Abstract
The combing machine has at least one comber head which contains a continuously rotatable comb cylinder, a reciprocating nipper jaw unit and at least one detaching roller. The detaching roller is rotated during every revolution of the comb cylinder at first through a small angle in a backwards direction and then through a large angle in a forward direction. The rotations of the detaching rollers are produced by an electric motor which receives appropriate drive pulses fed from an electronic control unit.
Claims18
A combing head for a combing machine comprising
- a continuously rotatable comb cylinder;
- a motor for driving said comb cylinder;
- a reciprocating nipper jaw unit;
- at least one detaching roller for removing a fiber tuft from said nipper jaw unit;
- and
- at least one electric motor for rotating said detaching roller with a pilgrim step motion.
A combing machine comprising
- a plurality of detaching rollers for a plurality of combing heads disposed in longitudinally aligned manner;
- means mechanically coupling said rollers to each other;
- and
- at least one electric motor directly connected to at least one of said rollers for rotating said rollers in unison.
A combing head for a combing machine comprising
- a rotatable combing cylinder;
- means for driving said comb cylinder;
- a reciprocating nipper jaw unit;
- at least one detaching roller for removing a fiber tuft from said nipper jaw unit;
- an electric motor for rotating said detaching roller in alternating backwards and forwards direction;
- and
- an electronic control unit connected to said motor and said comb cylinder for operating said motor in synchronism with the rotation of said comb cylinder.
A combing head for a combing machine comprising
- a continuously rotatable comb cylinder;
