ABSTRACT:
A compact machine for measuring, cutting and applying insulation blanket material onto sheet metal workpieces as they flow along a conveyorized lower line. The blanket material flows along an upper path. A flying shear mechanism, which travels a short distance along this path, is driven downstream when the trailing edge of a workpiece is sensed. Rack and sector mechanism brings the shear to an incisive stop at its downstream cutting position when the shear blade strikes its cutting block; hence the kinetic energy of the downstream movement is utilized for shearing. The shear remains in downstream position, to serve as a gage for starting the blanket material, until a sensor in the lower flow path senses the leading edge of the next sheet metal workpiece; this raises the shear blade and moves the shear mechanism to upstream position. A pneumatic system accurately times the cut-off mechanism to match the shearing of the blanket material to the length of the workpiece, leaving a margin if desired.
