Improvements in Carding Machines.
We, SAMUEL LEDEREB, and JOSEF DLOUHÝ, both of Nachod, Province of Bohemia,
Austrian Empire, Managers of a Spinning Mill, 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 relates to carding machines, and it has for its object to give to the
fibres of the wad, which passes round the licker-in or otherwise enters the carding
machine, parallel positions without injury to the said fibres, and also to remove leaves
and other impurities from the wad without producing much waste.
According to the invention, the purpose in view is attained by the employment of a
flat cross piece, which is arranged immediately beneath the point of entrance of the
wad and extends over the whole breadth of the carding machine, the upper surface of
the said cross piece being covered with card surface or set with similarly acting teeth,
and holes being provided in the said cross piece for admitting of the impurities
combed out falling through.
On the accompanying sheet of drawings,
Fig. 1 is a sectional elevation of the licker-in of a carding machine, provided with
the device forming the subject of the invention;
Fig. 2 shews the said device in front and end elevations.
The said device consists of a plate A, the length of which corresponds to the
breadth of the carding machine, and the front surface of which is made concave
according to the convex cylindrical surface of the licker-in. The said concave surface
is covered with card cloth or set with carding teeth a in such a position that they
exert a combing action on the wad carried along by the licker-in B.
Furthermore, the said plate A is provided with a number of holes a¹, widening
toward their outer end, and intended to allow the combed-out impurities to fall
through.
This plate A, which extends over the whole breadth of the licker-in B, is arranged
immediately beneath the feeding table b or other feeding device, so as to form the first
operative part of the machine.
The described device has for its effect that the fibres of the wad under treatment
assume parallel positions without being injured, so as to be submitted to the following
carding operation in this condition, whereby the quantity of waste is considerably
reduced. At the same time foreign matters contained in the wad, such as leaves and
the like, are combed out and caused to fall through the holes a¹.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a carding machine, a plate arranged immediately beneath the point where the
wad is fed into the machine, and extending along the whole breadth of the machine,
the said plate having its inner surface so covered with card cloth or set with carding
teeth that a combing action is exerted on the fibres of the wad while holes formed in
the said plate admit of the combed-out foreign bodios falling through, substantially as
described.
2. In a carding machine, the combination of the feeding device and the licker-in
with a plate facing the licker-in immediately below the feeding device, this plate

teeth that a combing action is exerted on the fibres carried along by the licker-in,
holes being provided in the plate for allowing the combed-out foreign bodies to fall
through, substantially as described.
