Improvements in Carding Engines.
T, SAMUEL BERAU, of Obrowitz, Brünn, in the Province of Moravia, in the
Empire of Austria, Spinner, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:
The purpose of the present invention is a carding-machine in which the inferior
and shorter material left behind upon the cylinder by the doffer is taken off by
a system of card-covered rollers underneath the doffer which are connected with
the cylinder and is vigorously carded and mixed with the material taken off by
the doffer the mixture being again submitted to a further carding-process.
In the accompanying drawing is illustrated a carding-machine provided with
the arrangement referred to, the construction and working of which, in other
respects, is well known.
The system of card-covered rollers referred to consists of a worker e close to the
cylinder which takes off the short material left on the cylinder a by the doffer b
and cards it in conjunction with the clearer f. The clearer f carries the material
to the (auxiliary) cylinder where it is again worked by the cards of the two
rollers and y. Above the clearer there is a beater or fancy roller d which,
having raised or loosened the inferior material on the cylinder a before being taken
off by the worker e acts upon the auxiliary cylinder and in connection with the
latter operates again upon the material taken up by the cylinder g by which means
the fibres are evenly straightened, which is absolutely necessary for the formation
of a uniform sliver.
At the surface of contact of the doffer b and auxiliary cylinder the material
taken up by them (b and g) is intimately mixed and the mixture well carded so
as to leave the surface as a uniform. and homogeneous flerce us it is taken off by
the doffer comb to he condensed into a sliver.
The object of the roller or clearer fi placed before the surfaces of contact of the
doffer band auxiliary cylinder 18 to separate the inferior fibres carried along by
the doffer and auxiliary cylinder g.
It is evident that in the arrangement here described another series of workers
such as e and clearers such as may he interposed between the clearer f and
auxiliary cylinder g.
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:-
A carding-machine characterized by having underneath the doffer ba system
of card covered rollers e, f, g connecting it with the cylinder a which subjects
the second material not taken off by the doffer b to a carding process and then
by means of its auxiliary cylinder g and the doffer 6 mixes it intimately with the
first material taken off by the latter and operates again upon it, whilst a heater
or fancy roller d on the one side raises the inferior material on the cylinder a

page_text: before the carding process and on the other side straightens the fibres on the
auxiliary-cylinder g.
