Abstract
In the preparation of low friction thread for use in the manufacture of bearings the thread is first rendered bondable, is then coated in a bath of bonding resin, is led vertically out of the bath and the resin is cured to the B-stage, and the B-stage thread is wound into spools for subsequent use.

The method of making a bondable low friction thread, comprising:
- treating lengths of low friction thread to render the thread bondable by providing a thread comprised of low friction filaments intertwined with lengths of bondable filaments,
- passing the thread lengthwise through a bath of bonding resin to apply the same thereto,
- leading the thread lengthwise vertically out of the bath and while supporting it in a vertical position curing the resin on the thread to the B-stage, and
- winding the B-staged thread into spools for subsequent use.
