»
MACHINERY A communication from Arnold Munzinger, Olten, Switzerland,
Manufacturer, to be as follows:―
The chain consists preferably of best cotton yarn N° 32 twisted four-ply four
such strands being again united into a single thread by a reverse twist.
Three of these threads pass through the same heddle altogether therefore
4 x 4 x 3 or 48 threads. In each leaf there are 42 threads in 10 centimeters.
By the fulling the width of the fabric is reduced in such measure that there will
be about 55 of the said triple threads in every 10 centimeters.
The weft is of wool and cotton mixed there being about 25 % of wool spun like
in the same manner as what is known in Germany as "Streichgarn" with as little
twist as possible so as to keep the thread soft.
The fabric is woven in very strong power looms being "mounted" or tuned "
as follows for six leaves.

page_text: The leaves which are dotted go up, so that for three shot over there is one shot
under..
This invention may be applied to endless sheets or bands free from joins or
seams and such bands will be found especially useful in paper makers machinery.

I ALFRED JULIUS BOULT of 323 High Holborn in the county of Middlesex,
Engineer do hereby declare the nature of this invention for "IMPROVEMENTS
IN THE MANUFACTURE OF FELT, MORE ESPECIALLY FOR USE IN PAPER-MAKERS'
MACHINERY" (A communication from Arnold Munzinger of Olten, Switzerland
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
The chain consists preferably of best cotton yarn N° 32 twisted four-ply four
such strands being again united into a single thread by a reverse twist.
Three of these threads pass through the same heddle altogether therefore
4 x 4 x 3 or 48 threads.
In each leaf there are 42 threads in 10 centimeters. By the fulling the width
of the fabric is reduced in such measure that there will be about 55 of the said
triple threads in every 10 centimetres.
The weft is of wool and cotton mixed there being about 25 per cent of wool
spun in the same manner as what is known in Germany as "Streichyarn" with
as little twist as possible so as to keep the thread soft.
The fabric is woven in very strong power looms being " mounted" or "tuned "
as follows for six leaves.

page_text: The leaves which are dotted go up, so that for three shot over there is one shot
under.
By means of this Invention endless sheets or bands may be woven free from
joins or seams and such bands will be found especially useful in paper makers
machinery.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is
The herein described manufacture of felt the "mounting" or "tuning" being
arranged as specified and illustrated in the accompanying drawing.
