Abstract
A comber has a nipper head (3), detaching rolls (6), and half-lap (4), wherein, during a combing cycle, the nipper head (3) and the detaching rolls (6) are moved by a drive system (31 to 40) out of a rear end position relative to one another into a front end position and back again. The detaching rolls (6) are driven in a pull-off direction (25) of a combed tuft (11). The half-lap (4) is also driven. The nipper head (3) comes within an area of action of a needle segment (5) of the half-lap (4) during a section of the combing cycle. To increase performance, provision is made for the drive system (31 to 40) to rotate the half-lap (4) during a combing cycle by an integral number of rotations, at least twice. The length of the needle segment (5) is extended in the direction of rotation in accordance with a higher rotational speed.
