ABSTRACT:
A guiding and pressing device for a belt sander includes two triangular guiding blocks or sheet-like inclined guiding blocks, which are disposed at suitable positions on a front side frame of the sander and near to a circulating path of a sand belt. The two guiding blocks have opposite inclined surfaces near an edge of the sand belt to restrict the circulating path of the sand belt without damaging the edge of the sand belt. In addition, an elastic pressing or push rod is disposed inside the sand belt and on a backside of the frame in order to frequently push the sand belt outwards and thus to keep the sand belt in a tightened state when the belt sander is sanding.
