Cloth roll exchange apparatus for a loom.

摘要

A full roll (4B) transferred from a cloth wind-up position (P1) in a weaving machine to a temporary full-roll storage position (P3) on a transfer carriage (13) is prevented from rotation by meshing with a gear mounted stationarily. The transfer carriage (13) is equipped with empty roll supporting arms (16A; 16B) and cutter supporting arms (17A; 17B) having free ends at which a cloth cutting mechanism (19) is supported. An empty roll (4A) is supported by hands (16a) mounted at free ends of the empty roll supporting arms (16A; 16B) so as to be rotated by an empty roll driving motor (18). Owing to rotation of the empty roll (4A), tension is applied to a cloth between the full roll (4B) and the empty roll (4A) so that it is cut by the cloth cutting mechanism (19) in a tensioned stationary state. <IMAGE>
