Abstract
A system for replacing a filled cloth roller with an empty cloth roller for a loom is comprised of two rotatable shafts which are oppositely disposed and respectively supported by side frames of the loom. Each rotatable shaft is fixedly provided with an engaging member engageable with an end section of the cloth roller. The two rotatable shafts are automatically driven to move axially under the action of a pneumatically operated actuator, so that the engaging members are disengaged respectively from the opposite end sections of the cloth roller for the purpose of removing the filled cloth roller from the loom while engaged respectively with the same end sections for the purpose of installing the empty cloth roller to the loom. One of the rotatable shafts is driven from a loom main shaft to rotate the cloth roller, thus taking up a woven cloth on the cloth roller during the weaving operation of the loom.
