Abstract
The production of pile fabrics in which the stroke of the batten of a loom during operation is periodically decreased from the value corresponding to a full stroke of the batten by a value for partial strokes which is referred to as the pre-beating distance.
Claims21
A process of producing pile fabric with pile or terry loops of constant height, on a loom having a pile-warp beam, a ground-warp beam and a batten the stroke of which in operation is shortened periodically from the value corresponding to a full beating-up of the batten by a value for partial beatings referred to as the pre-beating distance, characterized by the fact that during the weaving process the pre-beating distance is decreased or increased upon variations in the tension of the pile warp.
A loom for producing pile fabric with pile or terry loops of constant height, having a pile-warp beam, a ground-warp beam, a batten, and a feed roller for withdrawing pile-warp yarns from the pile-warp beam and having a drive device for the batten which comprises a control mechanism for shifting the beating-up position of the reed, comprising control means operatively connected to said control mechanism and activatable upon the changes of the pile-warp tension by a predetermined minimum value, by which means the control mechanism can be acted on in order to change the pre-beating distance.
