Textile machinery with a focusing device

摘要

The present invention relates to a device for focusing the sliver (V) in the spinning machine, the sliver (V), from the exit roller pair of the drafting device unit (2) (7, 8) is supplied with suction air and drive has been a subsequent focusing element rotates (17), is sent to a guide surface having a suction effect of the suction zone (Z), the focusing elements (17), following the suction zone (Z), rotatably supported at least one nip roller (33) is, in order to form a nip line (P), are disposed, an apparatus. To attach already later focusing device for spinning machinery present, conventionally, the additional costly drive means are provided, also for arrangement of such a device, partially very time takes, it takes a long and thus extremely high cost. To eliminate these drawbacks, an apparatus according to the present invention, the A focusing elements (17) and said nip roller (33), which is rotatably supported on a common carrier (20), the holding member (20) is attached removably to the spinning machine using a fixing means (46), the opening The focusing elements having a (17) has at least one drive element (28), the drive element (28), upon movement of the focusing elements from the rest position to the operating position (17), pressing device (55, 58) via a drive coupling portion is formed with the lower roller (7) of the outlet roller pair (7, 8), said carrier in this case (20), the said focusing element (17) has a suction passage (SK) for the suction air, a first end of the suction passage (SK) is (S1), the be connected to the focusing element (17), said suction passage (SK) a second end (S2) is, they terminate in the region of the holding body (20), in the region of the holding body (20) the retaining body (20), the spun in its attached position And it is fixed to the 械.
