I, ERNST GESSNER, of Aue, in the Kingdom of Saxony, Machine Builder, 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:-
This invention has for its object to simplify the construction and improve the
operation of card teaseling machines, to increase their output, and enable them to
operate satisfactorily on tube-like woven articles.
One of the improvements relates to the arrangement of the raising or teaseling
cylinders and drums. This consists in arranging the teaseling cylinders in pairs
so that the cylinders of each pair are in limited contact with each other in such
manner that the teeth of their card clothing partly penetrate or engage with each
other, with the result that the one cylinder acts on the other so as to clean it from
teaseling dust whilst the teeth of the two cylinders mutually and continuously grind
or sharpen each other. By this improved arrangement of the cylinders the cleaning
devices hitherto employed in such machines are greatly simplified.
The second improvement relates to means of distending tubular goods whereby to
cause such goods to be fully extended whilst passing around the teaseling drum and
thus prevent the goods from receiving longitudinal folds.
The accompanying drawing illustrates diagrammatically both of the improvements.
The drum T is provided with teaseling cylinders or rollers grouped in pairs, the two
cylinders ef of each pair being driven at different surface speeds, and being in contact
with each other so that the card teeth of the one penetrate those of the other, the
direction of the teeth and of the running of the rollers being such that the cylinder e
which has the greater surface speed will clean the cylinder f and will itself be freed
from dust by means of the usual cleaning brush mounted beneath the drum.
The improved means of holding tubular goods distended and flattened consists of a
smooth and flexible interposed sheet a of tin, cardboard, or the like material upon
which the tubular woven goods g to be teaseled are drawn and caused to travel around
the drum. The interposed sheet a is of the full width of the goods and fully embraces
the acting part of the drum T following the course of the goods.
In order to prevent the interposed sheet a from being drawn along with the goods,
it is formed or provided at its front end with a pad or thickened up part 6 which is
incapable of passing between cylinders c and whereby the sheet a is held in position
whilst the goods are carried along by the cylinders c and d and thus caused to slide
upon and beneath the interposed sheet a and to travel round the drum T. The device
for distending, and for keeping straight or flattened, tubular goods may also be
employed in teaseling machines having other means of teaseling than the teaseling
rollers shewn, as for instance in those having rotating raising cards.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. In card teaseling machines the arrangement of the teaseling rollers or cylinders
in pairs, the two of each pair being in contact with each other and having different

page_text: surface speeds so that their teeth interpenetrate and those of the one continuously
clean those of the other at the same time that they continuously and mutually sharpen
each those of the other as described.
2. In teaseling machines an arrangement for distending tube-like woven goods to
their full width, consisting of a sinooth flexible sheet interposed between the layers
of the fabric, this sheet being held in position around the teaseling drum whilst the
tube-like goods are drawn over and under the same during the teaseling operation
substantially as and for the purpose specified.
