ABSTRACT:
A blowing device for a belt grinding machine has a nozzle arrangement having nozzles positioned relative to its grinding belt for blowing cleaning air jets onto the circulating grinding belt. The device further has an oscillating drive to oscillate the nozzle arrangement in the longitudinal direction thereof. A pair of elastic members suspend the nozzle arrangement, which is oscillated in the longitudinal direction by using a magnetic field. A ferromagnetic member is connected to the nozzle arrangement and is positioned within the magnetic field produced by an electric coil. By varying the magnetic field, the nozzle arrangement can be moved in the longitudinal direction, the spring providing an elastic restoring force to move the nozzle arrangement is the opposite direction when the magnetic field is turned off.
