Abstract
Apparatus for splicing thermoplastic coated belts is disclosed having a pair of longitudinal bars on which are respectively mounted platen heating assemblies, one bar being centrally supported pivotably on a clamping arrangement and the other bar being removably connectable with the clamping arrangement in a manner permitting pivotable positioning of the bar about one end thereof for pivotable disposition of the bars with their platens in opposed facing parallel relation at various spacings therebetween to permit uniform engagement by the bars of opposite sides of belt ends of varying thicknesses, and the clamping arrangement is adapted for bolted drawing of the bars together to grippingly retain the belt ends. The components of the apparatus are arranged for serial flow of direct electrical current through the heating assemblies and therebetween through the bars and the clamping arrangement for quick, low energy heating of the belt ends to fuse the thermoplastic material thereof. The apparatus facilitates a new belt splicing method eliminating the conventional need to use supplementary liquid thermoplastic material to effect bonding of the belt ends and thus a new belt splice is p…
