Problems solved by technology

[0010] In particular, it has been observed that if a large amount of fiber is supplied to the opener, the output tow is still contaminated and very disordered, an undesirable situation which does not allow good downstream further processing

Embodiment Construction

[0021] Referring to the drawings, reference numeral 1 generally indicates an assembly for processing fiber bundles, which forms part of a fiber processing line, in particular a carding preparation line.

[0022] The assembly 1 comprises a feed pipe 2 for conveying fibers F to be processed, for example fibers from a loosening machine.

[0023] The supply pipe 2 is arranged at a predetermined height from the ground plane T, extending along a substantially rectilinear supply axis A, preferably parallel to the ground plane T. As shown in FIG.

[0024] The assembly 1 also comprises feeding means 4 adapted to separate the dust-laden air from the fibers, preferably for feeding fiber bundles downstream. In particular, the feeding device 4 is adapted to deviate the fibers in the feeding direction downstream V, eg vertically and perpendicular to the ground plane T (and thus preferably perpendicular to the feeding axis A).

[0025] Preferably, the module 1 comprises a separator device 6...

Abstract

The invention provides an opener for fibre in tufts on a carding preparation line and the opener for fibre comprises a first opener roller (32) and a second opener roller (52) beside the first. The first opener roller (32) is fed by a two transversally separate fibre flows (Fl,F2), which proceed axially towards the ends of the first roller, passing then onto the second roller and proceeding axially towards the centre thereof, from where they are expelled. The opener roller (32, 52) has portions fitted with pegs positioned along axially symmetric, respective imaginary helical lines.

Description

technical field [0001] The invention relates to an opener for processing fiber bundles on a carding preparation line (carding preparation line, carding pretreatment production line). Background technique [0002] As is known, obtaining textile yarns from fibers requires multiple treatments of the fibers in order to remove impurities and dirt from the fibers, to align the fibers and to draft them. Such treatment produces a fiber web (fibre web) which is subsequently processed, for example on a drafting machine, to obtain yarns. [0003] This treatment is carried out on different machines, where, for best results, it is repeated several times in a gradual and thorough manner. [0004] Specifically, on the schematic fiber processing line, a picker removes fibers from bales so that fiber bundles can be obtained by airflow. [0005] The tow will then be processed in a device for removing impurities such as those crushed stones or non-ferrous materials mixed in the tow, which un...
