Abstract

A belt grinding machine, including a workpiece conveyor mechanism, an endless grinding belt circulating above the conveyor transversely or longitudinally of the direction of movement of the workpiece, a resilient pressure member, associated with the said grinding belt to move and hold the grinding belt against the surface of a workpiece to be ground, a plurality of double acting pressure medium-operated cylinders and pistons arranged at intervals in the direction of the grinding movement of the belt, wherein each pressure medium operated cylinder is secured by its piston rod directly to the pressure member and is provided with a duct feeding a pressure medium moving the piston to a raised position of the grinding belt, and a duct feeding a medium for moving the piston to a working position of the grinding belt, and a control valve feeding the medium for the grinding pressure to the cylinder against the lifting pressure, or evacuating the medium from the cylinder, inserted in the duct supply medium effecting the raised position of the grinding belt, said valve being connected to a senser actuating a switching and control device in dependence on the presence of a workpiece, and a timing relay operated by the said switching and control device to operate the control valve.
