Abstract

Synthetic filament processing apparatus comprises first and second filament advancing means between which the filaments are drawn by operating the second advancing means at a greater filament advancing speed than the first advancing means, one or each of the advancing means comprising a pair of positively driven rollers around which the filaments pass in loops and a heater positioned between the rollers and contacted by at least some of the filament loops. In Fig. 1, the undrawn filaments 11 are first taken round driven feed rollers 1 and 2, also contacting a shoe type heater 3 between the two rollers. The filaments are then drawn over an additional heating plate 4 and are taken round driven draw rollers 5 and 6, also contacting a shoe type heater 7. Preferably, the feed rollers 1 and 2 are cylindrical, and the draw rollers 5 and 6 each have a tapered portion 9 to allow relaxation of the filaments. The draw rollers 5 and 6 may alternatively be cylindrical or stepped. The roller axes of each pair are inclined, and the rollers of each pair are driven from a single drive shaft by means of belts and pulleys (Fig. 4, not shown). After heating the filaments with heater 7, cooling may be effected by. (i) making rollers 5 and 6 longer than the heater 7 so that the filaments move out of contact with the heater, or (ii) passing the filaments round a pair of unheated rollers. The feed and draw rollers may be spaced from the heaters, and heat insulation may be applied to the ends of the heaters. Exemplified materials are polyester and nylon 6À6.
