Abstract (en)

[origin: DE4436154C1] A machine is disclosed for trimming the sides of building blocks or the like, in particular dried green bricks (Z) or baked bricks (Z) that are centred, vertically clamped and thus conveyed through at least one trimming station with laterally arranged tools. The invention is characterised by a transport device with two endless belts under compression load made of flexible material and designed as conveyor and compression belts (2, 3). The conveyor and compression belts (2, 3) are forcibly guided in the lateral position by at least one groove and spring connection (7a, 8), in particular a keyway and V-rib connection, and run on a rail- or plate-shaped flat support (9) at least in the area of the trimming tools (5).
