ABSTRACT:
A full roll transferred from a cloth wind-up position in a weaving machine to a temporary full-roll storage position on a transfer carriage is prevented from rotation by meshing with a gear mounted stationarily. The transfer carriage is equipped with empty roll supporting arms and cutter supporting arms having free ends at which a cloth cutting mechanism is supported. An empty roll is supported by a holding device mounted at free ends of the empty roll supporting arms so as to be rotated by an empty roll driving motor. Owing to rotation of the empty roll, tension is applied to a cloth between the full roll and the empty roll so that it is cut by the cloth cutting mechanism in a tensioned stationary state.
