Improvements in Drawing Rollers Employed in Drawing and
Spinning Machinery.
We, WILLIAM AMBLER, of 123, Bramley Street, Bradford, in the County of
York, Engineer, and JAMES EDWARD SHACKLETON, of Eastbrook Paper Tube
Works, Bradford, aforesaid, Paper Tube Maker, do hereby declare the nature of
this invention to be as follows:
This invention relates to improvements in the drawing rollers employed in
machinery for drawing and spinning fibrous material, and its object is to provide
a cheap durable and efficient roller of a sufficiently homogeneous character that the
acting face may be renewed from time to time by simply turning a light cut off the
periphery.
We form our improved rollers of what is known as wood or paper pulp. The pulp
may first be formed into "boards" of suitable thickness then cut into discs a little
larger in diameter than the finished roller and a number of them cemented together
side by side to form a roller of the required width and kept under pressure until
the cement is thoroughly set.
Excellent rollers may be made in this way from what is known as "leather
board" which is made of wood pulp.
Any suitable cement or adhesive material may be used to connect the discs
together and the pressure may be applied in any suitable way as for instance: A
central hole may be made through the disc and the discs mounted on a mandril
with one side against a fixed flange and a loose flange may be pressed against the
other side by means of a screw on the mandril.

Improvements in Drawing Rollers Employed in Drawing and
Spinning Machinery.
We, WILLIAM AMBLER, of 123, Bramley Street, Bradford, in the County of
York, Engineer, and JAMES EDWARD SHACKLETON, of Eastbrook Paper Works,
Bradford, aforesaid, Paper Tube Maker, do hereby declare the nature of this inven-
tion 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 improvements in the drawing rollers employed in

page_text: machinery for drawing and spinning fibrous material, and its object is to provide
a cheap, durable and efficient roller of a homogeneous character that the
acting face may be renewed from time to time by simply turning a light cut off the
periphery.
In describing our invention in detail, reference is made to the accompanying
drawings representing arrangements by which our improved rollers may be con-
structed.
We form our improved roller of what is known as wood or paper pulp, by first
forming the pulp into "boards " of suitable thickness, then cutting the "boards "
into discs D) a little larger in diameter than the finished roller.
Two or more of these discs D are placed together, the surfaces coming in contact
being coated with a starchy cement of any of the farinaceous products such as rice
or wheat, or the cement may be linseed oil varnish, shellac, resin or dissolved india-
rubber. The discs are then placed upon a plate or flange A, and covered by a
flange B, as shown by Fig. 1, through both of which and the discs, passes a mandril
bolt C, provided with a nut E, which when screwed down compresses the discs D
together. It will be readily understood that by extending the flanges in diameter,
a series of bolts may be placed around same and thus assist the centre bolt C, and
bring pressure on the discs D.
The discs D are held compressed until the cement is thoroughly set, the rollers
are then removed, placed upon spindles and turned to the diameter required.
It will be obvious that other means of obtaining the necessary amount of pressure
may be adopted, as for example, placing the flanges A, and B, with the discs D,
between, under a screw press, or subjecting them to hydraulic pressure, in which
case a mandril M as shown by Fig. 2, fixed to the bottom flange A, takes the place
of the before mentioned bolt C, and is of such length that, when pressure is applied
to the flanges with the cemented discs D, of "board" between, the end of the
mandril M will not protrude beyond the upper surface of the top flange B, when
the discs are pressed together.
Rollers constructed in the manner as before described are of equal solidity, and
are pressed, forced or shrunk on the spindles in a similar manner as is now
employed with the ordinary wood formed and leather covered rollers now in common
use, and when turned true, a perfectly level and equally elastic periphery is
obtained, free from hard knotty places, by which more perfect draughting is obtained,
with less pressure on the tightening screws than is the case with rollers made of
wood or iron and covered with leather as is now the common practice; with the
advantage that they can be renewed by turning the face when the latter is
damaged by wear and tear or other means.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
The construction of drawing and spinning top front rollers of wood or paper pulp
disc "boards" cemented and compressed together substantially in the manner
described and for the purpose as hereinbefore set forth.
