LAUFRAD FUER BANDSAEGEN

摘要

In guide rollers (2) for band saws, especially for sawing meat and bones, the contact surface (4) is very quickly fouled or soiled by greasy fat, bone meal, etc., which has a disadvantageous effect on the power transmission and the guidance of the band saw blade (3). The contact surface (4) of the guide roller rim which guides the band saw blade, is provided with open passages (7) reaching to the side surfaces (5) of the guide roller rim. Fat and other contaminating material is pressed by the band saw blade into the passages and is flung away from the rotating guide roller (2), whereby a reliable operation of the band saw is assured.
