Abstract

A roller cutter arrangement for a cutting wheel of a tunnel boring machine, including an interchangeable cup, a bearing block which is supported in the interchangeable cup in such a way that it is displaceable along a displacement axis, and a cutting roller unit having at least one cutting roller, which is rotatably supported in the bearing block and which acts along a working axis. The working axis is angled with respect to the displacement axis, so that cutting rollers of the cutting roller units may be situated in close proximity to one another, in particular in the central area of the cutting wheel.
