Improvements in Machines for Covering Wire and the like.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings in the County of Middlesex, 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 is represented in the accompanying drawings in which :-

This invention relates to an improvement in machines for covering wire with a
ribbon or strip of fabric or similar material, which is folded around the wire and
caused to adhere thereto by any suitable sizing,
The covering of flat wire with a ribbon or strip of fabric, the strip being secured
thereto by an adhesive material applied to the strip before or as it is being folded
upon the wire, the wire itself being drawn through an apparatus in a continuous
run, the folding of the strip upon the wire being produced as the wire is thus drawn
through the apparatus, is a well known operation for covering wire. Such covered
wire is cut into lengths for various purposes.
The cutting of the wire severs both the covering and the wire at the same point,
so that the end of the wire is exposed, and some protection is necessary for the ends
of the wire thus exposed, particularly where the pieces of covered wire are employed
for dress or corset-stays, hence after the covered wires have been cut to the required
length, a subsequent operation is necessary to complete the stay. In some cases
the subsequent operation consists in applying a metal or other tip over the end of
the stay to cover the end of the wire, and so as to afford a protector between that
end of the wire and the garment. In other cases the wire so covered is again
covered with a braid or fabric, and so that the second covering may project beyond
the ends of the wire, and by some manipulation form a protection for that end of
the wire.
The object of the present invention is the construction of a machine which will
cut the wire into the required lengths during the operation of covering, and before
the cut end of the wire shall have been inclosed, and so feed the wire that after it
is cut the cut piece will advance from the end of the body of the wire from which
it is cut so as to leave space within the covering between it and the next piece cut,
and so on, a succession of pieces being cut from a continuous run of wire, but so fed
as to leave a space within the covering between the successive wires, the covering
being closed between the ends of the successive wires, the two thicknesses of the
covering pressed and caused to adhere together, and then the covering cut in the
space between the ends of the wires, and so as to leave a projecting end of

page_text: the covering stiffened by adhesive material to form a tip upon both ends of each
piece of wire so cut, of sufficient stiffness to not only form a protection over the
end of the wire, but also to facilitate the introduction of the stays into the pockets
prepared to receive them in corsets, dresses, or wherever it is necessary to apply
such stays, the stays thus produced being each complete in itself, and without the
necessity of any subsequent operation thereon, and the invention consists in the
combination of mechanism as hereinafter described, and particularly recited in
the claim.
A, represents the bed of the machine, which is in the form of a plate standing in
a vertical plane, and supported upon legs, or otherwise. BC represent a pair of
feed-rolls, arranged one above the other, and between which the wire D, runs.
Revolution is imparted to the feed-rolls in the direction indicated by arrows, so as
to draw the wire into the machine, the wire coming from a reel, or other source of
supply, in the usual manner. The rolls are driven by the application of power
thereto, through a pulley E, or otherwise, the two rolls caused to work together by
means of gears F G, on the opposite ends of the arbors, the arbors of the rolls
extending through the bed, and supported therein in the usual manner for sup-
porting similar feed-rolls, their pressure being adjusted, also in the usual manner,
by means of an adjusting screw H, and a spring I below it.
One of the rolls, preferably the upper, is arranged upon its arbor, so as to permit
a slight circumferential play of the roll, and this is accomplished by arranging in
the arbor a stationary key or spline C', and forming a key-seat C" in the roll, of a
greater width than the thickness of the spline, so that while the spline will engage
one end of the seat C, and impart revolution to the roll, it will permit the roll to
advance faster than the arbor, as occasion may require, and as hereinafter
described.
At a point distant from the feed-rolls B C, a second pair of feed-rolls J and K,
are arranged, they being connected by gears L and M on the opposite end of the
roll arbors in like manner as the rolls B and C are geared together, and the two
pairs of feed-rolls are connected together by a train of gearing, as seen in Fig. 2,
so as to make the operation of the feed-rolls simultaneous.
The diameter of the feed-rolls J and K, is greater than the diameter of the two
rolls B and C, so that the surface velocity of the rolls J and K, is greater than
that of the rolls B and C, or, which is the same thing, the rolls J and K, may
be of the same or less diameter than the rolls B and C, they being geared accord-
ingly, it only being essential that the surface velocity of the second pair of
feed-rolls JK shall be greater than the surface velocity of the first pair of
feed-rolls B C.
Between the two pairs of feed-rolls and at a point near the second pair of rolls, a
folder N, is arranged, through which the wire runs. O, represents the strip or
ribbon of covering material, which is drawn from any convenient supply, and passes
to the folder over a roll P, so as to enter the folder, and being engaged with the
wire will travel with the wire through the folder, the folder serving to fold the
strip around the wire. This is a common and well known device, and does not
require to be particularly described.
Before the covering reaches the folder, the surface of the covering which is to
lie next the wire is coated with an adhesive material. As here represented the
coating is accomplished by means of a roller Q, arranged to revolve in a tank R,
which contains adhesive material, the upper surface of the roller being above the
tank, and at one side of the roller Q, a guide-roll S, is arranged, beneath which the
strip passes, thence over the roller Q, and thence under a roll T, on the opposite
side of the adhesive rollers Q, thence the covering passes to the roll P and into
the folder. As the strip passes over the roller Q, it receives a coating of adhesive
material upon that surface which is to come next the wire, and so that when the
covering is folded around the wire, the adhesive material will firmly attach the
covering to the wire, and secure the two edges of the covering together. This is a
common and well known device for applying adhesive material to a strip of covering

page_text: which is to be applied to the wire, and for which other known devices for the same
purpose may be substituted.
The feed-rolls J K draw the wire through the folder with the covering, the
folder operating to fold the covering around the wire, and as usual in wire covering
machines employing like or similar devices.
Between the folder and the first pair of feed-rolls a cutting device is introduced,
which at a predetermined time, and after the advancing wire shall have entered
between the second pair of rolls J K, will cut the wire. The wire being drawn
inward by the first pair of feed-rolls B C, at a velocity corresponding to the surface
velocity of that first pair of rolls, the wire will advance to the second pair of feed-
rolls JK, the surface velocity of which is greater than that of the first pair of
feed-rolls, and this second pair of feed-rolls taking the wire, will naturally cause it
to advance faster than the first pair of feed-rolls, and that second pair of feed-rolls
may thus advance the wire faster than the first pair of feed-rolls for a certain
length of time, one of the first pair of feed-rolls here represented as C, is provided
with the lengthened key-seat C, so as to permit that roll to be turned at a velocity
faster than that which would be imparted to it by its arbor, that is, an over-motion
is permitted that roll C, so that when the run of the wire is taken by the second
pair of rolls J K, it will advance with the surface velocity of those rolls J K, the
roll C, because of its elongated key-seat readily yielding for such increased
velocity given to the wire over that which would be imparted by the first pair of
feed-rolls B C.
The cutting of the wire occurs during the over-motion permitted in the first pair
of feed-rolls, and as soon as the wire is cut, the second pair of feed-rolls will lose
their control over the body of the wire, that body of the wire then coming under the
control solely of the first pair of feed-rolls, and so soon as the key has caught up
with the roll those feed-rolls will again advance the body of the wire, but at a
slower velocity than that which will now be given to the piece of wire cut off, and
which is between the second feed-rolls J K. The piece of wire so cut and now
under the control of the second pair of feed-rolls J K, will advance more rapidly
than the body of the wire, consequently before the end of the body of the wire from
which the piece was so cut reaches the second pair of feed-rolls J K, a space
will have been produced between the rear end of the cut piece and the advancing
end of the body of the wire corresponding to the increased velocity which is
given to the piece of wire so cut.
The cutting of the wire occurs so far to the rear of the folder that before the end
of the body of the wire shall have reached the second pair of feed-rolls, the requisite
space will have been formed between the first cut piece and the end of the body of
the wire.
The covering is drawn through the folder at the same velocity with the wire
passing between the feed-rolls JK and is folded around the wire so passing between
those rolls, the folding of the wire continues through the space between the end of
the piece of wire and the end of the body of the wire, so as to double the covering
through the said space, and the drawing and cutting of the wire and the folding of
the covering around the successive pieces of wire will continue, the covering being
pressed upon the wire and through the spaces, the adhesive material causing the
covering to adhere together through the spaces. The cutter operates to cut the
pieces of wire from the body whenever the requisite length of wire shall have
passed between the cutters, and this length will vary accordingly as the stays are
required to be longer or shorter.
While the cutting of the wire may be made instantaneous and so as not to
interfere with the advance of the wire, it is desirable to produce the cut by means
of cutters which during the cutting operation will advance with the wire, and then
after the cut is completed return for the next cut, and this is desirable because a
much greater rapidity of work can be produced than when the cutting is
intermittent, and also more rapid than can be practically produced by substantially
instantaneous cuts.

page_text: In the drawings, a cutting device is shown, which is adapted to advance with the
wire during the operation of cutting; this device is shown enlarged in Fig. 4.
Through the bed A of the machine is a longitudinal slot U, and on the wire feeding
side of the bed A, a slide V is arranged, having a rib W, (see Fig. 3) on its inner
side, which extends through the slot U, in the bed A, so as to be guided in its
longitudinal movement. On the slide V, a lever X is hung, upon a pivot Y, and so
as to swing in a vertical plane. At its forward or free end the lever X carries a
cutter Z, and below the cutter is a bed or guide u, over which the wire passes, the
end of this bed forms a companion cutter for the cutter Z, and between which two
cutters the wire runs, and so that when the cutter is depressed from the position
seen in Fig. 1, to that seen in Fig. 4, the cutter Z will descend and produce the cut
of the wire. A. spring b, is arranged below the lever, the tendency of which is to
raise the cutter, and which yields upon the depression of the cutter to produce the
cut of the wire. The cutter is operated by a cam-lever e, hung upon a fulcrum d,
so as to swing in a plane parallel with the plane of the cutter-lever X. A lever e
is hung upon a fulcrum f, between the two levers c and X, and so as to swing in
substantially the same plane, one arm of the lever c, is connected to one arm of the
lever e, by a link g, and the other arm of the lever e, is connected to the lever ✗,
by a link, and so that an up and down movement imparted to the lever will
impart a corresponding up and down movement to the cutter lever X, and as from
the position seen in Fig. 1, to that scen in Fig. 4 and return.
C,
A longitudinal movement is imparted to the cutter-slide V, corresponding to the
advance movement of the wire running between the two cutters, and as here
represented this advance is produced by means of an endless drive-chain i, see Fig. 2,
running over a sprocket-wheel j, which is in gear connection with the train which
drives the feed-rolls, so that its travel may correspond to the travel of the second
pair of feed-rolls J K, for the reason that the cutting is to be produced while the
wire is advancing under the operation of the second pair of feed-rolls, hence the
cutter must travel at the same velocity as the wire travels under the operation of
the said second pair of feed-rolls.
The drive-chain extends downward and passes around a corresponding sprocket-
wheel k, below, the drive-chain is provided with lugs or shoulders, which in the
advance movement of the drive-chain are adapted to engage a corresponding lug or
shoulder m on the slide or rib W of the slide, as seen in Fig. 2.
The lugs, are arranged distant from each other corresponding to the time
required for the requisite length of feed of the wire to be produced between the
cuts, and so that at a predetermined time one of the lugs on the drive-chain will
strike the shoulder of the cutter-slide and cause that slide to advance accordingly,
and as indicated in broken lines Fig. 2, and as also indicated in broken lines Figs. 1
and 4, and the length of time occupied in the advance movement of the slide,
corresponds to the time required for the descent and return of the cutter.
To produce the descent of the cutter while the slide is advancing, the lever c, is
constructed with a cam-shaped groove n, and above the lever e, a lever o is hung,
upon a pivot p, stationary on the bed of the machine. The lower arm of the lever o
carries a stud % which works in the groove n of the lever c. The upper arm of
the lever rests against a stationary stud or shoulder r, when the cutter is in the rear
position, as seen in Fig. 1, and in this position the stud q stands at the forward end
of the groove in the lever; the groove from that point is upwardly inclined rear-
ward, consequently as the cutter-slide advances, as from the position seen in Fig. 1,
to the position seen in Fig. 4, the cam shape of the groove n, operating upon the
stud q, causes the forward end of the lever c to be depressed to produce a downward
movement of the cutter Z, as clearly seen in Fig. 4, but during the time of this
descent, the cutters have been advancing at the same rate of speed as the covered
wire which is passing between the second pair of rolls, consequently no interruption
or opposition has been produced by the feed.
After the cut has been made the cutter must return; the cut is produced during
the first part of the forward movement of the slide. After the cutter has descended

page_text: to cut the wire, and as seen in Fig. 4, the slide still advances, but the groove n in
the slide from this point is inclined downward, and so that as the slide advances the
lever e will be raised, as indicated in broken lines Fig. 4, and this raising of the
lever c will also raise the lever X and the cutter Z, as indicated in broken lines
Fig. 4, so that before the cutter ceases its forward movement, it has risen to a
point above the wire, so that it may retreat without interference with the advance
of the wire. After the cutter has been thus raised, the slide is returned to its first
position, as seen in Fig. 1.
As here represented, the return of the cutter-slide is produced by a second drive-
chains, running over a sprocket-wheel t, which like the sprocket-wheel 3, is in gear
connection with the feed-rolls.
By the time the cutter slide has been returned, the body of the wire has advanced*
so that its end is about to engage with the second pair of feed-rolls, and it is now
necessary to open the feed-rolls in order that the body of the wire may advance
under the more rapid operation of the second pair of feed-rolls, until the time for
cutting occurs.
To relieve the wire from the operation of the first pair of feed-rolls while the body
of the wire is being so advanced by the second pair of feed-rolls, the return of the
cutter-slide is adapted to raise the upper feed-roll C, so as to separate the two rolls
and permit the wire to pass freely between them. This may be accomplished as
seen in Fig. 6. The box D¹ in which the arbor E' of the roll is supported, is
adapted to slide up and down below the box D', a lever F1 is hung upon a
fulcrum G', the shorter arm_adapted to bear upward against the under side of the
box D', the other arm extends forward and is provided with a toe H', which stands
in the path of the cutter slide as it returns, and so that in the last part of the return™
movement of the slide, a corresponding lug or cam I' on the cutter-slide will strike
the toe of the lever F¹, depress the toe arm of the lever, and correspondingly raise
the box which supports the upper feed-roll, and also raise the feed-roll as indicated
in broken lines Fig. 1, and so that so long as the slide remains in its normal or rear
position, the feed-rolls B C will be separated so as to permit the wire to run freely
through them, but so soon as the cutter-slide starts in its advance movement to
produce the cutting, the two feed-rolls B C come together upon the wire, but the
over motion permitted the roll C, will still permit the wire to run freely between
them until the wire is cut, as before described, when the feed-rolls B C will come
into operation and advance the wire slower than the rolls J K advance the piece of
wire so cut, and as before described.
The slide V, is connected to a second slide », by a bar u, through a slot w in the
bed, as shown, the purpose of this second slide will be hereafter described.
The drive-chain s, is provided with lugs or shoulders r, one of which is adapted
at the proper time to engage a shoulder or projection y on the bar u, it being
understood that the sprocket-wheel t runs in the opposite direction to the sprocket-
wheel, consequently this engagement by the second drive-chain s, with the bar u
will impart a return movement to the cutter slide, and bring it to its position for
the next cut.
As the cutter-slide returns from its extreme forward position indicated in broken
lines Fig. 4, it will operate upon the lever o, through the stud 7, and that lever o
being then free to swing upon its fulcrum p, will turn under the retreating move-
ment of the slide, its upper arm passing from the stud or shoulder r, as seen in
Fig. 5, until the stud 7 reaches the highest point in the groove n, and this will
occur when the slide has ahout reached its extreme rear position. The lever o is
provided with a spring, the tendency of which is to yieldingly hold it against its
stud or shoulder r, this spring yields upon the return of the cutter-slide, as
indicated in Fig. 5, the spring being stronger than the spring, holds the cutter
in its up position, but as soon as the slide reaches its rear position, the stud
passed over the rise of the groove, then under the reaction of its spring = the lever
will be drawn against its stud r, the stud 9 passing freely through the incline of
has

page_text: the grooven, until the lever o, reaches its home position, as seen in Fig. 1, where
it is ready to operate upon the next advance of the cutter-slide.
In practice it is found that a space of about one-fourth of an inch between
successive wires is sufficient to produce the requisite tip for the stay. As before
stated the two thicknesses of covering are pressed together, and so that their
-coated surfaces will firmly adhere, and so that when they are separated midway of
the space, the projecting ends stiffened by adhesive material will form a serviceable
tip for the ends of the stays, and so as to fully cover the metal, and form a pro-
jection to prevent contact between the ends of the wire and the pocket or garment
into which the stays are introduced.
To give the proper finish to the tips thus formed, as well as to facilitate their
introduction into pockets, the ends should be pointed, as seen in Fig. 7, which shows
a portion of a covered wire on an enlarged scale, including the space between the
adjacent wires. To properly form these ends, as seen in Fig. 7, a portion of the
covering is cut away upon cach side, the cut extending across so as to separate
the two and produce the pointed ends.
To cut the covered wire midway between the ends of adjacent wires, a cutter is
arranged to operate at the required point in advance of the wire, and so as to cut
the covering at the desired point between the ends of successive wires, and while
as stated in regard to the wire cutter this cut may be made instantaneous, it is
desirable that this cut shall be made by the cutters which advance at substantially
the same rate of movement as that of the covered wire.
The cutter to thus cut off the covered wires is arranged upon a slide v, which, as
before described, is connected with the slide V by means of the bar U, the con-
nection being through a longitudinal slot in the bed.
To cut out a portion of the covering to produce the required shape of the
end, as before described, the cutters are in the form of dies, the male die 4 is
arranged in a vertical slide 5, upon the slide v, and the bed 6 below the die 4
is provided with a female die corresponding to the male die 4, and between which
two dies the covered wire passes, and so that the male die operating as a punch
will at the proper time be brought upon the space in the covering of the wire,
and so as to punch therefrom a portion of the material to give the requisite shape
and separate the covered wires from each other.
The cutter slide 5 is operated by means of a lever 7, similar to the lever c,
and is hung to the slide upon a fulcrum 8, the lever 7 being constructed with
a cam-groove like the cam-groove n, of the lever c, except that it is oppositely
arranged, and the movement of the lever 7 is communicated to the slide 5 by
an intermediate lever 10, hung upon a fulcrum 11 on the slide, and connected
to the lever 7 by a link 12, and in combination with this lever 7 is a lever 13,
hung upon a fulcrum 14, like the lever o, and carrying a stud 15 to work in
the cam-groove of the lever 7, the same as described regarding the lever o, the
lever 13 being provided with a stationary shoulder or stud 16, and a yielding
spring 17 like the lever o, and the lever 10 is provided with a spring 18, to
operate as does the spring upon the lever X. The position of the second cutter
with relation to the first is such that the operation of the second cutter will be
produced at the time the space between the successive wires will have been brought
to the said second cutter, it will be understood therefore that the cutter slides are
to be adjusted with relation to each other according to the length of wire to be
cut, or stay to be formed.
Either or both lugs or shoulders by which the drive-chain engages the slide may
be adapted to be thrown out of the path of the lugs on the respective chains, so
that the cutters may stand inoperative, and such arrangement will be a convenience
when introducing a new wire, or a new covering strip.
As illustrated at the left in Fig. 2, the lug y by which the chain engages the
slide is hinged to the bar or slide as at 19, and so that it will rest against the
shoulder 20 when in the down position, that it may engage the lugs on the drive-

page_text: "
chain, but if the lugs y be turned upward, as seen in broken lines, then it will be
out of the path of the lugs on the chain, and no engagement will occur, conse--
quently when the slides have been advanced by the advancing drive-chain, and the
cutters opened, they will remain in that position so long as the lug y is turned up
out of the path of the engaging lugs on the drive-chains, and no cutting effect
can be produced until the lug y is returned. Spring-cushions 21 and 22 are-
arranged at opposite ends of the two grooves in which the cutter slides work, and
so as to make the stop of the slides easy and without cushioning or jar.
As an
While the construction and arrangement of the cutting mechanism described is-
preferred, other cutting devices may be employed as before indicated.
illustration of such a cutting device a pair of rotary cutters are represented in
Fig. 8. This device consists of a pair of heads 23 and 24, carrying cutters respec-
tively 25 and 26, and which at the proper time will come together upon the wire,
as indicated in broken lines in same figure, and thus cut off the wire. In this
arrangement the rotary movement of the cutters will correspond to the advancing
movement of the wire, and the arrangement of the cutters will be such that when
the requisite length of wire has been taken, the cutters will come together, and
cut off the required length, the invention is therefore not to be understood
as limited to any particular construction of cutters except as hereinafter-
described.
While preferring to make the second or separating cut so as to produce sub-
stantially a pointed tip for the covered wire, the cut may be simply a square cut,
as indicated by the line 27 Fig. 7, or it may be a diagonal cut, as indicated by the
line 28 in the same figure.
The covering devices for the wire have been described as being adapted to fold.
the strip of material around the wire, but other equally well known devices may
be employed for covering the wire, such for illustration as a braiding machine,.
arranged before the second pair of feed-rolls, and through which the wire will
pass, the covering so braided having adhesive material applied to it, so as not only
to secure the covering to the wire, but attach the two thicknesses at the ends to.
stiffen the projections, as required for the tips. Such a braiding machine and its.
arrangement with a pair of feed-rolls is too well known to require illustration, while
therefore the folding device adapted to fold a strip of covering around the wire-
is preferred, the invention is not to be understood as limited to any particular-
mechanism for covering the wire.
The cut of the wire produced between the first and second pair of rolls may
occur just as the wire is about to enter the second pair of rolls, in which case the
over motion of the feed-rolls and the opening movement of the rolls on the return
of the cutter slide may be omitted, but yet the arrangement for interrupting the
operation of the first pair of feed-rolls as described, is preferred.

extent of over-motion, a second pair of feed-rolls through which the wire passes
from the first pair of feed-rolls, the surface movement of the second pair of feed-
rolls being greater than that of the first pair of feed-rolls, a covering mechanism
through which the wire passes to said second pair of feed-rolls, a longitudinal slide
arranged between the covering mechanism and said first pair of feed-rolls, the
said slide having a longitudinal movement imparted to it corresponding to the surface
movement of said second pair of rolls, the said slide carrying a cutting mechanism

page_text: through which the wire passes, and adapted to cut the wire while the slide is
moving with the wire, mechanism between the said slide and the said first pair of
rolls, substantially as described, and whereby in the return movement of said slide
the said first pair of rolls are separated.
Seventh. In a machine for covering wire in which a mechanism is provided for
a continuous feed of the wire, the combination therewith of a longitudinal slide
arranged to move in a path parallel with the advancing movement of the wire,
mechanism substantially such as described to impart to said slide an advancing
movement corresponding to the advancing movement of the wire, a cutter stationary
on said slide, a lever hung to said slide and carrying a second cutter, between
which two cutters the wire passes, a second lever hung to said slide, and in con-
nection with said cutter lever, the said second lever constructed with a cam-shaped
groove, and a lever hung upon a stationary axis and so as to swing in a plane
parallel with the path of movement of the slide, the said stationary lever carrying
a stud adapted to work in the said cam-shaped groove on the said second lever, the
said stud-carrying lever held stationary in one direction, but free in the opposite
direction, substantially as described, with mechanism to return said slide, and
whereby under the advancing movement of said slide, the cutters will close, and
then open before the slide returns.
Eighth. In a machine for covering wire, the combination of a pair of feed-rolls
between which the wire passes, a second pair of feed-rolls through which the wire
also passes, the surface movement of said second pair of feed-rolls being greater
than that of said first pair of feed-rolls, a folder between said pairs of rolls, and
through which the wire passes to said second pair of rolls, mechanism substantially
such as described to coat and conduct to said folder a strip of material, a cutting
mechanism between the folder and the first pair of rolls, adapted to cut the wire
at a predetermined time, and so that the portion so cut from the body of the wire
will advance under the revolution of the second pair of rolls more rapidly than
that of the body of the wire, and thereby leave a space of the covering material
between the end of the one piece so cut and the end of the next piece, a second
cutting mechanism arranged beyond the said second pair of rolls, and adapted to
cut the covering between the ends of the covered pieces of wire, substantially as
described.
Ninth. In a machine for covering wire, a pair of feed-rolls between which the
wire to be covered passes, a second pair of feed-rolls through which the wire also
passes, the said second pair of feed-rolls having a surface velocity greater than
that of the first pair of feed-rolls, a covering mechanism substantially such as
described between the two pairs of rolls, and through which the wire to be covered
passes to said second pair of rolls, a cutter between said covering mechanism and
the said first pair of rolls, adapted to cut the wire at a predetermined time, the
portion so cut being engaged by the second pair of rolls, and consequently advanced
at a greater velocity than that of the body of the wire fed by the first pair of
rolls, and whereby a space will be formed within the covering between succeeding-
pieces of wire, a cutter beyond the said second pair of feed-rolls arranged to.
separate the covered pieces at a point in the covering between the adjacent ends of
the pieces of wire, mechanism substantially such as described for imparting to both
said cutters a longitudinal movement during the cutting operations at substantially
the same velocity as that of the covered wire, and substantially as described.
