Embodiment Construction
[0030] figure 1 A known clamp unit (referred to simply as "clamp") pivotally mounted on the crank arms 2, 3 is depicted. Furthermore, two crank arms 2 are each pivotably mounted on one side of the circular comb shaft 5 of the circular comb 4 . The circular comb 4 has a comb segment 7 on part of its circumference. The other end of the crank arm 2 is rotatably attached to the nipper mount 8 . The rear pivot arm 3 (there may be two on site) is rigidly attached to the nipper shaft 10 . The opposite free end of the pivot arm 3 is rotatably connected to the nipper mount 8 by means of a shaft 9 . Usually, a plurality of combing heads are arranged side by side on the combing machine, wherein each combing head has a nipper unit. However, in the example, the bridge according to the invention is only depicted and described attached to a single clamping unit.
[0031] The pliers 1 basically consist of a lower nipper 12 firmly attached to the nipper mount 8 and an upper nipper 14 (som...

The invention relates to a clamping assembly (1) of a combing machine, comprising a lower clamping plate (12), which can form a clamping point (KO, KU) in the region of the lower clamping plate clamping lip (30) together with an upper clamping plate (14) that is movably mounted in the clamping assembly, comprising a feed roller (27) that is rotatably attached within the clamping assembly (1) above the lower clamping plate (12), wherein at least one detaching roller (24a, 24b, 22) that is mounted in the machine frame (MS) for forming a detaching clamping line (K, K1) is arranged downstream of the clamping assembly (1), and comprising a connecting piece (32) which is fixed between the feed roller (27) and the clamping lip (30) on the lower clamping plate (12) in a removable manner and which is oriented transverse to the conveying direction (F) of the fiber mass (W). A rotatably mounted circular comb (4, 4A) is arranged below the lower clamping plate (12) in order to comb out fiber tufts (FB). The aim of the invention is to design the connecting piece such that the connecting piece can be mounted and removed quickly and without special aids and such that an optimal contact to the lower clamping plate is ensured along the entire length of the connecting piece. This is achieved in that the connecting piece (32) has magnetic means (50) in the region of the connecting piece contact surface (SU) that faces a contact surface AF of a lower clamping plate (12) consisting at least partially of ferromagnetic material, and means (54, 60) are provided in the region of the two ends of the connecting piece (32), said connecting piece being fixed on the lower clamping plate (12) on the contact surface (AF) plane in a formfitting manner via said means.
Description
technical field [0001] The invention relates to a nipper unit of a combing machine, the nipper unit has a lower nipper and a feed roller, the lower nipper and an upper nipper movably mounted in the nipper unit can be clamped on the lower nipper A nip point is formed in the region of the lip, said feed roller being attached rotatably above the lower nipper in a combing unit, wherein at least one detaching roller is inserted behind the combing unit, said detaching roller being mounted on a frame For forming the separation nip line, and a bridge is removably attached between the supply roller and the nipper lip, and the bridge is oriented transversely to the conveying direction of the fiber body, wherein a fiber tuft for combing out is arranged under the lower nipper Rotatably mounted round comb for fleece. Background technique [0002] In actual practice, the portion to be combed (also called "noil") needs to be adjusted on the comber as required. The noil fraction ranges fr...
