摘要:
An improved method for the after-treatment of washed and dried fibre cable having a minimum mass of 250 ktex by crimping, fixing, cooling and optionally cutting or tearing is achieved in that the band width of the cable issuing from the drier with a covering density of at most 5 ktex/cm is reduced by at least 50% of the original band width with a corresponding increase in the packing density, is crimped in a stuffer box crimping means at a stuffer box pressure of from 4 to 10 N/cm and a stuffer box temperature of from 80.degree. to 95.degree. C., the crimping is fixed in or immediately after the stuffer box, the cable is deposited on the surface of an air-permeable conveyor belt, air is blown or sucked there through fibre package or conveyor belt and the cable is then optionally supplied to a tearing converter or a cutting machine.
