Embodiment Construction

[0018] The invention will be described below using a combing machine with a suspended tong arrangement as an example. However, the invention can also advantageously be realized on combers with standing nipper arrangements.

[0019] The combing machine has a circular comb 1 rotating in the direction of the arrow, which rotates about an axis 2 and is provided with a needle row 3 on a part of its circumference. The needle row 3 has cutting strips 4 extending parallel to the circular comb, which are equipped with needles 5 . A clamping device 7 is mounted around a fixed axis 6 above the circular comb, within which a clamping jaw 9 is pivotable about an axis 8 . In addition, the feed roller pair 10 / 11 is also installed in the clamping device, and the carded lap 12 can be supplied to the jaw 13 of the clamping device through the feeding roller pair 10 / 11. The fixed comb 14 is arranged in front of the jaws. Two detaching roller pairs 15 and 16 are located behind the fixed comb. T...

Abstract

The invention relates to a combing machine comprising a circular comb (2) and an oscillating gripper device (7), the mouth of which, when swinging backwards, moves away from the circular comb thus reducing the duration and the intensity of combing. In order to counteract this, the distance of the enveloping curve (H) of the tips of the needles (5) of the circular comb from the rotational axis can be increased counter to the rotational direction of said comb. This is achieved by virtue of the fact that the increase in the distance of the mouth of the gripper from said enveloping curve, when swinging backwards, is compensated at least in part and the tuft is combed for a long, intense duration.

Description

technical field [0001] The invention relates to a combing machine with a circular comb and a gripper device which swings back and forth during the opening process. Background technique [0002] A combing machine with a circular comb, as disclosed in DE 195 04 148 A1, usually has a back and forth oscillating gripper device. The clamping device provides the combed fiber tufts to the combed sliver (combed sliver) fed back by the detaching roller when swinging forward to carry out so-called soldering (soldering), and the clamping device Keep the subsequently fed open laps in the working area of ​​the circular comb. [0003] Combers are known in which the clamping device is pivotably mounted, ie suspended, about an axis arranged above the circular comb. In other combing machines, the clamping device can be pivoted in a standing manner about an axis arranged coaxially with the circular comb or about an axis located below the circular comb. In this case, the arrangement is gener...
