AN ARRANGEMNT FOR CONDENSING A FIBRE STRAND DRAFTED IN A DRAFTING APPARATUS OF A RING SPINNING MACHINE

摘要

Apparatus for condensing a drafted fibre strand when leaving a pair of delivery rollers of a grafting unit comprising a condensing zone following the pair of delivery rollers, comprising a sliding surface arranged in the condensing zone and provided with a suction slit substantially extending in transport direction of the fibre strand on which sliding surface slides an air permeable transport belt driven by means of a roller and transporting the fibre strand, and comprising a clamping roller for the fibre strand leaving the condensing zone, characterized by means for drivably connecting the roller (25), which drives the transport belt (20,29), to the pair (8) of delivery rollers of the drafting unit (1).
