Abstract: In construction of an auto-doffer for weaving looms, a pair of arm mounted to a carriage carry out full automatic doffing separation by means of their three dimensional movement and a cutter unit also mounted to the carriage disconnects, in cooperation with a cloth pressor unit, a full roll held by the arms from a cloth being woven. The carriage is designed to travel along selected paths in a weaving mill to visit a loom in need of doffing operation on receipt of a command from a central processing unit. After the doffing operation, the auto-doffer carrying a full roll travels to a station aranged in the mill for transfer of the full roll to and receipt of an empty roll from a transporter which reciprocate between the station and a cloth roll stocker.
