PROVISIONAL SPECIFICATION.
Improvements in the Production of Printing Rollers.
EPHRAIM ENTWISTLE Senior of the Firm of Epbrain Entwistle & Sons-
Block and Roller Cutters Cranbourne Road Works Ashton-under-Lyne County of
Lancaster do hereby declare the nature of this invention to be as follows:-
This invention relates to surface printing rollers used for printing floor cloth,.
wallpaper &c.
The method now in use is to cast a coating of composition "such as is generally
used in the manufacture of printers inking rollers" round a roller built of wood..
Upon this the design required to be printed is transferred the parts not required to
print, are then cut away, thus leaving the design standing in relief. Bad effects are
very often produced through the wood shrinking, thereby causing the face of roller
to become untrue.
As a preventative against this, I intend to use a metal tubular roller, which can.
be treated in the same manner as a wooden one.
Dated this 9th day of January 1896.
COMPLETE SPECIFICATION.
Improvements in the Production of Printing Rollers.
IEPHRAIM ENTWISTLE, Senior, of the Firm of Ephraim Entwistle & Sons,.
Block and Roller Cutters, Cranbourne Road Works, Ashton-under-Lyne, in the
County of Lancaster, 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 :-
This invention relates to surface printing rollers used for printing floor cloth
wall paper, &c. and the invention will be readily understood from the following
description on reference to the accompanying drawings.
The method now in use for the production of printing rollers is to cast a coating
of composition such as is generally used in the manufacture of printers inking
rollers round a roller built of wood. Fig. 1 represents such a roller ready for
coating, a being a series of wooden rollers, shells or cylinders driven tight upon a
metal mandrel a'.
Upon this roller after coating as before described the design required to be
printed is transferred, the parts not required to print are then cut away, thus
leaving the design standing in relief. Bad effects are often produced through the
wood shrinking and thereby causing the face of the roller to become untrue.
My invention is intended to prevent this defect and for this purpose I use a metal
tubular roller of the required size which can be coated and treated in the same
manner as the roller made or built up of wooden sections.
Fig. 2 shews the two ends (one in section) of a metal tubular roller b ready for
coating and treating to produce a printing roller.

page_text: The metal tubular roller being practically unshrinkable and not made in sections:
will not get out of truth and the printing surface of the roller will therefore not be
rendered untrue by the roller upon which the said surface is cast.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
An improved printing roller produced by forming a suitable tubular metal roller
of the required size which is coated and treated in the ordinary manner to produce.
the necessary printing surface, as hereinbefore described.
