  • Patent number: 4401217
    Abstract: A container for shipping and storing large hollow cylindrical rolls of either solid material or wound sheet material. A skid or pallet is combined with a pair of special corrugated paperboard end pads, one for each end of the roll, a pair of spaced apart anti-roll retainers extending longitudinally of and secured to the top of the pallet and between which the roll is placed, a pair of top braces extending between and interfitted with the end pads, a pair of banding straps which transversely encircle and secure together the retained roll and the anti-roll retainers, and a pair of banding straps which longitudinally encircle and secure together the pallet and end pads and top braces. The end pads and anti-roll retainers secure the retained roll from endwise shifting and sidewise rolling motion, and are constructed so that a standard sized end section is utilizable with rolls of widely varying diameters.

  • Patent number: 4264251
    Abstract: A load-retaining barrier construction formed exclusively of high tensile strength plastic sheet material having a limited stretch capability precut to length sufficient to provide the same with portions which are fixedly secured in position at opposite sides of a load confining space and with freely extending end portions which are adhesively secured together in overlapped relation, said overlapped part of the barrier being wrapped or turned upon itself about an axis extending across the width of the barrier material in the region of said overlap through a number of turns sufficient to tension the barrier to the degree desired. This tensioning is effected by a turning tool applied to the overlapped part of the barrier along said axis.
