Abstract

In a circular loom having a machine frame, a lower and an upper running race arranged in said machine frame for guiding the shuttle, the running rollers of the shuttle are fitted between guiding surfaces of the upper and lower running race. To avoid contacting between the running rollers of the shuttle and the warp threads, the running races have thread guiding grooves crossing the guiding surfaces. The thread guiding grooves, in the running direction of the shuttle, are arranged to be inclined by an acute angle relative to the radial direction laid at the middle axis of the machine.
