PROVISIONAL SPECIFICATION.
An Improved Manufacture of Paper suitable for Use for Callender
Bowls.
I, JAMES CRAIG, Paper Manufacturer, of Newbattle Mills, Dalkeith, in the
County of Edinburgh do hereby declare the nature of this Invention which has
been communicated to me from abroad by Carl Herm Hanbold, of Chemnitz, Saxouy,
Engineer, to be as follows
This Invention has for its object to provide a "bowl paper" better suited for its
purpose than is such paper as hitherto manufactured. By "bowl paper " is meant
paper used in making bowls for calendering machines for calendering and glazing
paper, cotton goods or other textile fabrics.
According to this invention there is taken wool or woollen rags or other woollen
material (alone or mixed with cotton, linen, hemp, or other vegetable fibres) and it is
subjected to a pulping process and formed into a paper upon a paper making machine
and there is thus produced therefrom a strong soft and thick bowl paper possessing
many advantages over such papers as hitherto manufactured.

An Improved Manufacture of Paper suitable for Use for Callender
Bowls.
I, JAMES CRAIG, Paper Manufacturer, of Newbattle Mills, Dalkeith, in the County
of Edinburgh do hereby declare the nature of this Invention which has been
communicated to me from abroad by Carl Herm Hanbold of Chemnitz, Saxony,
Germany Engineer, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This Invention has for its object to provide a "bowl paper" better suited for its
purpose than is such paper as hitherto manufactured. By "bowl paper is meant paper
used in making bowls for calendering machines for calendering and glazing paper
cotton goods or other textile fabrics.
According to this Invention there is or are taken wool, woollen rags or other
woollen material either alone or mixed with cotton, linen, hemp, or other vegetable
fibres in the form of rags ropes or in other available and suitable form. The
wool or woollen material or the mixture thereof with the other material or materials
selected is subjected to a pulping process and formed into a paper upon a paper making
machine and there is thus produced therefrom a strong soft and thick bowl paper possess-
ing many advantages over such papers as hitherto manufactured. The pulping and
treatment preparatory to making into paper and the making into paper upon the
machine may be conducted in the ordinary way and upon the ordinary machine
but no chemicals should be employed as they would be liable to injure the woollen
fibres.
Having now described and particularly ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is
The manufacture and use of bowl paper consisting of wool or woollen materials
or of a mixture of wool or woollen materials with other fibres substantially as
hereinbefore described.
