ERNEST DE PASS, of the Office for British and Foreign Patents, 6S, Fleet Street,
in the City of London, Patent Agent. "IMPROVEMENTS IN COMBING MACHINES."
A communication from abroad by Joseph Imbs, of 17, Boulevard Saint-Martin,
Paris, France, Engineer.
This Invention has for its object a new contrivance by means of which the
double combing of fibrous materials is effected when necessary, and which
contrivance the communicator calls a combined double combing machine (peigneuse-
double accouplée).
It is sometimes requisite to comb twice, and after the exit of the fibrous material
from the first combing-machine, it is necessary to pass the material through
drawing-frames and lap-frames, or other preparatory machine, to again give it the
regular form suitable for feeding a second combing machine.
This result is now obtained by simplifying the operations in the following
manner.
1. The superposition or consolidation in the first combing machine is effected at
very short intervals, and instead of obtaining a thin carded sheet, which by passing
through a funnel becomes converted into a sliver, as is usually the case, a fleece of
any desired thickness, perfectly regular, and one which can be rolled for its whole
width, so as to be carried direct to the second combing machine, without any
intervening operation is obtained.
. In combining or coupling together or placing on the same framework the two
successive combing machines, each of which comprises all its working parts, but the
first only containing the delivery or payingout rollers for the rough wool to be
combed, and the second the apparatus for converting the sheet, resulting from the
second superposition or consolidation into a sliver, also the can for receiving such
sliver.
The Gist combing machine thus makes the thick flecce hereinbefore referred to,
and this fleece passes direct into the nipper or feeding device of the second combing
inachine without manual labour of any kind.
It is this which the communicator calls a combined double combing machine.

page_text: When this new contrivance is applied to an Imbs combing machine it is preferred
to effect the superposition or consolidation in the first combing machine, on the
brush, or on the completely circular and velvet faced roller used in such machines,
and it is further preferred to effect this superposition or consolidation below such
brush or such roller, that is to say, on its lower face. The combed sliver being
thus laid upon such roller with its head forward, but the progressive rotation of the
oscillating roller being in the direction of the tails of such sliver, the result is that
the fleece thus formed contains filaments laid in a direction opposite to that which
they have in the primitive fleece, and present themselves to the second combing-
machine with their tail ends forward. In the second combing-machine the
filaments have therefore their tail ends submitted to the same action as that which
their head had received in the first combing machine, and reciprocally.
