended lever O the lower end of which
is acted upon by a cam M on the shaft. U while the upper end has an adjustable
pin which bears against the end of the stem L', so that at certain intervals of time
the lever is caused by cam M to first push the stem and disc slightly outwards,
without protruding the latter beyond the mandril, so that this can contract in order
to allow of the ready placing thereon of a box, after which the lever recedes so as
to allow the disc L to be pushed backwards to expand the mandril and thus cause
it to hold the box tightly in order to carry it round with it for having the paper
strip coiled upon it, and lastly the lever is made to move the stem and disc
considerably forward, so as to push the box off the mandril after which the disc is
brought back by the spring R again.
Assuming a box to have been placed upon the rotating mandril head Gas
described, and that the carriage J has at the same time moved forward so as
to bring the roller with the end of the pasted paper strip lying upon it,
immediately beneath the mandril head, then on the roller f being pressed
upward by the rod fit will press the pasted side of the paper strip against
the box on the mandril, and consequently, as the latter revolves, the paper
strip will be wound upon it. While this is being effected a revolving brush 20,
shewn at Figures 2 and 13, carried by an arm 21 and driven by cords 75 and 76
and pullies 77 78 and 79 from the mandril body G¹, is brought up against the
paper strip on the box, so as to press on the outer projecting edge of the strip
and thus cause it to be bent over on to the bottom of the box and to adhere
firmly to the latter, for which purpose the brush arm 21 is carried by a
spindle 80 having at its lower end a toothed pinion 22 gearing with a toothed
sector 49 pivoted to a fixed bracket on the framing, and having an
bearing with a roller against a cam 23, which at the required moment turns
the sector 49 and pinion 22 so as first to bring the brush 20 in contact with
the box while the paper strip is being wound thereon, and then to move it
away again, so as to allow the box to be pushed off the mandril as described.
In order to assist in such throwing off of the box in case it should stick on
the mandril, a lever 24, Figure 3 mounted on an arm 27 on the mandril
bracket G is connected by elbow lever 26. and rod 25 to an eye on the end
of the before described lever O, so that as this moves forward for protruding
the disc L it at the same time causes the beak-like end of the lever 24 to push
against the rear edge of the box on the mandril.
arm 21
The paper strip is of such a width, that, when secured on the box as described,
a portion thereof projects beyond the edge of the box for the purpose of being
turned over such edge and pasted against the inner surface. For effecting this
operation, the box falls from the mandril G along a shoot indicated in dotted lines
at 51, Figure 1, on to a revolving circular table 27, Figures 1, 2 3 and 14. This
table is mounted on a fixed spindle 52¹ and receives a step by step rotary motion
from a cam 28 on a shaft 53' driven from the main shaft U by a pulley and
strap. 54¹
The cam 28 acts on the arm 29 of a lever 30, pivotted at 55 and having a slot
through which passes the spindle 52', and carrying at its end a spring pawl 56¹
which gears with the ratchet wheel 57 on the underside of table 27, so that at each
revolution of the shaft 53', the cam 28 causes the lever 30 to move the table round
to the extent of one tooth of the ratchet. In order to insure the correct movement
of the table at each stroke it carries a ratchet ring with which gears a spring stop
on the framing (not shown). At the circumference of the table 27 are a number

page_text: of circular holes w, of such size that the boxes descending from the mandril G, can
be placed freely therein by hand. so as to rest with their bottoms upon an annular
rail 58, fixed on the framing. Thus as the table travels round by a step by step
motion, it carries the boxes round with it, until they arrive over a disc 33, situated
in a gap of the rail 58, at the same level as the latter; this disc is faced with
caoutchouc and is connected to a tubular stem 591 within which is a rod 60 carried
by a slide 61 sliding on a fixed stem 31 and actuated by a lever 60' pivotted to the
framing and having a roller 63 bearing on the periphery of a cam 32 on the
shaft 53' which cam is so formed that at each rotation it causes the lever to drop a
certain distance by its weight, and then to rise again so that at each rotation of
this shaft the lever 60¹ is made to move the rod 60 rapidly downwards to a certain
extent immediately after one of the boxes has been brought upon the disc 33,
thereby creating a slight vacuum below the box, which causes this to adhere to the
rubber faced disc 33. On the stem of the latter is a coned friction disc 35 gearing
with a friction wheel 34 on shaft 53', so that the stem 59, disc 33 and the box upon
the latter receive a rotary motion by this means. Above the disc 33 is a slide 41,
carried in a guide on a bracket 65¹ fixed to the framing, and within the slide is a
sliding stem, 66¹ terminating at its lower end in a piston 42.
The slide 41 has two lateral studs projecting through slots in the guide as at
Figure 1 and connected to elbow levers 40, pivotted to bracket 65' and actuated
by a cam 39 on shaft 53', so that at each revolution of the latter the slide receives
an up and down movement. To the stem 66¹ is connected an elbow lever 43, also
pivotted to bracket 65' and actuated by a cam 45 on shaft 53. Passing diametrically
across the table 27 is a rod 38 the one end of which is connected to a slide 37,
having an arm passing through a slot in the frame, and engaging with a cam 36 on
shaft 53', by which the slide and rod receive a to and fro motion at each revolution
of the shaft. The rod 38 is guided in such motion by sliding with a slotted middle
part upon the projecting end of the spindle 52¹ of the table. The other end of the
rod 38 is formed with a curved beak, as shewn. The operation of these parts is as
follows:-
A box having been brought upon the disc 33 and put into rotation thereby as
described, the rod 38 is made to advance and, by means of its beak, to bend the
projecting edge of the paper inwards over the edge of the box after which the rod
retires again.
'
The slide 41 and piston 42 are then made simultaneously to descend so as to
bring the bottom surface of the slide upon the edge of the box, while the piston
passes into the box, thereby bending the edge of the paper strip downwards into
the box and causing it to adhere with its adhesive side against the inner surface of
the latter. The periphery of the piston is for this purpose made of caoutchouc so
as to operate with a more or less elastic pressure, or a thin diaphragm of caoutchouc
may be stretched over the underside of the piston and attached to the edge of the
slide's under face, so that as the piston is made to descend into the box it will
stretch the diaphragm to a corresponding extent and press it against the inner
surface of the box. This having been accomplished, the piston is moved upwards
out of the box by its lever and cam, while the slide is momentarily held down upon
the edge of the box by its lever and cam, in order to prevent the box from moving
up with the piston, and when the latter is clear of the box, the slide also rises.
The rod 60 having meanwhile been moved upward in the tubular stem 59, the box-
is no longer held by suction on the disc 33, and consequently, upon the table 27
now being moved round one step, the finished box is carried away from the disc and
falls down out of the hole w through a gap in the rail 58, while at the same time a
fresh box is brought upon the disc 33, and the above described operation is.
repeated.
Although I have described the machine as operating upon cylindrical boxes, yet
it may also be adapted to operate upon boxes of other shapes, thus Figures 15.
and 16 shew to an enlarged scale respectively a longitudinal section and end view
of a modified construction of the mandril G suited for operating on oval boxes. In

page_text: this case it is necessary that the mandril in rotating shall always present its lowest
edge in one and the same plane, so as to always remain in contact with the pressing
roller, and also, that it shall remain stationary in a certain position when the box
is being placed upon it by the disc 16.
For these purposes the mandril is constructed and operated as follows:-
The mandril head G, which is of oval shape, is not fixed to the body G', but is
capable of sliding transversely upon the front face thereof, by means of a plate v
formed in one therewith sliding between dovetail guides formed on a plate 71 fixed
to G. The plate vis connected by a pin v to an ear on a ring 72 which carries
in recesses small rollers 73 that run round upon a ring 74 fixed in an adjustable
manner by bolts to slotted lugs G' on the bracket G' of the mandril. From
this arrangement it will be seen that if the ring 74 be fixed more or less eccen-
trically to the axis of the mandril, this, in revolving and thereby causing plate
to draw ring 72 round on 74, will effect a lateral shifting of the plate v and
mandril head G between the guides to an extent corresponding to the eccentricity
of. 74, and this eccentricity is capable of being so adjusted relatively to the
proportions of the major and minor axis of the mandril head that the part of the
Tatter which for the time being is lowermost will always be situated in one and
the same horizontal plane as indicated by the dotted lines.
For effecting the temporary.stoppage of the mandril's rotation when the box
requires to be placed thereon, the mandril body G is connected to its pinion t by
means of a conical friction clutch, of which the part 65 is formed in one with the
pinion t, while the part u is attached to arms 67 projecting from the spindle L' of
the coned disc L.
A spring 64 in the bracket G2 tends always to press the part u in with
gear
the part 65 in which case the mandril G G will be carried round by the
pinion t, but when the lever O, acted upon by the cam M as before described
presses the spindle L' inwards so as to relieve the mandril head of the pressure
of the coned disc L, preparatory to receiving a box, the part u of the clutch
will at the same time be drawn back out of gear with 65 and consequently the
mandril will remain stationary until by the backward motion of lever Othe
spindle L' is pressed back by its spring R and thereby puts clutch u in gear
with 65 again.
To insure the exact proper position of the mandril head G when it is brought to
a standstill for receiving a box, the clutch u has a notch 66 into which catches a
spring bolt 69 on the bearing G when the mandril is in the correct position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a machine for pasting or cementing paper or other material upon boxes,
the use of a revolving expanding mandril upon which the boxes are placed for
having the paper pasted thereon, such mandril being formed in sections which are
sprung open for holding the box by a conical plug acted upon a cam, substantially
as described.
2. In combination with a mandril such as is referred to in the preceding claim,
the use of appliances whereby the box is pushed off the mandril by the central
plug and by an external pusher acting on the edge of the box when the paper has
been pushed thereon, substantially as described.

apparatus referred to in the preceding claims, the use of a carriage for automatically
seizing the length of paper and conveying the same to the box on the mandril,
substantially as described.
6. The use in combination with the carriage referred to in the preceding claim,
of a pressing lever with roller which is made to press upon the paper band at the
moment when a length is cut therefrom so as to prevent the same from moving
backward when the cut has been effected, substantially as described.
7. The combination with the mechanisms referred to in the preceding claims, of
feeding mechanism for feeding forward the gummed or pasted paper band inter-
mittently to the carriage and cutting apparatus, the extent of each forward feed
being exactly equal to the circumference of the box to be covered, substantially as
described.
8. In combination with the mandril carrying the box to be covered, the use of a
revolving brush carried by an arm which is suitably actuated so as to bring the
brush in contact with the box in order to turn the lower edge of the paper strip
over the bottom of the box, as this rotates, and then to remove the brush from the
box to allow the latter to be removed from the mandril, substantially as described.
9. In combination with the mechanisms referred to in the preceding claims, the
use of two, or more pasting rollers dipping into paste reservoirs, over which two or
more bands of paper are made to pass so as first to become pasted on one side and
then to be applied one on to the other in order to form a band composed of two or
more thicknesses, substantially as described.
10. In combination with a machine for pasting or cementing paper or other
materials on to boxes, the use of apparatus for turning the projecting edge of the
paper band over the edge of the box and into the interior thereof, and making it
adhere thereto, such apparatus consisting of a step-by-step revolving turntable
carrying the covered boxes in recesses, so as to bring these firstly on to a revolving
disc below the turntable which rotates the box while a stationary beak bends the
edge of the paper over the edge of the box, after which a plunger is made to
descend and press an elastic diaphragm into the box, so as to fold the paper down
and make it adhere to the inner surface thereof, the plunger and diaphragm being
then withdrawn, substantially as described.
