Abstract

A tensioning machine for the continuous treatment of a length of textile material comprises a pair of moving conveyor devices having parallel runs provided with a plurality of grippers. A mechanism for closing the grippers is provided at the inlet end of the conveyor runs and a mechanism for opening the grippers is provided at the outlet end of the conveyor runs. Each of the mechanisms includes a moving actuating device which is driven synchronously with the conveyors and moves in the same direction and at the same speed as the grippers. The tensioning machine is particularly suitable for comparatively high conveying speeds.
