PROVISIONAL SPECIFICATION.
Apparatus suitable for Use in connexion with Napping or Teazling
Machines.
I, LOUIS SCHNEIDER, of Mittweida, Saxony, Germany, Managing Director, do
hereby declare the nature of this invention to be as follows:-
The selvages of woollen cloth consist very often, as is well known, of material
other than the body of the cloth itself, and in the manufacture and finishing of
the cloth assume a wavy form; they are often also thicker than the body of
the cloth to be napped.
When the cloth comes to be napped or teazled in a napping or teazling machine,
the action of the wire cards or natural teazles of the machine on' the somewhat
prominent portions of the wavy selvages, which are generally thicker than the
body of the cloth, is so marked that the selvages are too much teazled and often
entirely or partly denuded of nap. The edges of the cloth are in each case
rendered unsightly and bare and difficulties are caused in its further finishing-
for instance, in the stretching out or mounting by the selvages.
Now apparatus according to this invention is intended to be applied to a
napping or teazling machine and to raise the wavy selvages of the cloth at or near
the place where the wire cards or teazles act upon the cloth, so that the selvages
will be preserved from excessive napping or teazling.
Such apparatus comprises a rod which extends across the drum and is furnished
at each end with a comparatively thin cross piece standing in a plane at right
angles thereto and bent around or hooked at both ends. The cross-pieces rest on
the guide rolls of the napping or teazling machine with their hooked ends
embracing the latter, and can shift sidewise--i.e., in a direction parallel to the
axes of the guide rolls. In order that the position of the end pieces may be
adjusted exactly to the width of the cloth, the aforesaid rod is telescopic, so that it
can be lengthened or shortened. A set screw serves to keep it at the required
effective length. Instead, however, of this set screw arrangement, a helical spring
adapted by its tension always to hold the end pieces against the edges of the cloth,
may be provided at each end of the aforesaid rod.
Un each end-piece there is an angular shield, which has in its lower part a pro-
jecting finger, which at its lower end has a piece adapted to project (at right angles
thereto and parallel to the axis of the card-drum) under the selvage. This shield
can be slid along the end-piece and held in the desired position by a set-screw
which passes through a slot in the shield and engages the end-piece.
On the end-piece there is a finger which prevents the selvage from turning under,
which otherwise might happen.
The shield with its finger is preferably placed not at the place where the carding
or teazling is effected, but so that the cloth will pass over its finger a little before
reaching that place, as if it were placed there the raising of the selvage by the
horizontal part of the finger of the shield would also remove a part of the body of
o the cloth itself from the desired action of the wire cards or teazles. The selvage,

page_text: which is a little longer than the body of the cloth, is therefore raised by the
finger before the cloth reaches the place where it is napped or teazled, just enough
to prevent undesirable action on the selvage of the cards or teazles. Since the
two end pieces are adjusted to the edges of the cloth the entire apparatus will
follow any sidewise' inotion of the cloth which may ensue during the course of the
latter through the napping or teazling machine, so that even in case of such side-
wise motion the selvages will be properly raised away from the action of the
napping or teazling rollers.. 11
The effect of this apparatus is a marked improvement in the appearance of the
cloth that is napped or teazled in the machine, because the wavy' selvages are in
no way roughened or otherwise unfavourably affected by the cards or teazles.

Apparatus suitable for Use in connexion with Napping or Teazling
Machines.
I, LOUIS SCHNEIDER, of Mittweida, Saxony, Germany, Managing Director, 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:-
The selvages of woollen cloth consist very often, as is well known, of material
other than the body of. the cloth itself, and in the manufacture and finishing of
the cloth assume a wavy form; they are often also thicker than the body of
the cloth to be napped.
When the cloth comes to he napped or teazled in a napping or teazling machine,
the action of the wire cards or natural teazles of the machine on the somewhat
prominent portions of the wayy selvages, which are generally thicker than the
body of the cloth, is so marked that the selvages are too much teazled and often
entirely or partly denuded of nap. The edges of the cloth are in each case
rendered unsightly and bare and difficulties are caused in its further finishing-
for instance, in the stretching out or mounting by the selvages.
Now apparatus according to this invention is intended to be applied to a
napping or teazling machine and to raise the wavy selvages of the cloth at or near
the place where the wire cards or teazles act upon the cloth, so that the selvages
will be preserved from excessive napping or teazling.
Fig. 1 of the accompanying drawings shows at a the drum of a napping or
teazling machine, which is furnished at its periphery with rollers covered with
wire cards or with natural teazles b, b, b, b. d are the guide rolls and c the feed
rolls, which cause the cloth to travel in a course from a to x and present it to the
periphery of the drum a. This arrangement and its repetition about the periphery
of the drum are well known. The apparatus is shown to a larger scale in plan in
Fig. 2, in side view in Fig. 3, and in end view in Fig. 4. It comprises a rod e
which extends across the drum and is furnished at each end with a comparatively
thin cross piece of standing in a plane at right angles thereto and bent around or
hooked at both ends 9 g. The cross-pieces f rest on the guide rolls d d with their
hooked ends 99 embracing the latter, and can shift sidewise-i.e., in a direction
parallel to the axes of the guide-rolls. In order that the position of the end
pieces may be adjusted exactly to the width of the cloth, the rod e is telescopic,
so that it can be lengthened or shortened. The set-screw h serves to keep it at

page_text: he required effective length. Instead, however, of this set-screw arrangement,
helical spring (Fig. 5), adapted by its tension always to hold the end pieces f
gainst the edges of the cloth, may be provided at each end of the rod e.
On each end-piece f there is an angular shield k, which has in its lower part a
projecting finger 1, which at its lower end has a piece o adapted to project (at right
angles thereto and parallel to the axis of the card-drum) under the selvage. This
shield k can be slid along the end-piece f and held in the desired position by a
set-screw m, which passes through a slot in the shield and engages the end-
piece f.
On the end-piece f there is a finger n, which prevents the selvage from turning
under, which otherwise might happen.
The shield with its finger is preferably placed not at the plane * (Fig. 1)
where the carding or teazling is effected, but so that the cloth will pass over its
finger a little before reaching that place, as if it were placed at 6* the raising of
the selvage by the horizontal part o of the finger would also remove a part of the
body of the cloth itself from the desired action of the wire cards or teazles. The
selvage, which is a little longer than the body of the cloth, is therefore raised by
the finger, before the cloth reaches the place where it is napped or teazled, just
enough to prevent undesirable action on the selvage of the cards or teazles.
Since the two end pieces f are adjusted to the edges of the cloth, the entire
apparatus will follow any sidewise motion of the cloth which may ensue during
the course of the latter through the napping or teazling machine, so that even
in case of such sidewise motion the selvage will be properly raised away from the
action of the napping or teazling rollers.
The effect of this apparatus is a marked improvement in the appearance of
the cloth that is napped or teazled in the machine, because the wary selvages
are in no way roughened or otherwise unfavorably affected by the cards or
teazles.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. Apparatus for napping or teazling machines for the purpose of preventing
the injurious effect of wire cards or natural teazles on the wavy selvages of cloth,
comprising guides f g adapted to be adjusted to both edges of the cloth, so that
they will follow any sidewise movement of the cloth on the guide rolls, by means
of connecting cross-rods e furnished with either hand-adjusting devices (h, Figs. 2
and 3) or automatic adjusting devices (i, Fig. 5) and adjustable fingers o pro-
jecting from the guides and adapted to raise the selvages in order to remove them
wholly or partially from the action of the wire cards or teazles.
2. Apparatus for preventing the injurious action of the cards or teazles of
napping or teazling machines upon the selvages of cloth treated therein, con-
structed and arranged to operate as herein before described with reference to and
shown in Figs. 1, 2, 3, and 4 of the accompanying drawings or as modified accord-
ing to Fig. 5 thereof.
