A doffing/donning apparatus is used in combination with a row of winders each of which winds filamentary material upon a tube carried by a rotary spindle of the winder to form a package. A tube exchange arm is mounted for up-and-down movement and is alignable with the spindle so that a tube on the tube exchange arm can be transferred to the spindle. The tube exchange arm comprises a rotary cylinder having inwardly projecting bristles. The cylinder is telescoped onto the tube while being rotated so that the bristles deflect tangentially to grip the tube. |
