PROVISIONAL SPECIFICATION.
An Improved Material for the Backs or Foundations of Card
Clothing.
I, WILLIAM SCHOLES, of Scite House, Liversedge, in the County of York,
Card Manufacturer, do hereby declare the nature of this invention to be as
follows:-
I use a suitable fibrous material, which is reduced to a soft uniform mass, or
pulp, and then gathered in very thin layers or sheets and laminated or laid one
over the other until the required thickness is obtained, when it is taken and
submitted to a great pressure. The sheets thus formed are next passed through a
bath of oil or sufficiently oiled by any other suitable means, and after being
thoroughly dried, are finally taken and cut to the requisite length and breadth
according to the purpose for which they are required.

An Improved Material for the Backs or Foundations of Card
Clothing.
1, WILLIAM SCHOLES, of Scite House, Liversedge, in the County of York,
Card 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 :-
I use a suitable fibrous material, which is reduced to a soft uniform mass or pulp,
and then gathered in very thin layers or sheets and laminated or laid one over the
other until the required thickness is obtained great care being exercised in the
lamination to cross the fibre of the pulped material so that the straining power will
be about equal both ways after the moisture has been partially drained or other-
wise extracted from the sheets thus formed they are submitted to a great pressure
and are then passed through a bath of oil or sufficiently oiled by any other suitable
means, and after being thoroughly dried, are finally taken and cut to the requisite
length and breadth according to the purpose for which they are required.
In carrying out my invention I adopt the same machinery and appliances known
and used in the paper trade for the making of brown paper boards, and the like.
After the material has been pulped by the means stated it is takeu in thin sheets
or layers, and laminated, or the thin sheets or layers laid one over the other.
After the first sheet is laid I run a brush ligthly over it lengthwise in order to lay
the fibres lengthwise; then when the next sheet is laid I run the brush crosswise
to lay the fibres crosswise, and so alternate lengthwise and crosswise until the
requisite quantity is laid for the thickness required; by this means I get equal
straining power both ways in each laminated sheet or board when completed.
Before beginning to build up or form the laminated sheet, I first lay a piece of
canvas of sufficient size, on which I build the laminated sheets, and after a sufficient
D

page_text: number of layers have been built up or laid I put another piece of canvas on the
top. This I repeat with each sheet or board I form by lamination, and when I
have done the required quantity, after the water is sufficiently drained out of
them, they are submitted to a considerable pressure, for a period of two or more
hours.
After this the boards or sheets thus formed by lamination are separated and
divested of their canvas sheets, and thoroughly dried, when each sheet or board is
taken separately and totally immersed in a bath of oil or sufficiently oiled by any
other suitable means, and after they have been dried again they are ready for use.
The wires or card teeth after the foundation is formed as hereinbefore described
are inserted in the same manner as for leather or other. foundation or back now
in use.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
The use and application of pulped material for the backs or foundations of card
clothing substantially as and for the purpose set forth.
