Rolled paper wrapping apparatus

A header heat plate for a paper roll wrapping machine comprising:

• a plurality of face plate sections that fit together to form a complete face plate, the face plate sections comprising four nearly identically shaped face plate quadrants, the face plate quadrants being individually attached to and supported by a single back plate;
• retaining means for temporarily holding a roll header to the face plate sections through the application of a vacuum suction through openings in the face plate sections;
• and
• heating means for heating each face plate section by providing an electric current to the heating means.

A header heat plate for mounting a roll header on the end of a paper roll comprising:

• a face plate having a generally planar front face, said face plate being formed from a plurality of generally identically shaped sections, each section having a plurality of vacuum holes therethrough and further including a plurality of electrically resistive heating elements cast within the header plate section, the heating elements having electrical leads extending to the exterior of the header plate section;
• a back plate having a front face connected to and supporting each of the identical sections;
• an insulation barrier mounted to a rear face of each heat plate section between the face plate and the back plate so as to contain the heat produced by the electrically resistive heating elements within the face plate;
• and
• means for mounting the header heat plate to a header plate mount of a paper roll wrapping machine.

A header heat plate for a paper roll wrapping machine wherein the header heat plate comprises:

• a face plate comprising a plurality of separate face plate sections angularly spaced about a common axis, the face plate sections being formed of molded metal and including electrical heating elements molded integrally therein, the face plate sections having exterior electrical terminals to connect the heating elements to a power supply, each face plate section including a plurality of vacuum holes therethrough for drawing a vacuum at the surface of the face plate;
• a layer of insulation behind each section of the face plate;
• and
• a common backing plate positioned behind the face plates and insulation, the face plate sections and insulation being bolted to the backing plate,
• the header heat plate assembly being attached to a header plate mount for the roll wrapping machine, the header plate mount having vacuum means for drawing a vacuum through vacuum holes formed through the back plate and insulation which are in communication with the vacuum holes in the face plate, the mount being axially movable to press the header heat plates inwardly against the ends of a roll of paper placed between a pair of opposed header plates and header plate mounts, the header heat plates retaining roll headers thereto by vacuum and heating and pressing the roll headers against the ends of the paper rolls, the roll headers having heat sensitive adhesive thereon that causes the roll headers to stick to the ends of the rolls when heated and pressed on the rolls by the header heat plates.
