Perforated toothed belt F N Sheppard

Hole Patterns & Shapes
Vacuum Belts provide positive holding power for very light weight products, such as paper, plastic film and fabrics. Hole size and pattern (percentage of open air) can be modified to meet the application’s need. There are endless possibilities. There are some standard patterns available, but usually each unique application requires its unique hole pattern. A simple drawing with dimensioning is all that is required to have a die made for perforating. Please contact our Technical Department.

Note: For vacuum applications, it is possible under certain circumstances, to extrude urethane timing belts with cord spacing that allows for placing the holes between cords so that the cords are not cut during perforation.
