Improvements in Machinery or Apparatus for Fastening the Corners
of Card-board Boxes and like Articles.
I, JULIUS MOHS, of 10 Grunestrasse, Dresden, Machinery Maker, do hereby
declare the nature of this invention to be as follows :-
:-
This invention relates to machinery or apparatus for fastening the corners of
cardboard boxes and the like in which a strip of paper or other suitable material is
first coated on one side with several stripes of adhesive substance the said strip is
theu fed by a feeding device a certain distance into a striking block, and is then
cut off, and finally struck in separate lengths by means of the striking block down
upon the corners of a cardboard blank that has been bent into the required shape
(box-form for instance) and is resting on an anvil.
A machine according to my invention can be driven by power or by hand and is
provided with treadle-mechanism which serves to throw the actuating mechanism
for the striking block into gear at the proper time.
An arrangement of such a machine is as follows:-At the rear part of a suitable
framing I arrange apparatus for applying a number of longitudinal streaks or
stripes of adhesive substance (hereinafter called paste) on to the strip of paper or
other suitable material which is unwound from a roll; these several stripes of
paste being separated from each other by one or more non-pasted portions of the
strip. The strip thus coated with paste, passes along a trough shaped guide to the
front of the apparatus where it enters the movable head of the machine, which
head, in combination with the insertion of a strip of material coated with a
number of separate stripes of paste, constitutes an essential part of the invention.
This movable head consists of a feeding device, a cutting-off device, and a striking
block; and these three parts form a common moving whole.
The
This mutual relation and common motion of the aforesaid three parts gives the
advantage that the pasted strip is inserted with certainty from the feeding device
into the striking block; that the shears which serve to cut off the lengths of strip
and which move with the aforesaid parts, will operate with certainty; that the
strip will not be shifted in the direction of its movement by the cut; that by means
of the apparatus to be more precisely described hereinafter, the parts will not be
made sticky by the stripes of paste on the paper strip; and that the operation of
all the parts will be effected from the main shaft only by means of a connecting
rod, all the other movements being effected by means of stationary curves.
main shaft is carried by standards or a framing in front of the pasting device; it
has at its rear end a driving wheel or pulley and at its forward end there is
mounted a crank disc with a crank pin on which is pivoted a depending rod which
is connected at its lower end to the striking block. The connection is preferably
made by means of an eccentric bolt by adjusting or turning which there is
produced an exact fit or impact of the angular or roof-shaped recess of the striking
block upon the correspondingly bent cardboard upon the anvil. The striking
block is guided in a vertical groove in the frame of the machine.
When the treadle is depressed, a lever arrangement causes a disengager to be
moved away from a projection on the main shaft whereby the crank disc is
rotated, and the striking block moved down.
When the pressure is removed from the treadle, the disengager is moved by a

page_text: spring under the projection from the main shaft, thereby causing the crank disc to
become stationary.
The feeding-mechanism is attached to and moves with the striking-block, and
consists mainly of a feeding wheel around the periphery of which the paper strip
coming from the channelled guide above referred to is partially carried, and is
thence pushed horizontally in between knife or shear blades and through the latter
into slots in the lower surface of the striking block. The feeding wheel is rotated
by means of a small ratchet wheel and pawl when the head of the machine rises,
the arrangement being such that the pawl is guided or turned in a bent groove in a
vertical bar fixed on the machine framing. This bar is vertically adjustable by
means of a screw in a slot of the bar, according to a divided scale, whereby the
length of feed of the strip is determined by the ratchet mechanism. The length of
strip for pasting each corner is obviously dependent on the height of the box or
other article to be pasted together.
When the strip is being fed forward by the rotation of the feeding wheel, the
strip lies with its dry or non-pasted side on the periphery of the wheel. For the
purpose of feeding the strip forward, it must be seized or held by the feeding part,
and for this purpose the feeding wheel is partly surrounded by a shoe or curved
strip which is pressed by a spring against the feeding wheel. The inner surface of
this shoe is of such contour, that at the places where the stripes of paste are situated
on the strips, the said inner surface has recesses in the direction of its length so that
this inner surface never comes into contact with the paste. Between these recesses
there is a longitudinal rib, and against this rib there presses the periphery of the
feeding wheel, or a prominence projecting slightly beyond the periphery of the
wheel. In this manner the strip is seized, whilst being fed forward, so that none of
the feeding surfaces comes in contact with the paste stripes on the strip.
Instead of the shoe just referred to there may be employed a small wheel
bearing against the periphery of the feed-wheel, said small wheel being formed,
similarly to the shoe, with a longitudinal rib and with a recessed contour, so that
the strip is gripped, for feeding, between the two wheels without the paste stripes
on the strip being touched.
The separate paste stripes upon the strip of material are made by the paste
apparatus at the rear of the machine, by means of a disc or wheel whose periphery
is provided with two annular prominences preferably consisting of rubber, and to
the surfaces of which prominences the paste is transferred by delivery rollers.
Two or more stripes of paste may be applied to the strip of material but generally
two paste stripes are sufficient for the machine for fastening together the corners of
cardboard boxes. After the strip, on the upstroke of the head of the machine, has
been inserted into the striking block, the length of strip is cut off by the shears on
the downstroke of the head.
The shear blades are pivoted to the movable machine head the ends thereof
remote from the cutting edges take by means of antifrictional rollers in the guide
grooves of a disc which is rotated by means of a lever mounted on its centre; the
end of said lever being guided in the curved slot of a fixed bar. The entrance of
the said end of this lever in the curved portion of the slot causes the disc to rotate,
and the shear blades to move so as to cut off the length of strip fed in between
them by the feed device and inserted in the block.
The strip is situated between the shear blades with the paste stripes facing
towards the lower shear blade.
The guide curves in the disc are therefore of a shape such that the lower shear
blade is moved up only to the line of passage of the paper strip, whilst the upper
shear blade moves past this line and thus effects the cut. This arrangement
ensures that the position as regards direction of the strip shall not be changed or
shifted by the cutting operation, so that when the strip is fed forward again, it will
enter accurately into the grooves provided for it in the block.
In the preceding description it has been stated that the strip is coated with
separate stripes of paste in the machine.

page_text: It is however allowable to apply the separate stripes of paste to the strip
previously, and to insert the strip with the separate paste stripes in a dry state into
the machine. In such a case, the coating apparatus is adapted to apply moisture
to the separate paste stripes for the purpose of moistening and dissolving the
paste.
It will be evident that machinery according to my invention may be variously
modified without departure from its distinguishing characteristics.

Improvements in Machinery or Apparatus for Fastening the Corners
of Card-board Boxes and like Articles.
1, JULIUS MOHS, of 10, Grünestrasse, Dresden, Machinery Maker, 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:
This invention relates to machinery or apparatus for fastening the corners of
cardboard boxes, and the like in which a strip of paper or other suitable material
coated on one side with several stripes of an adhesive substance, is, by means of a
feeding device, pushed forward a certain distance into a striking block and is
then cut off, and finally struck down in separate lengths by means of the striking
block, upon the corners of a cardboard blank that has been bent for example into
the shape of a box and is resting on an anvil.
A box of this kind, pasted together at its four corners as by a machine
according to this invention, is represented in Fig. 1 of the accompanying
drawings.
A machine according to my invention is represented in sectional side elevation in
Fig. 2; as shown it is adapted to be driven by power, but it may, if desired, be
driven by hand and is provided with treadle mechanism which serves for throwing
the actuating mechanism for the striking block into gear at the proper time.
A represents a belt driven pulley carried by a sleeve A¹ on a shaft, B mounted
in a suitable frame B. At the rear part of this frame there is arranged an
a paratus C for applying a number of longitudinal stripes of an adhesive material
(hereinafter called paste) to a strip of paper or other suitable material, which is
unwound from a roll D, the several stripes of paste being separated from one
another by one or more non-pasted portions of the strip. The strip thus coated
with paste, passes along a trough-shaped guide E to the front of the apparatus
where it enters the movable head of the machine, which head in combination with
the strip of material coated with a number of separate stripes of paste, constitutes
an essential part of this invention. The movable head (of which Fig. 3 is a
perspective view drawn to a larger scale than Fig. 2) consists of a feeding device,
a cutting-off device, and a striking block; and these three parts form a common
whole and move together.
It results from this mutual relation and common motion of the aforesaid three
parts that the pasted strip is inserted with certainty from the feeding device into
the striking block; that the shears which serve to cut off lengths of material from
the strip and which move with the aforesaid parts, operate with certainty, that the
strip is not shifted out of the direction of its movement by the cut; that, by means
of the apparatus to be more precisely described hereinafter, the parts are not made
sticky by the stripes of paste on the paper strip; and that the motion of all the

page_text: three parts is produced from the main shaft of the machine by means of a
connecting rod only all the individual movements being effected by means of
stationary curves or cams.
On the front end of the main shaft B, is a crank-disc a having a crank-pin on
which is suspended a rod which is connected at its lower end to the striking
block c. The connection is preferably made by means of an eccentric bolt d by
adjusting or turning which there can be produced an exact fit or impact of the
angular or roof-shaped recess of the striking block e (Fig. 3) upon the
correspondingly bent piece of cardboard resting on the anvil e. The striking
block c is guided in a vertical groove in the frame of the machine.
When the treadle g is depressed, a lever g' causes a disengager g² to be moved
away from a projection on the end of an engager g³, (as will be seen from the
position of the parts shown in Fig. 2,) whereupon the engager 93, which is pivoted
within a groove in the main shaft B, is caused by a spring to enter a slot in the
sleeve A, thereby connecting the main shaft to the sleeve in a well known manner,
so that the crank-disc a will be then rotated, and the striking block c moved
downward.
When the pressure is removed from the treadle, the disengager g² is moved by
a spring g under the projection on the engager 93, thereby causing the crank-disc a
to become stationary.
The feeding-mechanism is attached to and moves with the striking block c and
consists mainly of a feeding wheel h. Around the periphery of this wheel the
paper strip coming from the channelled guide E is partially carried, and is thence
pushed horizontally in between knife or shear blades and thence into slots k k¹
in the striking block c (Figs. 3 and 3A). The feeding wheel is rotated by means
of a small ratchet wheel and a pawl when the movable head of the machine
rises, the lever carrying the pawl being provided with an antifriction roller that is
guided or moved in a bent groove in a vertical bar m fixed on the machine
framing and by which the pawl lever is operated as the head moves up and
down. The bar m is made vertically adjustable by means of a screw n extending
through a slot o in the bar in order that the extent of feed of the strip at each
operation of the ratchet mechanism can, by the aid of the divisions of a suitable
scale be varied to suit different requirements. The length of strip for pasting
each corner is obviously dependent on the height of the box or other article to
be pasted together.
When the strip is being fed forward by the rotation of the wheel h, it lies with
its dry or non-pasted side on the periphery of the wheel. In order to feed the
strip forward, it must of course, be firmly taken hold of or engaged by the feeding
part, and for this purpose the wheel is partly surrounded by a shoe or curved
strip p, which is pressed by a spring against the wheel h so as to create the
necessary friction between the strip and the said wheel. The inner surface of
the shoe p is of such cross section (see Fig. 4) that at the places where the stripes
of paste are situated on the strips, the said inner surface has recesses or grooves
extending in the direction of its length so that this inner surface never comes into
contact with the paste. Between these recesses there is a longitudinal rib q
which presses the strip against the periphery of the feeding wheel h, or against
a prominence projecting slightly beyond the periphery of that wheel.
result of this arrangement is that although the strip is adequately held against
the wheel for feeding, no surfaces of the feeding device come into contact with
the paste stripes on the strip.
The
Instead of the shoe p just referred to there may be employed a small wheel ¹
(Fig. 5) which bears against the periphery of the feed-wheel h, and is formed,
similarly to the shoe, with a circumferential rib and a recessed cross section, so
that the strip is gripped, for feeding, between the wheels and without their
touching the paste stripes on the strip.
To facilitate the fixing of the strip of material on the cover of the cardboard
box or the like, it may, in some cases be preferable to feed the strip of material

page_text: to the striking block e not in a flat form, but in an angular form corresponding
to that of the said corner. For this purpose the feeding device must, of course,
be of corresponding shape and may be such as that shown in sectional elevation
in Fig. 7 in which instead of having their peripheries shaped as shown in Fig. 5
the wheels and are shaped as shown and engage with each other angularly,
one of them, being provided with a middle rib g and side ribs forming together
on the roof-shaped periphery of this wheel grooves towards which the stripes of
paste on the strip face, so that the periphery of the wheel ' does not come into
contact with the moist paste. One of the wheels e.g. the wheel has shown may
be pressed towards the other by a spring u, so that the strip will be securely
held between the wheels h and ¹ for feeding.
The separate paste stripes are made upon the strip of material by the pasting
apparatus C (Fig. 2) at the rear of the machine by means of a disc or wheel X
(Fig. 6) whose periphery is provided with two annular prominences Z Z which
preferably consist of rubber and to the surface of which the paste is transferred
by delivery rollers. Two or more stripes of paste may be applied to the strip
of material, but usually two paste stripes will be found sufficient for fastening
together the corners of cardboard boxes.
After the strip, on the upstroke of the head of the machine, has been inserted
into the striking block, the length of strip is cut off by the shears on the down-
stroke of the head. For this purpose, the shear-blades are pivoted to the movable
machine-head at and the ends thereof remote from the cutting edges engage
by means of antifriction-rollers, in the cam grooves of a disc which is rotated by
means of a lever arm fixed to its centre, the end of this lever arm being guided
during the vertical movement of the aforesaid head, in the curved slot of a fixed
bar 2. The entrance of the said end of the lever arm into the curved portion of
the slot causes the disc to partly rotate, and the shear-blades to move so as to
cut off the length of strip fed in between them by the feeding device and inserted
into the block c. The strip is situated between the shear-blades with the paste
stripes facing towards the lower shear-blade.
The guide or cam grooves in the disc r are of such a shape that the lower shear-
blade is moved up only to the line of passage of the paper strip, whilst the upper
shear blade moves past this line and thus effects the shearing of the strip. This
arrangement ensures that the position as regards directions of the strip shall not
be changed or shifted by the cutting operation, so that when the strip is fed
forward again, it will enter accurately into the grooves k k¹ provided for it in the
block c (Figs. 3 and 3^).
In the preceding description it has been stated that the strip is coated with
separate stripes of paste in the machine; it will, however, be understood that the
separate stripes of paste may be made on the strip previously and the strip inserted
into the machine with the separate paste stripes in a dry state. In such a case, the
coating apparatus Cinstead of applying paste to the strip is caused to apply water
to the separate dry paste stripes for the purpose of moistening and dissolving the
paste.
It will be evident that machinery according to my invention may be variously
modified without departure from its distinguishing characteristics.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1. In machinery or apparatus for fastening together the corners of cardboard
boxes and like articles, in which a strip to be pasted on a corner of the box or
other article is fed in the requisite length to a striking block for pasting on, an
intermittently operated machine-head comprising a strip feeding device, a cutting-off
device, and a striking block, these parts being connected so as to move together,
so that the invariable relative positions of these parts will ensure that the strip
shall travel in a path that is fixed relatively to the said parts as it is being moved

page_text: forward by the feeding device through the cutting device and into the striking
block, substantially as described.
2. In machinery or apparatus for fastening together the corners of cardboard
boxes and like articles by means of a strip of paper or like material, means such
as a disc provided with projecting annular parts, and delivery rollers, whereby
separate longitudinal stripes of adhesive material or moisture can be applied to the
strip so that it can be gripped whilst being fed, without soiling the feeding device,
substantially as herein described.
3. In machinery or apparatus for fastening together the corners of cardboard
boxes and the like, the use in combination with a machine-head of the kind specified
in Claim 1, of fixed bars such as m and 2 having curved guide or cam grooves
adapted to produce the feeding movement and the cutting movement of the shear-
blades on the upstroke and the downstroke respectively of the entire machine-head,
substantially as described.
4. In a feeding device for machinery or apparatus for fastening together the
corners of cardboard boxes and like articles by means of a strip of paper or like
material provided with stripes of adhesive material, a shoe (p) having longitudinal
ribs and grooves corresponding in number and arrangement to the uncoated and
coated portions of the strip so that the shoe will not touch the stripes of
adhesive material when the strip is pressed thereby for feeding, substantially as
described.
5. In a feeding device for machinery or apparatus for fastening together the
corners of cardboard boxes and like articles by means of a strip of paper or like
material provided with stripes of adhesive material, a pair of feeding wheels or
rollers the peripheries of which are so relatively formed as to grip only the uncoated
portions of the strip of coated material fed between them, substantially as herein
described.
6. My improved machine for fastening the corners of cardboard boxes and like
articles, constructed, arranged, and operating as hereinbefore described with
reference to and shown in the accompanying drawings.
