Abstract
A condensing zone is arranged downstream of the main drafting area of a drafting assembly of a ring spinning machine, which condensing zone is defined on one side by a front roller pair of the drafting assembly and on the other side by a nipping roller which presses a drafted fiber strand against a supporting surface. The peripheral speed of the nipping roller is from 3% to 8% greater than the peripheral speed of the front roller pair. The fiber strand to be condensed obtains thus a lasting draft in the condensing zone.
Claims28
An arrangement for a spinning machine comprising:
- a front roller pair ending a main drafting zone of a drafting assembly, and
- a condensing zone downstream of the front roller pair, which condensing zone bundles a drafted fiber strand and which condensing zone is ended by a driven nipping roller which presses the fiber strand against a supporting surface wherein the peripheral speed of the nipping roller is between 3% and 8% greater than the peripheral speed of the front roller pair to thereby draft the fiber strand in the condensing zone by a factor of between 3% and 8%.
An arrangement for a ring spinning machine comprising:
- a front roller pair ending a main drafting zone of a drafting assembly, and
- a condensing zone downstream of the front roller pair, which condensing zone bundles a drafted fiber strand and which condensing zone is ended by a driven nipping roller which presses the fiber strand against a supporting surface,
- wherein the condensing zone includes a sieve belt which in use transports the fiber strand over a sliding surface with a suction slit, and
- wherein the sieve belt is smoother on its side facing the sliding surface than on its side facing away from the sliding surface.
