of a stuffer box wherein the polymer strips are laid on a cooling godet immediately after the stuffer box application_number US 54222306 A description in the present process a polymer material in the form of strips 10 0 5 to 1 5 mm wide and with a linear density of 250 1200 dtex is processed pa polyamide pp polypropylene hdpe high density polyethylene or lldpe linear low density polyethylene are used for example as polymeric materials the strips 10 are further processed either fed from a creel or direct on leaving the extruder for further processing four to ten strips 10 are bundled into a multifilament and thermally stretched or shrunken by up to 20 over two heating godets 11 and 12 the strips 10 are then subjected to a hot air texturing process in a stuffer box 13 wherein the strips 10 are pressed into a box and knocked against the fibre plug forming there the filaments buckle up against one another the stuffer box has a lateral inlet for a hot air texturing nozzle 21 and an air outlet zone 23 the resulting structure is thermoset while still in the box with hot air from the texturing nozzle 21 a three dimensional sawtooth shaped crimp structure forms stuffer boxes customary in the trade can be used in the process to stabilize the texturing the compressed and crimped strips 10 are taken up by a cooling godet 14 immediately after the texturing the cooled strips 10 are drawn off from the cooling godet 14 by a draw off godet 16 and fed to a spooling machine the degree of texturing is limited by the speed ratio of the cooling godet 14 to the draw off godet 16 the speed ratio of the draw off godet 16 to the second.
