Abstract

1,255,317. Friction crimping threads. KUGELFISCHER GEORG. SCHAFER & CO. 15 June, 1970 [20 June, 1969], No. 28801/70. Heading D1F. Continuous threads are friction crimped on apparatus comprising two friction elements each rotatably mounted on one of two mutually parallel shafts 2, 3 and each comprising at least one friction disc 4, 5 and at least one driving groove 13, 12, the discs 4, 5 being of equal diameter and the grooves 12, 13 being of equal diameter, and the spacing between the shafts 2, 3 being less than the diameter of the discs 4, 5; the apparatus also comprising a thread receiving groove 6 associated with one of the discs 4 and of the same diameter as the driving grooves 12, 13; an adjustable thread guide 9, 11 being mounted on one shaft to conduct the thread 10 from the guide groove 6 to engage the first disc 4, then the disc 5, and then to engage the grooves 12, 13 so that the thread drives the discs 4, 5. The grooves 12, 13 may be part of similar grooved elements 7, 8 having a number of grooves of different diameters to vary the crimp imparted to the thread. The elements 7, 8 are preferably releasably connected to the shafts 2, 3. In a preferred embodiment, the friction element on which the guide groove 6 is mounted comprises two friction discs. In a further embodiment, a further guide groove is positioned between these two friction discs and each element comprises two friction discs. In a further embodiment an adjustable thread guide and guide groove are provided on opposite sides of the friction element for the simultaneous crimping of two continuous threads.
