Improvements in Machinery to be used in the Manufacture of
Spinning and other Rollers.
I, FRANÇOIS FERDINAND MOLIE of 7 Boulevard Morland Paris in the
Republic of France Manufacturer of Spinning Rollers do hereby declare the
nature of the said invention to be as follows:-
-
The invention constituting the subject of the present application relates to an
arrangement of machine to be employed in the manufacture of various classes of
rollers employed in industry such as: drawing rollers, rolling rollers, printing
rollers &c., whatever may be their shape and dimensions but this arrangement of
machine is applicable more particularly to the manufacture of drawing rollers
employed in spinning mills. To produce the said rollers, I roll on their bodies
which are previously coated with a cement made of glue or other similar material
and of bichromate of potash a certain thickness of carded cotton or of other fibrous
material, which thickness or coating is afterwards calendered then covered with
the said cement or composition with which the body of the roller was previously
covered.
To obtain this result, I employ the arrangement of machine which is the object
of the present application and in which the roller to be covered is placed between
two heads.
It is connected to the spindle of the driving head by a mandrel provided with a
chuck which grips one end whilst the other may turn freely in the socket of the
other head.
This being done 1 cover the surface of this roller with the cement above
described in the manner hereinafter described.
The cotton is then rolled upon the roller, the first turn being accomplished by
hand; after it has been completely covered with cotton this latter is highly
compressed by means of cylinders or rollers.
The pressure of the cylinders or rollers is given by means of connecting rods,
levers, links, lever, link and pedal.
The cotton being well felted or compressed, the cylinders are moved out of
contact and the surface is again covered with the said cement.
For this purpose levers carry a reservoir at their ends which is hung upon two
small rods and is loosely mounted so that the reservoir may maintain its vertical
position notwithstanding the displacement of the levers.
The levers being drawn back above the vessel containing the cement the little
reservoir is plunged into the cement so as to fill it and if the levers are loosened
or let go, they will be raised by the action of a spring in such a way that the
reservoir is held above the cement which allows the excess of material to
drain away.
The reservoir is then brought over the cylinder to be cemented by making a
half turn of the levers and it is emptied upon the cylinder by means of a little
handle. A stop upon which the spring abuts, holds the apparatus at a convenient
height.
The roller is then removed and dried after which it is placed in the machine
where it is again made round and smooth by great pressure by means of the
cylinders before mentioned.
Dated this 30th day of January 1893.

Improvements in Machinery to be used in the Manufacture of
Spinning and other Rollers.
I, FRANCOIS FERDINAND MOLIE, of 7 Boulevard Morland, Paris, in the
Republic of Franco, Manufacturer of Spinning Rollers, do hereby declare the
nature of this invention, and in what manner the same is to be performed, to be
particularly described and ascortained in and by the following statement :—
The invention constituting the subject of the present application relates to an
arrangement of machine to be employed in the manufacture of various classes of
rollers employed in industry, such as drawing rollers, rolling rollers, rollers for
use iu printing machines &c., whatever may be their shape and dimensions, but
this arrangement of machine is applicable more particularly to the manufacture of
drawing rollers employed in spinning mills.
To produce the said rollers I wind on their bodies, which are previously coated
with a coment made of glue or other similar material and of bichromate of potash,
a certain thickness of carded cotton or of other fibrous material, which thickness or
coating is afterwards calendered, then covered with the said cement or composition
with which the body of the roller was previously covered.
To obtain this result I employ the arrangement of machine which is the object
of the present application and which will be understood by the following
description, reference being had to the accompanying drawings in which :—
Figure 1 is a vertical section through the centre of the driving shaft.
Figure 2 is a plan and Figure 3 is a transverse section.
As represented in the drawings the roller to be covered is placed between the
two heads A and B. It is connected to the spindle of the driving head A. by a
mandrel a provided with a chuck which grips one end, whilst the other may turn
freely in the socket b of the other head B.
This being done 1 cover the surface of this roller with the cement above
described in the manner hereinafter described.
The cotton is then wound upon the roller, the first turn being accomplished by
hand; after it has been completely covered with cotton, this latter is highly
compressed by means of cylinders or rollers G G'. The pressure of the cylinders
or rollers G Ġ¹ is given by means of connecting rods HH', levers I l', links J,
lever K, link Land the pedal M. The cotton being well felted or compressed,
the cylinders G G³ are moved out of contact and the surface is again covered with
the said cement.
For this purpose the levers N carry at their ends the reservoir O, which is hung
upon two small links P and is loosely mounted so that the reservoir may maintain
its vertical position notwithstanding the partial rotary motion of the levers N.
The levers N being drawn back above the vessel containing the cement, the little
reservoir is plunged into the coment so as to fill it and, if the levers N are
loosened or let go, they will be raised by the action of a spring Q in such a way
that the reservoir O is held above the cement, which allows the excess of
material to drain away. The reservoir is then brought over the roller to be
cemented by making a half turn of the levers N and it is emptied upon the roller
by means of a little handle R. A stop S upon which the spring abut, holds the
apparatus at a convenient height.
The roller is then removed and dried, after which it is placed in the machine
where it is again made round and smooth by great pressure by means of the
oylinders & GT

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In machines for the manufacture of spinning and other rollers, the
combination of two heads A and B centering and holding between them the
roller in course of manufacture during the winding of the cotton or other fibrous
material thereon, a pair of cylinders or rollers GG for the purpose of
compressing the cotton or other. fibrous material wound upon the roller in course
of manufacture and to distribute thereon a layer of cement formed of a mixture
of a gelatinous substance with bichromate of potash, a pedal M, link L, lever K,
rod and links and HH' for operating the cylinders or rollers G G³, and a
cement distributor formed of a reservoir O supported by two small links P
hanging from two levers N, which allow this reservoir to be moved to take a
supply of cement from a vessel and to convey it to the roller to be coated, the
whole being formed, arranged and combined substantially as herein shown and
described.
2. In machines for the manufacture of spinning and other rollers, the
combination of two heads A and B for supporting and rotating the roller being
manufactured, a pair of pressing and cement distributing cylinders or rollers GG¹,
means for forcing such rollers towards each other, a cement distributing
reservoir O, and means for carrying and moving such reservoir to above and away
from the roller being manufactured and to and from the cement tank, all substan-
tially as herein shown and described.
