  • Patent number: 4775421
    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.
