Abstract

Described herein is a method of molding forms feed tractor belts with no prior preparation of the belting material. The belt consists of a thin forms on the outside periphery and teeth to engage a drive sprocket on the inside. The pin/tooth is molded around the belting material at equal increments corresponding with the spacing of the perforations on continuous forms.

Forms Feed Belt

Described herein is a method of molding forms feed tractor belts with no prior preparation of the belting material. The belt consists of a thin forms on the outside periphery and teeth to engage a drive sprocket on the inside. The pin/tooth is molded around the belting material at equal increments corresponding with the spacing of the perforations on continuous forms.

The material joining the pin/tooth must be a thin flexible film. It could be in strip form and joined into an endless belt or a continuous endless belt. The material must be flexible, dimensionally stable, have high tensile strength, and a high service temperature. KAPT0N* film is ideal for this application.

Referring to Figs. 1 and 2, the belt material 10 is placed into the mold and the pin/tooth 12 is molded around the belt 10. The belt material 10, being thin and flexible, will deform under the pressures of the molding process. This deformation will lock the pin/tooth 12 to prevent it from moving from its molded location. The pin/tooth 12 extends past the side of the belting material to allow the material to flow from one side of the belt material 10 to the other.

The pin/tooth 12 is molded around and encapsulating the belt materials to form an integral structure. A polymer with glass beads or fibers would be a choice material because of the wear resistance. Nylon 6/10 (60 percent glass beads) has shown success in this application.

The advantage of this design is that it eliminate...
