Abstract: There is described a device for unwindng thread by means of which the bobbin can easily rotate about the pin when a pull is exerted on the thread, but which stops the bobbin very rapidly when said pull on the thread stops, in such a way that the thread is thus no more unwound. The cross-section of the pin when considered at a right angle to the lenthwise direction thereof and the inner cross-section of the bobbin sleeve, also as considered at a right angle to the lengthwise direction thereof, at least where the sleeve and the pin engage one another, are so selected as to make possible a sidewise movement of the bobbin relating to the pin and at least where the sleeve and the pin engage one another, the one cross-section is circular while the other cross-section has a shape which is substantially different from a circular shape.

Abstract: This invention relates to an indexing supply creel of novel construction that automatically indexes either fully or partially wound packages to a winding spindle of an automatic winding machine. The supply creel construction has particular utility in handling the large packages resulting from production on open end spinning process machines.

Abstract: In a circular knitting machine, a self-balancing, circular bobbin table which has formed therein a circular groove within which a plurality of balls freely roll to dynamically balance the table as it is rotated during the knitting operations.
