Abstract (en)
[origin: US4756142A] Apparatus for closing filled sacks, which have been transferred from a filling station to a take-over station and a closing station by a conveyor comprising a gripper, which like pliers grips the flattened lips of the filled sacks. A pair of gripping rollers, which are rotatable about axes which are at right angles to the main axis of the sack, take-over the sacks at the take-over station with the lips protruding. The apparatus also comprises a welding or sewing machine to act on the protruding lips to form a seam for closing the filled sacks. At least one of the gripping rollers is rotated as the filled sacks are conveyed to the closing machine to force the lips to protrude sufficiently to facilitate making the closing seam.
