摘要:
The present invention relates to a device for the detection (1) of breaking of a fibre web comprising a number of spherical detection elements (20) held by rods (140).

The invention regards a detaching roll (11) for combing machines of textile fibres, composed of a central segment (14) of cylindrical shape, equipped with an outer surface which is scored and resistant to wear, the ends of which form a female coupling component (15) and a male coupling component (16), complementary with each other, to join all of the detaching rolls of the same combing machine into a single bar with central drive, made internally hollow and preferably as a plurality of pieces assembled together, made with light materials.
摘要:
An opening machine for separating the fibres from intermingled impurities in cotton tufts comprises a storage bin (11) into which cotton tufts to be processed are introduced, and an opening cylinder (14) associated with cleaning blades (15) for separating the impurities from the fibres and with suction openings (17, 18) for removing the impurities and the fibres separately. The opening machine (10) comprises a pre-opening roller (21) for performing a preliminary opening of the tufts. The cotton material is withdrawn from the bin (11) by feed rollers (19, 20), is processed by the pre-opening roller (21), and is introduced into a chamber (22) in the form of pre-opened tufts. A final feed roller (24) withdraws the tufts from the chamber (22) and supplies them to the opening cylinder (14). The final feed roller (24) works at a withdrawal rate greater than that of the feed rollers (19, 20) to prevent accumulation of the tufts in the chamber (22).
摘要:
A carding machine comprises a main drum (4) fed by a feed system (2) with roughly attenuated and cleaned fibres, a plurality of fixed clothed segments (40, 42), and opening cylinders or briseurs (12a, 12b) which feed the said main drum (4) at different points of the main drum. The machine (1) is characterized in that it comprises a first set of moving flats (44) which performs a first, gentle parallelization and a second set of moving flats (46) which carries out another parallelization that is more aggressive than the first.
摘要:
A fixed tube (11) of circular cross-section, which is common to several spinning stations located side by side, is connected to a suction source and has, in each station, a suction slot (15) which is located on the path of the bundle of fibres (1) and is elongate along the direction of movement thereof. Each slot (15) is enlarged in its portion (15a) which is located downstream, with reference to the direction of movement of the bundle of fibres (1).
摘要:
A fixed tube (11) of circular cross-section, which is common to several spinning stations disposed side by side, is connected to a suction source and has, in each station, a suction slot (15) arranged on the path of a bundle of fibres (1) to be compacted and along its direction of advance. A cylindrical sleeve (16) is freely rotatable on the tube (11) and has a perforated portion (17) which extends around a corresponding slot (15). The sleeve (16) is rotated about the fixed tube (11) by a pressure roller (18) which presses the bundle of fibres (1) against the perforated portion (17) of the sleeve. The sleeve cooperates with an axially stationary retaining element (9a; 25, 26, 28a) which is separate from the tube (11) and is arranged to limit the axial movements of the sleeve along the tube.
