A header heat plate (14) for a large paper roll wrapping machine comprising a plurality of separate face plate sections (20') that are mounted on a common backing plate (26) to form a complete header plate (14) for applying a roll header (18) to an end of a paper roll (10). A roll header (18) is temporarily held to the face plate sections through the application of a vacuum suction to openings (16) in the face plate sections (20'). Each face plate section includes heating elements (21) 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 (30) are cut along the side edges of the wrapping paper (32) to reduce the amount of wrapping paper overlap and indentations in the ends of the paper rolls caused thereby. |
