Abstract
A cutter machine has cutter heads or rollers rotatably mounted on a pivoting cutter arm. It also has a loading ramp and a conveyor running in a direction towards the work face of the cutter machine to take up and convey away cut material. The cutter arm is mounted on a sliding carriage which is displaceable along guides running in the longitudinal direction of the machine. The carriage is configured as a self-supporting box profile in a clear cross-section space of which a removal conveyor is mounted so that it may slide. For this reason, the cutter machine is particularly well-suited for use in small seam heights and for particularly low constructional design. It may nonetheless be used satisfactorily for operating reliably over a variable tunnel width.
