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 combing machine envisages, between a motor (21) and a circular comb (20), a transmission device (30) having in input a motor shaft (36) with angular input speed (Win) and in output a driven shaft (19) with angular output speed (Wout), engaged with the circular comb (20). The ratio (R) between the angular output speed (Wout) and the angular input speed (Win) being defined, said ratio is variable depending on the angular position (α) of the circular comb and is between 1.55 and 0.45. In particular the ratio (R) depending on the angular position (α) is defined by the graph shown in figure 7.
摘要:
A method and device for substituting, preparing and joining the laps (1,20) in a combing machine, in which the preparation of the edge (46) of the new lap package (20) is made by holding fast said package in an unwinding position, while handling its clamped and crimped edge in a tearing manner.

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.
