Improvements in Coverings for Rollers used in Textile Machinery.
1 JAMES SHEPHERD of "Holly House" Davenport near Stockport in the County
of Cheshire, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to coverings for rollers used in spinning, drawing roving,
and other Textile Machinery so as to reduce the cost of such covering below the now
almost universal system of using cloth and prepared calf skin, and to obtain a longer
wearing and a cleaner surface when in use.
To obtain a sufficiently firm and elastic covering for the top rollers used in con-
nection with Textile Machinery I employ a very thin tough paper, in the form of
tape, of any required width and length, and by the aid of suitable appliances I wind
this "
paper tape" round that part of the roller intended to be covered, until a
sufficient quantity has been wound on so as to form a firm but slightly compressible
or elastic body.
The paper is first secured to the roller by glue, or any suitable cement, and 'the
last or finishing folds are also secured to each other by the same means.
When the covering of the roller is complete 1 varnish the outer surface of the
paper over with a quick drying composition of shellac dissolved in methylated spirit
or other suitable quick drying varnish may be used, but the composition here
specially named renders the surface of the paper covering impervious to oil or grease,
so that in use it retains a clean surface, and is not so liable as leather to collect
particles of fibre, causing loss of material, and bad work.
I am
aware that various kinds of paper tubes have been made and used for
covering rollers, and also that papier-maché under varied conditions has been tried
for the purpose; but these differ materially from the use of layers of thin tough paper
wound continuously and closely over each other forming a series of fine interstices
sufficient to impart a degree of flexibility to the body of the covering and which I
claim to be novel and useful.

Improvements in Coverings for Rollers used in Textile Machinery.
I JAMES SHEPHERD of Holly House Davenport near Stockport in the County of
Cheshire Engineer 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 coverings for rollers used in connection with spinning,
drawing, roving, and other Textile Machinery, and the objects are to cheapen the cost
of such coverings below that of the now almost universal system employed of using
cloth and prepared calf-skin. Also to provide a suitable covering of the necessary
amount of elasticity, and firmness, to secure the production of good work, and one
that can be run in a right or left hand direction without fraying or destroying the
joint of the covering, a fault common with all coverings made with short bevel
joints.
To obtain a sufficiently firm and elastic covering for top rollers that are used
in connection with Textile Machinery, and upon which so much depends for the even
quality and strength of the yarn as well as the prevention of loss from waste, I cover
that portion of a metallic roller, or a roller of any other material, or rollers made

page_text: up of a combination of materials over the parts intended to be covered with a thin
tough paper in the form of "Ribbon or Tape of the required width, and by suitable
machinery or appliances I wind-this paper "Ribbon or Tape" upon the roller one fold
close upon another until a sufficient quantity has been wound on to give the necessary
strength and elasticity of covering. Layers of thin paper 'wound close upon each
other though possessing considerable solidity nevertheless retain a certain amount of
elasticity due to the number of fine interstices that remain between the unsecured
folds of the paper, and it is this quality that renders paper covering for top rollers
specially useful in connection with Textile Machinery.
In wrapping or winding the paper covering upon a roller, the first layer must be
secured to the roller with glue, or other adhesive substance, and the last or finishing
folds must be secured to each other in a similar manner, so as to give thickness, strength,
and durability to the outer surface.
I wish distinctly to state that this invention is not for the purpose of making paper
cylinders or tubes by wrapping paper one fold upon another to any required form or
dimension, but to be used as described, and for the specific purpose of forming elastic
coverings for top rollers used in connection with Textile Machinery.
When the covering of a roller is completed I varnish over the outer surface and
edges of the paper folds with a quick drying composition of shellac dissolved in
Methyllated Spirit, or any suitable and quick drying paper varnish may be used. A
good varnish will render the outer surface of the paper covering impervious to oil or
grease, is easily kept clean, and very durable.
Having now described my improvements and the means I adopt in carrying the
same into effect what I claim is :-
First. Covering top rollers used in connection with Textile Machinery of whatever
material, or materials the rollers may be made, or in parts composed, with strips of thin
tough paper in manner, and for the purposes hero with fully described.
Second. Continuous winding layer upon layer of thin tough paper upon rollers
forming an outer covering of an elastic nature due to the number of fine interstices
between the unattached parts that are set closely together.
Third. Varnishing the outer surface of paper covered rollers used in connection
with Textile Machinery as a means to prevent absorption of oil or grease.
