Abstract

The sley shaft of a loom, particularly a loom for weaving terry cloth or pile fabric, is rotated so as to provide more time for a gentle beat-up of the weft along the fabric beat-up line. For this purpose, the acceleration of the sley shaft and thus of the reed, which is connected to the sley shaft, toward the beat-up position is first faster to provide more time for the following entrainment of the weft or a group of wefts and for their beat-up by way of a discontinuous deceleration of the sley shaft and reed by a two phase deceleration toward the beat-up line. The two phase deceleration is interrupted by a slower deceleration between the two deceleration phases or by no deceleration between the two deceleration phases. Weft entrainment takes place between the two deceleration phases.
