ABSTRACT:
Strand lap-ups may be removed from textile rolls by using the present method and apparatus while the textile rolls remain in position on the textile machine or by initially removing a roll with a lap-up thereon from the textile machine before shearing and severing the lap-up and replacing the removed roll with another roll free of any lap-ups. The present apparatus includes a wheeled hand truck with a vertical array of spaced shelves with at least one of the shelves containing replacement textile rolls and another shelf serving to receive textile rolls having lap-ups thereon. An electrically powered shear is associated with the hand truck and includes a pair of generally parallel cooperating rows of teeth facing in a common direction with the free ends of the teeth being blunt to prevent damage to the roll when being utilized to remove the lap-up from the roll. A battery and battery charger are carried by lower regions of the hand truck and the hand truck is dimensioned to easily maneuver down relatively narrow aisles between rows of adjacent textile machines in a textile mill.
