Improvements in and relating to the Take up Motions of Lace
Machines and other Looms.
I, WILLIAM HENRY SMITH, of 27 Rue du 29 Juillet, Calais, in the Republic
of France, Designer do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus for rolling up tulle, lace, curtain and other
fabrics.
It is well known that in tulle-looms when the roller on which the fabric is rolled
is worked direct, the diameter increases proportionately to the thickness of the
said fabric and the speed with which the same is carried away gradually increases
in consequence.
In order to obviate this inconvenience the employment of a delivering or driving
roller independent of the receiving roller has been suggested; but by reason of
the arrangement of the apparatus the portion of the tulle in contact with this
delivery roller is very small, and in order to make the tulle adhere to the said
delivery roller and be carried away in consequence the said roller had to be
furnished with points or spikes which could penetrate the tulle and thus carry it
along. These points have however the inconvenience of perforating the manu-
factured materials.
The object of the present invention is to obtain a uniform movement of the
fabric without using spiked rollers.
The invention consists essentially in disposing a delivery roller covered over
with a rough material in such a manner with regard to the direction of motion
of the fabric that the surface of contact between the fabric and the said roller
shall be as large as possible.
With regard to the receiving roller it may be driven either by contact with
the delivery roller or through the medium of friction wheels or in any other
suitable manner.
The loom carries ztandards which bold the delivery or driving roller and the
receiving roller.
The delivery roller is driven by a toothed wheel and an endless screw or in any
other suitable manner. In general it is in contact with the receiving roller but
on the side opposite to that on which the fabric is formed. This fabric arrives
at the said delivery roller and is in contact with the same for the entire length
of a large arc. The fabric then passes to the receiving roller which is driven
by friction, and wound upon the said roller.
The receiving roller is mounted in a slot in the support or standard so that
as the thickness of the tulle increases it descends to the slot.
A spring holds
the said receiving roller against the delivery roller. The spring may be replaced
by a counterweight or other equivalent device.
The adherence produced by the surface of contact is so great that a very slight
pressure suffices for carrying away and rolling up the fabric. This latter is not
then crushed or squeezed and is carried away with great regularity.
It is evident that the position of the delivery roller can be varied with respect
to the receiving roller and the arched bar, but according to the principle
enunciated the surface of contact between the tulle and the delivery roller must
always be very great.
In a
modification in which the delivery roller is placed below the receiving
roller, a guide roller directs the material so that the surface of contact is still
very large.

page_text: I reserve the right to all dispositions based on the principles herein before
formulated. A third arrangement presents this feature that the two rollers are
no longer directly in contact. The delivery roller drives the receiving roller
by means of two friction rollers of such a diameter that the circumferential velocity
of the receiving roller will be slightly greater than that of the delivery roller, it
follows from this that the fabric will be stretched between the two rollers, which
will further augment the adhesion of the same to the delivery roller. When the
tension becomes too great the pulleys slide one on the other which prevents the
fabric being torn. The springs or counterweights allow the maximum tension to
be regulated.
The delivery or driving roller can be covered with cloth, smooth or rough
indiarubber, or with any other convenient material.
In the last construction the receiving roller has only a movement of rotation
and does not move with regard to the other roller. It is sufficient to place it
at such a fixed distance away from the other roller, that there will be room to
roll up the fabric.
It is evident that I can apply the hereinbefore described method of rolling
the material to looms of any description without departing from the nature of my
invention.

Improvements in and relating to the Take up Motions of Lace
Machines and other Looms.
1. WILLIAM HENRY SMITH, of 27 Rue du 29 Juillet, Calais, in the Republic of
France, Designer, 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 a take-up motion or apparatus for rolling up tulle, lace,
curtain and other fabrics as such are woven.
It is well known that in lace machines and other looms when the roller on which
the fabric is rolled is worked direct, the diameter increases proportionately to the
thickness of the said fabric and the speed with which the same is carried away
gradually increases in consequence.
In order to obviate this inconvenience the employment of a delivery or driving
roller independent of the receiving roller has been already adopted; but by reason
of the arrangement of the apparatus the portion of the tulle or fabric in contact
with this delivery roller is very small, and in order to make the tulle adhere to the
said delivery roller to be carried forward thereby, the said roller had to be
furnished with points or spikes which penetrate the tulle and thus carry it along.
These points have however the inconvenience of perforating the manufactured
material.
The object of the present invention is to obtain an uniform movement of the
fabric without using spiked rollers.
The invention consists essentially in arranging a delivery roller covered over
with a rough material in such a manner with regard to the direction of motion of
the fabric that the surface of contact between the fabric and the said roller shall
be as large as possible.
With regard to the receiving roller upon which the material is rolled it may be
driven either by contact with the delivery roller or through the medium of friction
wheels or in any other suitable manner.

page_text: I his invention is shown on the accompanying drawing in which Fig. 1 shows one
of the arrangements which allow the object of the invention to be carried out.
The loom carries standards S which hold the delivery or driving roller M. and
the receiving roller R.
The delivery roller M is driven by a toothed wheel E and an endless screw or in
any other suitable manner. In general it is in contact with the receiving roller R
but on the side opposite to that on which the fabric is formed the fabric reaches
the delivery roller M at a and is in contact with the same for the entire length of
the arc abc. The fabric then passes ate to the receiving roller R which is driven
by friction and is wound upon the said roller.
The receiving roller R is mounted in a slot C in the support or standard S so
that as the thickness of the tulle wound upon it increases it descends in the slot.
A counterweight and a lever, as shown in Fig. 1, holds the receiving roller R
against the other roller, but any other suitable equivalent device may be employed.
The adherence produced by the surface of contact abc is so great that a very
slight pressure at c suffices for carrying away and rolling up the fabric. This
latter is not then crushed or squeezed at c and is carried away with great
regularity.
It is evident that the position of the delivery roller M may be varied with
respect to the receiving roller R and the centre bar B, thus Fig.
arrangement slightly differing from the first but in which according to the
shows an
principle enunciated the surface of contact a be between the tulle and the delivery
roller is always very great.
I reserve the right to all arrangements based on the principles hereinbefore
formulated. A third arrangement shown in Figs. 3 and 4 presents this feature that
the two rollers M and R are not directly in contact.

that the circumferential velocity of the receiving roller R will be slightly greater
than that of the delivery roller M it follows from this that the fabric will be

the same to the delivery roller M. When the tension becomes too great the
pulleys P P slide one on the other which prevents the fabric being torn.

The delivery or driving roller M can be covered with cloth smooth or corrugated
indiarubber, or with any other suitable material.
It is
In the last forms of construction the receiving roller R has only a movement of
rotation and does not move its position with regard to the other roller.
sufficient to place it at such a fixed distance away from the other roller that there
will be room to roll up the fabric the slide C being dispensed with.
It is evident that I can apply the hereinbefore described method of rolling the
material to looms of any description without departing from the nature of my
Invention.
Having now particularly described and ascertained the nature of the said inven-
ion and in what manner the same is to be performed, I declare that what I
laim is :-
1. In the take up motion of lace machine and other looms the arrangement of a
riving or delivery roller, which receives the piece of material, in such a way that
he latter only leaves the driving roller, in order to be wound on the receiving
oller, after having remained in contact with almost the whole of the circumference
f the driving roller, with the object of producing the adhesion and uniform
elivery of the material.
2. In the take up motion of lace machines and other looms the combination
f the driving roller with a receiving roller, mounted in a slide of the support
r standard, and held pressed against the driving roller in all its length by a
ever and counterweight or other suitable device, with the object of causing the

page_text: receiving roller to be operated substantially as hereinbefore described and with
reference to Figs. 1 and 2 of the accompanying drawing.
3. In the take up motion such as above described, the combination of the
driving roller, and the receiving roller having respectively friction rollers at their
extremities, contact being made by these friction rollers at two points by means of
springs, or other suitable device, the diameters of the rollers being such, that the
circumferential speed of the receiving roller may be slightly greater than that of
the driving roller, with the object of producing a tension on the lace, and of
increasing its adhesion to the driving roller, substantially as hereinbefore described
and with reference to Figs. 3 and 4 of the accompanying drawing.
