Cylinders or Tubes of Various Sections.
I, ROBERT SHACKLETON, of the Borough Paper Mills, North Wing, Bradford, in
the County of York, Paper Manufacturer, do hereby declare the nature of this
invention to be as follows:
The object of this invention, is to construct a machine for making in an expeditious
manner, paper cylinders suitable for wrapping ribbons, yarn, and such like thereon;
and other hollow tubes such as may be used for the foundations commonly known as
piece boards, for the reception of textile fabrics on making up the goods for the
merchant, export and retail dealers.
I accomplish my object in the following manner :-To a suitable frame I attach
journals, in which is mounted the axle of the core of a cylinder or piece board
foundation, the section of such core being the same configuration as the section of the
finished cylinder or foundation.
Mounted in another position is a web of paper, which is conducted over a series of
rollers to press rollers covered with flexible material, and so arranged that, one of the
rollers is adjustable for giving the requisite pressure to the rollers for removing the
superfluous paste or other glutinous substance from the sheet or web of paper passing
between them; the bottom roller revolving by preference in a trough containing
glutinous substance, kept at its proper consistency by steam or other heating
agent.
On the sheet or web leaving the press rollers, it is wrapped around the revolving
core to the thickness required, and is pressed or calendered thereon by a heated roller
mounted in such a manner that, the same follows the contour of the cylinder or tube;
and in case a smooth surface is not required, a brush mounted in a similar manner
may be used for pressing the web of paper to the revolving core.
Dated this 20th day of March 1888.

Cylinders or Tubes of Various Sections.
I, ROBERT SHACKLETON, of the Borough Paper Mills, North Wing, Bradford, in
the County of York, Paper Manufacturer, 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 :-
The object of this invention is to construct a machine for making paper cylinders
suitable for wrapping ribbons, yarn, and such like thereon; and other hollow tubes,
such as may be used for the foundations commonly known as "piece boards" for the
reception of textile fabrics on making up the goods for the merchant, export, and
retail dealers and consists in mounting in journals, attached to suitable frames, the
axle of the core of a cylinder or piece board foundation; and in another position a web
of paper which is conducted over a series of rollers to press rollers covered with
flexible material, the bottom roller of which revolves in a trough containing paste or
other glutinous substance, thereby pasteing the sheet or web of paper on passing
between the said rollers; the top roller being adjustable thus giving the requisite
pressure for removing the superfluous paste.
In order that my invention may be better understood, I will further describe the
same by making reference to the accompanying sheet of drawings in which
Fig. 1. represents a side view of my apparatus.
Fig. 2. is a front view of same.
Fig. 3. is a plan, and
Fig. 4. a sectional detail of the press rollers and paste trough.
To the frames A. I secure the journals B. and B' in which I mount the detached
axles C. and C¹ of the core N. for the cylinder or piece board, the section of such core
being of the same configuration as the finished cylinder or foundation.
To the front of each frame A. I secure the brackets E. E. prepared to receive the
axle of a web or roll of paper F. which I conduct over the guide rollers, G. G. G. to
the press rollers H. and H' which are by preference covered with flannel or other
flexible material. The bottom roller H¹ revolves in the trough K. containing paste
or other glutinous substance kept at its proper consistency by steam, hot air, or hot
water circulating through a pipe L. running through the trough K. in any convenient
direction.
The pressure between the pasteing rollers is regulated by turning the hand-
wheels M. M. and screws attached thereto, which apply pressure to the journals
thereby enabling the rollers to remove the superfluous paste or glutinous substance
from the sheet or web of paper F. passing between them.
On the sheet or web of paper F. leaving the press rollers H. and H¹ it is wrapped
round the revolving core N. to the thickness required, thus forming a firm and light
hollow foundation of the same configuration as the core N., which is driven by
belt R. passing over pullies O. and P., the former of which may be mounted on the

page_text: shaft of pasteing roller H¹ as shown, or on any convenient shaft of the machine, and
the latter on one section of the core axle which is made in two parts, the portion C¹
being arranged to slide in the journal-B¹ so that the core N. may be readily placed in
or removed from the machine.
By the paper passing between the covered pressure rollers H. and H¹ as described,
and the circumferential speed of the core N. being slightly in excess of the surface
speed of the rollers. H. and H'; sufficient tension is obtained for wrapping the
several layers or coils of pasted paper tight and compact on the core N., and when
the necessary revolutions or number of layers of paper have been wrapped on the
core, the machine is stopped, and the web of paper F. severed from that of the core ;
when the latter is removed from the machine for taking the foundation from off the
core; which is then replaced and the operation repeated.
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 :-
The method of constructing paper tubes by a machine in which are combined a pair
of pressure rollers and a rotating core N. all being arranged substantially in the
manner and for the purpose as hereinbefore set forth.
