Abstract: Foil stretching plant comprising a plurality of zones, more particularly a heating zone I, a stretching zone II, a stabilizing zone III and a cooling zone IV. The individual zones I, II, III and IV are designed as modules which can be installed and removed individually. Of these, at least the module designed as a stretching zone II can be installed upside down and can succeed in upside down position a first stretching zone II. In that arrangement the second stretching module can replace a stabilizing zone III.

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.
