摘要:
Associated with the main cylinder (5) of the first card (C1) is a first stripper or doffer cylinder (9), and associated with the second main cylinder (11) of the second card (C2) is a second stripper or doffer cylinder (17) in turn associated with a web removing assembly (19); the first stripper or doffer cylinder (9) of the first card works with the second main cylinder (11) also, rotating more slowly than but in the same direction as the two main cylinders (5, 11), and a stripper/feed cylinder (15) is provided to interact simultaneously with said doffer (9) and with the second main cylinder (11), rotating in the opposite direction to these, as a result of which the material originating from the first main cylinder (5) is yielded by the first doffer (9) in part directly with carding action to the second main cylinder (11) and in part to said stripper/feed cylinder (15) and by the latter to said second main cylinder (11).
摘要:
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).
摘要:
The draw group - combined with the card - comprises several pairs of rotating cylinders (7,9), both the cylinders of each pair being driven into rotation to drag the web (B) passing therebetween; the cylinders (7,9) of a subsequent pair are provided with a peripheral speed greater than that of the cylinders (7,9) of the preceding pair, in order to cause a partial draw; the cylinders of adjacent pairs graze one another thus obtaining a self-cleaning effect; the two cylinders (7,9) of each pair are provided with metal surfaces and one of them is elastically urged towards the other.
摘要:
A casing (12) under vacuum located under the carding members (3, 5, 7) has the suction at a position more or less central through an opening (30) developing transversally and almost according to the whole development of the working front; transversal clefts (22) for the air inlet, at the two ends of the bottom wall of the casing itself, generate along the bottom wall (14) two air foils or blades converging towards the suction transversal central opening.
摘要:
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.
摘要:
A multiple-card, so-called "tandem card" comprising, between the combing cylinder (doffer) (5) of the first carding drum (3) and the second carding drum (7), transfer means made up of doffing, carding and cleaning members (14, 14A, 14B, 14C) which also arrange the fibres parallel to each other.
摘要:
A stripping roller (19) for drawing fibres (11A) from a tops or feeding sliver (11) for open-end spinners, in which the teeth, which are circumferentially out-of-alignment, are formed on the outer periphery of laminar flexible rings (50) mounted uniformly spaced apart by spacers which have constant thickness and which are deformed with respect to the planar shape, i.e. "twisted" by means of two annular end elements provided with facing complementary shaped surfaces, the rings having inclined drawing teeth, i.e. hooking teeth which are alternated with discharging teeth having opposite inclined profile.
