Abstract
An apparatus for replacing a full cloth roll loaded on a pair of rollers of a weaving machine with an empty cloth roll, which apparatus includes a pair of oscillating members supported by the weaving machine to oscillate about an axis of a rod supported by the weaving machine and cylinders for having both the oscillating members to produce oscillating movement. Each oscillating member includes a contact portion exerting a pressing force to the full cloth roll to roll the full cloth roll while both the oscillating members are oscillating in one direction. Each oscillating member further includes a guide wall disposed behind the contact portion for catching the empty cloth roll in cooperation with the peripheral surface of the textile of the full cloth roll, and for directing, during the oscillating movement of both the oscillating members, the empty cloth roll to the upper position right above both the rollers in cooperation with the peripheral surface of the textile of the full cloth roll.
