摘要:
A draft device (1) of a drafting machine or lap-forming machine on a spinning line comprises an opening unit (10) positioned upline of the draft unit (2). The opening unit (2) comprises opening cylinders with annular bosses or pairs of overlapping cylinders with a cylindrical helix, suitable to sink into each sliver entering the unit to open it, improving the conditions for subsequent drafting.
摘要:
A combing machine comprises a circular comb (20), a nipper (4) with lower jaw (6), upper jaw (8) and a straight comb (10). A driven shaft lower jaw nipper (30), a driven shaft upper jaw (40) rotatable with rotatory alternated motion, which supports at least one cam (42) and a transmission group (50) connected in input to a rotatable shaft with circular movement and in output to the driven shaft upper jaw (40), is provided for the movement of the nipper. The transmission group (50) comprises non-circular moving parts, to transform the circular movement into alternated rotatory movement according to a desired law of motion.
摘要:
A device (1) of a fibre manufacturing machine, such as a lap-winder, forming a lap (L), comprises a pair of calenders (22,24) to support the lap being formed, and a belt (30) which forms a circuit next to the formation area (20), in contact with the lap in formation, to limit the formation of thickening.
摘要:
The present invention relates to a device for preparing flock fibres (10) comprising an inlet pipe (12), a pair of silos (16), a pair of feeding wheels (20,22), positioned on the bottom of each silo (16), an opening wheel (40), down-line of the respective feeding wheels (20,22), a single conveyor roller (80), fed by the two opening wheels (40) by means of converging pipes.
摘要:
A feeder device (4) of a machine on a processing line preparing fibre for carding, comprising a cleaner roller (4a) and a feeder roller (4b), downline of the cleaner roller, and separation devices for separating or keeping separated the incoming flow of fibre into two or more flows of fibre to feed to the machine downline.
摘要:
A wiper group (30) for a drafting roller (20) of a textile machine, for example a combing machine, a drafting frame, a carding machine and similar, comprising an oscillating support (32) on which a rubber band (36) is mounted. The wiper group is particularly efficient at absorbing the interference on the band, of the residues accumulated on the draftin roller.
摘要:
An axial opener (8) for fibers in tufts comprising an input pipe (10), opener rollers (16,22) and a separation 5wall (42) upline of the cleaner rollers, to separate the compartments where the rollers are lodged and channel the fibers to be processed in part towards the first compartment and in part towards the second compartment of the opener.
