摘要:
A lap-winder apparatus (1) on a spinning preparation line, comprises a deviation device of the webs to the lap-winder. The device comprises a final deviator (60) comprises a plurality of fixed or rotating deviation units (62) positioned on the working width of the drawing head, which form an upper abutment for the deviated web. In one embodiment variation, the device comprises an auxiliary deviator (90) comprising a plurality of rotating auxiliary rollers (92), sub-divided into two groups (92a, 92b) externally to the working width of the drawing head.
摘要:
A device (1) of a fibre processing machine, such as a lap-winder, for the formation of a lap, comprises a primary calender (22), provided with an auxiliary belt (40), and a secondary calender (24), greater in diameter than the primary calender.
摘要:
The belt (30) of a lap-forming device (1) is multilayer and has a processing layer (30a) destined to come into contact with the lap, made from polyurethane, an intermediate reinforcement layer (30b) made from polyester fabric and a dragging layer (30c) destined to come into contact with the primary calender (22), made from polyester.
摘要:
A combing machine is provided with a transmission device (30) for moving the circular comb at a variable speed. The transmission device 30 comprises a flat intermittent drive, which ensures highly reliable regular functioning.
摘要:
The present invention relates to a batt-forming machine (10) of a system for flock fibre treatment. The machine comprises two silos (16) with respective pair of feeding wheels (20,22), rotating opening wheel (40), rotating conveyor roller (80), rotating opening roller (90) and outlet opening (100), disposed down-line of the opening roller (90). The outlet openings (100) convey the processed fibre into a single joining pipe (120) for feeding the processed fibre towards subsequent processing.
摘要:
Combined device for opening and feeding flock fibres to a single carding machine, comprising a vertical silo that feeds the flock fibres to one or more clothed cylinders to open and clean the flocks, said cylinders being equipped with groups of treatment elements consisting of separating knives, sucking mouths and fixed carding sectors that purify and open the fibrous material, then taking it to a second silo that feeds it in the form of a mattress to the carding machine.
摘要:
A device for gripping the underwinding yarn for a ring spinning frame comprises a collar (14) fixed to the spindle (2), a sleeve (24) able to slide axially and a bar (40) supported by a pair of pneumatic actuators. The support axis (Z-Z) of the bar (40), defined by the points where the bar is supported by the actuators (70a,70b), intersects the active portions (42) of the bar (40) that engage with the sleeve (24) in order to stiffen the bar (40), and simultaneously open the sleeves (24) of the spindles of the spinning frame. The engagement portions (70a,70b) of the bar (40) that engage with the actuators are longitudinally separated from its active portions (42) in order to make the spinning frame compact and make the presence of the actuators compatible with the wharves (10) of the spindles (2) and with the drive means by which they are turned. The bar (40) moves vertically in order to engage/disengage the spindle (2).
