ABSTRACT:
A pressure bar for a belt grinding machine includes an elongated carrier (10) with a base plate (12) facing the grinding belt (20) and having a plurality of bores arranged in a matrix pattern, in which bores axially freely movable bolt-shaped pressure members (16) are held. The pressure members have free ends for engagement with the grinding belt (20). A plurality of positioning devices (26) are arranged next to one another in the longitudinal direction of the carrier (10) with each having a ram adjustable perpendicularly to the base plate (12) to groupwise position the pressure members (16) in their bores. Between the ends of the pressure members (16) remote from the grinding belt (20) and the rams (28) of the positioning devices (26) is arranged an elastic lamina (22) common to all of the pressure members and extending parallel to the longitudinal direction of the carrier. Each ram (28) is associated with an essentially rigid pressure piece (24) extending over the width of the lamina (22) perpendicularly to the longitudinal direction of the carrier. Each pressure piece (24) is connected with the lamina (22) and has a spacing from its neighboring pressure pieces (24) which is smaller than the diameter of one bolt-shaped pressure member (16).
