Abstract
A method an apparatus for opening and mixing the fibers from a plurality of bales according to a predetermined mixture. The device includes tongs-like gripper means which press into the fiber bales for removing fibers therefrom. A measuring means and a control means determine the width of opening of the gripper means. A control circuit is provided for receiving a signal representing the weight of the first pick-up from a particular bale and the weight of the fibers deposited in a receiver container. When the sum of these signals is equal to the preset desired weight of the fibers that are to be deposited in the receiver container, a compared signal is produced causing the tongs on successive pick-ups to be opened to a lesser degree. As a result, a high degree of accuracy is obtained when mixing to a predetermined ratio while maintaining a high production output.
