ABSTRACT:
A textile yarn processing machine, such as a twister, spinning frame or the like, having spindle assembly stations for the processing of yarn and each including a spindle assembly for carrying a package of yarn to be withdrawn and processed and which produces a rotating balloon of the yarn around the package as it is withdrawn therefrom, and a hollow balloon restrainer device having an inside wall surrounding the package of yarn and the balloon of yarn produced for contact by the rotating balloon of yarn to limit the size thereof during such yarn processing, is provided having the following improvement. Anti-friction means forms at least a portion of the inside wall of the balloon restrainer device, preferably a plastic based sinter material, for providing a reduced coefficient of friction surface for contact by the rotating balloon of yarn processing for reducing friction damage to the yarn being processed.
