ABSTRACT:
A belt drift control device (20) is mounted in the side wall (2a) of belt sander (1) comprises a shoulder bolt (22) threaded through a nut 21 in the side wall (2a). A generally conical, tapered roller (23) is rotatably engaged with the free end of the shoulder bolt (22). The tapered roller (23) comprises a taper portion (24) and a flange (24a). The axial movement of the tapered roller (23) is restricted by a washer (26) and a stop ring (27). A control knob (29) is fitted around the head of the shoulder bolt (22) and pressed outwardly by a compression spring (28) surrounding the shoulder bolt (22). Rotation of the control knob (29) axially feeds the shoulder bolt (22) to permit adjustment of the position of the tapered roller (23) relative to an abrasive belt (10). The tapered roller (23) is preferably positioned such that the top end of the taper portion (24) is in contact with the left edge (10a) of the abrasive belt (10) when the belt (10) is a normal position.
