Abstract
Apparatus and method for quickly and accurately cutting conveyor belt modules is disclosed. A guide track supports and provides a path past a cutting location for the modules that are to be cut. The modules are stopped after a selected amount of width of the module to be cut has passed the cutting location. A cutting blade which has a length extending orthogonal to the direction of travel of the modules is aligned by a die which provides a guide for the cutting blade and also accurately positions the modules prior to cutting. The blade is moved or activated by a means such as a hydraulic damped pneumatic cylinder at a controlled speed so as to cut through the modules. A cylindrical shaped anvil is located substantially across the length of the module being cut such that it provides support to the modules along a line directly opposite the length of the blade as the blade cuts through the modules. However, being cylindrical the support provided by the anvil to the module decreases from the line of support in both directions along the travel path.
