Abstract: A feed roller with clothing, the so-called taker-in (1A), feeds a first carding cylinder (3,) which presents it to a second carding cylinder (7) which rotates at greater speed than that of the first carding cylinder and which in turn presents the material to a third even faster carding cylinder (11), which in turn presents it to the doffer (13); the clothings (3A,7A,11A) of the successive cylinders are gradually thicker-set and more inclined.

Abstract: The card comprises a first-taker-in (3) and a conveying-carding roller (7), a first carding cylinder or main cylinder (9), a first doffer roller (12), a second carding cylinder (14), a second doffer roller (18) and a web removing assembly (20); at least the first carding cylinder or main cylinder (9) has its fixed carding units (10), which cooperate with its clothing, arranged around the lower periphery of the cylinder.

Abstract: A card suitable for cleaning cotton fibers and other fibrous materials is provided. The card comprises fixed carding flats adjacently disposed about a peripheral portion of a rotatable cylinder adapted to receive clothing on the surface thereof. Each of the flats comprises a group of spaced parallel blades arranged in alternate sequence with a group of distance or separator pieces and held fast thereto. The fixed carding flats are characterized by a forward end face with the spaced blades extending to the end face, the end face being disposed against the rotational direction of said cylinder. The forward end face of each of the carding flats is inclined such that the blades extending to the end face are disposed at an acute angle relative to the clothing fed to the surface of said cylinder for removal of impurities therefrom.

Abstract: A casing under vacuum located under the carding members has the suction at a position substantially central through an opening developing transversally and interesting almost the whole development of the working front; transversal clefts for the air inlet, at the two ends of the bottom wall of the casing itself, generate along the bottom wall two air blades converging towards the suction transversal opening.

Abstract: A multiple-card, so-called "tandem card" comprising, between the combing cylinder (doffer) of the first carding drum and the second carding drum, transfer means made up of doffing, carding and cleaning members which also arrange the fibres parallel to each other.

Abstract: The carding machine comprises a plurality of carding elements extending in a continuous way near a back cylinder (2), effective to rotate about its axis, and supported by supporting elements (1) which define, at the back-cylinder side, an attaching lug (3) to be engaged with a seat (4) formed in each carding element (5), which carding element consists of a plurality of carding blades or reeds arranged in an adjoining relationship and circumpherentially extending with respect to the back-cylinder (2), the inlet end portion of the carding reeds being arranged near the outlet end portion of the reeds of the carding element located on the preceding supporting element (1).

Abstract: An improved cleaning device for textile fibres is provided comprising at least one carding drum and a taker-in cylinder or drum in tangential arrangement with a lower peripheral portion of the carding drum, the taker-in drum having cooperatively associated therewith means for feeding textile fibres thereto for subsequent delivery to the carding drum for further treatment thereof. The improvement resides in employing at least a pair of first and second cleaning cylinders tangentially located at a lower peripheral portion of the taker-in drum, the first cleaning cylinder being tangentially associated with the second cylinder.
