Abstract
A spliced narrow non-directional endless belt for packaging applications, for use with plastic film wrapping packaging equipment. The ends of a coated fabric belt material are butted together and a splice material (also a coated fabric) is centered over the butted ends. Coatings of fluoropolymer dispersions are preferably applied over the various layers, and the entire construction is laminated together into a unitary construction. A fluoropolymer film may be positioned on the inner surface of the belt over the butted ends and over the edges of the belt onto the splice on the front surface of the belt. The resulting spliced belt is non-directional in that it is adapted to rotate in either a clockwise or counterclockwise direction when installed in the packaging equipment.
