  • Patent number: 5761881
    Abstract: An apparatus for wrapping paper rolls as a roll handler to position a roll, a wrapping mechanism that applies a side wrapper, a header applicator that places a header against an end of the roll, and a pressure mechanism with one of a heated roller or a cooled roller that presses the outer portions of the header against the side of the roll. The heat or cooling and the pressure induce rapid bonding connection of the outer portions of the header with the side of the roll.

  • Patent number: 5572848
    Abstract: A header heat plate for a large paper roll wrapping machine comprising a plurality of separate face plate sections that are mounted on a common backing plate to form a complete header plate for applying a roll header to an end of a paper roll. A roll header is temporarily held to the face plate sections through the application of a vacuum suction to openings in the face plate sections. Each face plate section includes heating elements integrally molded therein. These are heated to activate a heat sensitive adhesive contained on the roll side of the roll header. A wrapping paper is applied to the roll and crimped over interior roll headers inserted at the ends of the rolls. Grooves are cut along the side edges of the wrapping paper to reduce the amount of wrapping paper overlap and indentations in the ends of the paper rolls caused thereby.
