Abstract
A method and device for continuously grinding the teeth of a number of adjacent saw bands using a rotating grinding wheel which is reciprocatingly moveable in a direction transverse to the longitudinal direction of the saw bands. The method comprising lowering the grinding wheel at the start of each reciprocating grinding movement a predetermined distance which corresponds to wear the grinding wheel experienced in the prior grinding cycle. As the grinding wheel is moved towards the band material, it is acted on by a stationary abrasing wheel which reshapes the grinding wheel. During the return stroke of the grinding wheel the saw band blanks are advanced and repositioned for another cycle of the grinding wheel.

Method of continuously grinding the teeth of a number of adjacent saw bands out of the total band material, by a rotating, grinding wheel, reciprocatingly movable transversely to the longitudinal direction of the saw bands, said method comprising:
- adjusting the position of the grinding wheel, at the beginning of every reciprocating grinding movement, a predetermined amount corresponding to the wear of the grinding wheel after one grinding cycle;
- passing the grinding wheel on its way towards the band material by a stationary abrasing wheel for the re-shaping of the grinding wheel;
- effecting step-by-step movement of the saw bands by the return stroke of the grinding wheel to its initial position, after the second passage of the grinding wheel past the saw bands, whereby the grinding wheel once more passes the abrasing wheel.
