Abstract
A combing machine having a pair of detachment rolls (6") and a nipper head (3) which, during a nip, carries out a forward stroke towards the pair of detachment rolls (6") and a return stroke. In the path of the stroke of the nipper head (3) active apparatus (26, 27, 28) is present in order to force a fiber tuft (10) into a given relative position with respect to the nipper head (3) at least at the end of the forward stroke movement.
Claims6
A combing machine comprising:
- a pair of detachment rolls and a nipper head spaced apart from the detachment rolls, the nipper head being moveable along a path toward the detachment rolls during a forward stroke of the nipper head and away from the detachment rolls during a return stroke for accomplishing a nip of a fiber tuft;
- and
- pneumatically operating forcing means adjacent a tuft clamping region of said nipper for directing an air blast towards fibers of said tuft to force said tuft in a direction towards said detachment rolls at least at an end of a forward stroke of said nipper head.
A combing machine comprising:
- a pair of detachment rolls and a nipper head spaced apart from the detachment rolls, the nipper head being movable along a path toward the detachment rolls during a forward stroke of the nipper head and away form the detachment rolls during a return stroke for accomplishing a nip of a fiber tuft;
- forcing means operative pneumatically for providing a blast of air, said forcing means being positioned on said path and being oriented toward a tuft clamping region of said nipper for arranging fibers of the tuft;
- and
- wherein said forcing means comprises a blast nozzle.
