ABSTRACT:
The metering drum for the weft thread of a weaving machine has a circumferential surface of rubber which is clamped between two supporting rings. The supporting rings may be movable axially or rotatably relative to each other so as to expand or constrict, respectively, the rubber surface in order to change the length of the thread windings. The rubber surface may also be expanded by means of a pressure medium within a chamber between two fixed supporting rings.
