Abstract
A draw texturing machine comprises a first heater for heating a yarn, a false twisting device for imparting twists to the yarn, and a cooling plate, disposed between the first heater and the false twisting device, for cooling the yarn which has been heated by the first heater and for inhibiting vibration of the yarn so as to allow the yarn to run in a stable manner. The cooling plate is provided with a yarn threading groove member having a bottom portion with which the yarn runs in contact and wall portions connected to the bottom portion to form a concave, downwardly directed opening. The wall portions of the yarn threading groove member are provided with a plurality of holes, and the bottom portion of the yarn threading groove member is provided with no holes.
Claims5
A texturing machine comprising:
- a heater for heating a yarn;
- a false twisting device for imparting twists to the yarn;
- a cooling plate disposed between said heater and said false twisting device for cooling the yarn after the yarn has been heated by the heater and for inhibiting vibration of the yarn to allow the yarn to run in a stable manner;
- said cooling plate being provided with a yarn threading groove member having a bottom portion which the yarn runs in contact with and wall portions connected to said bottom portion so as to form a concave downwardly directed opening;
- and
- wherein said wall portions of said yarn threading groove member each are provided with a plurality of holes, and said bottom portion of said yarn threading groove member is free of holes.
