Patent DE-19909380-A1 (DE)
Title: Heat exchanger for yarn texturizing process has yarn passages enlarged for yarn laying and slower yarn movement system at start and accelerating to operating speeds to prevent yarn breaks
Inventor: WABRA GUENTER
IPC: D02G1/16
Filed: 1999-03-04
Abstract: To feed and lay a yarn in a false twisting texturizing unit, the feed has a heat exchanger (1) containing a fluid and at least two yarn passages (4-6) which are enlarged to lay the yarn.  The yarn is led through the passages (4-6) by an auxiliary carrier air flow in a suction and/or blowing action. The yarn can also be drawn through the passages (4-6) by a bodkin. For laying the yarn, the passages (4-6) are separated in the axial and/or radial direction, and then closed when the yarn is in position. To seal the heat exchanger (1), a further fluid stream and especially of air at the passages (4-6) keeps the first fluid stream from the passages (4-6). The flow of the first and/or second fluid flows is interrupted before the yarn is laid or the heat exchanger (1) is opened, and the fluid is extracted from the heat exchanger (1). After the yarn has been laid, it is moved initially at a slow speed and then accelerated to the operating speed level. An Independent claim is included for a false twisting texturizing apparatus where the heat exchanger (1) is divided along its length into two parts (2,3) which can be separated to lay the yarn.  Preferred Features: An injector jet to feed the yarn is before and/or after the yarn passages (4-6) at the inlet passage (4) and/or the outlet passage (5). The yarn inlet passage (4) and the outlet passage (5) are linked to a tube with openings especially in a radial direction. The yarn passages (4-6) are composed of separate moving segments (7,8), to open the passages (4-6) in an axial and/or radial direction to lay the yarn. The segments (7,8) can be separated from each other, rotate to each other on an arc of the passages (4-6), and are in succession in the yarn movement direction. At least one segment (7,8) is pressed against a neighboring segment by a spring (9). At least the zone in the heat exchanger (1) filled with the first fluid is sealed with a seal (10,11). The fluid flow through the heat exchanger (1) is against the direction of yarn travel. The yarn passages (4-16) are at the yarn inlet (5) and outlet (6) passages. The yarn passage (4-6) has a chamfer to thread the yarn through. The yarn passage (4-6) structure is wear-resistant. The heat exchanger (1) is locked by an electrical, hydraulic and/or pneumatic system. The fluid in the heat exchanger (1) is water, saturated with a brightener, and is at a given temp. A further fluid flow, and preferably air at a pressure of 0.5 bar, is at the yarn passages (4-6) to seal the heat exchanger (1) and/or dry the yarn. The heat exchanger (1) has a variable length, and is especially in a telescopic structure.
