PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Absorbent Sheets, Rolls,
or Pads of Paper for Blotting, Filtering, and other similar
Purposes.
I EDWIN GRUNDY WRIGLEY of Preston in the County of Lancaster Paper
Manufacturer do hereby declare the nature of this invention to be as follows:-
The object of this invention is to manufacture sheets, rolls, or pads of absorbent
paper of a stronger and firmer character and consequently more durable than that
made entirely from cotton rags or from wood pulp, and which at the same time
possesses a great power of absorption.
The improved paper is composed of wood cellulose in combination with cotton rags,
and with vegetable fibres of a grassy nature.
This combination of fibres is very suitable for the manufacture of strong absorbent
paper for the purposes indicated and has not hitherto been used for such manu-
facture...
According to my invention the various vegetable fibres above mentioned are mixed
together in a beating engine and are thereby prepared in the form of paper pulp, and
this pulp may then be manufactured into paper by an ordinary paper making machine
in the usual way but I prefer to use in such machine additional "felts" so arranged
that the paper will be pressed between two "felts" whilst it is in a semi-dry condition
instead of passing through the press rolls in the ordinary way. The object of this is
to keep the fibres open and thereby increase the absorbent nature of the paper.
I do not wish to confine myself to the particular proportions in which these three
kinds of vegetable fibre are combined but I may state that I find the following
admixture to yield a satisfactory result namely; to about sixty parts of wood cellulose
I add about twenty parts of cotton rags, and about the same quantity of the grassy
vegetable fibre.

The manufacture of sheets rolls or pads of paper for blotting filtering and other
similar purposes by the combination of wood cellulose with cotton rags and with
vegetable fibres of a grassy nature substantially as hereinbefore described.
