Threading apparatus and threading method in a textile machine
An apparatus and method for threading a yarn onto a draw texturing machine comprising a main frame (20) provided with twisting devices (5) and second heaters (13) and a winding frame (22) provided with winding devices (10) are disposed sandwiching an operator's aisle (21) therebetween. A yarn (Y) leaving the second heater is guided along the operator's aisle to the winding device mounted on the winding frame. The second heater (13) has a yarn threading slit (13a) formed therein, and a guiding pipe (34) having a spiral cross section and yarn disengaging slit (34a) formed therein is disposed adjacent to the yarn threading slit (13a). Along the operator's aisle (21), an extendable yarn guide pipe (41) and a fourth movable yarn feed roller device (7) are disposed. A yarn feed tube (51) provided with a yarn feed nozzle (51a) is disposed between the extended end of the yarn guide pipe (41) and the winding device (10). The apparatus and method of the invention allows an operator to thread the yarn around the operator's aisle without bending.
