One rotary knife carrier of a pair of carriers in a cross cutter for running webs of paper, cardboard or the like has longitudinally extending peripheral recesses for disposable elongated strip-shaped knives each of which has a first lateral surface abutting and slidable along a supporting surface of the carrier in the respective recess, and a second lateral surface contacted by a retaining surface of an elongated clamping member which is urged against the second lateral surface by the head(s) of one or more tensioning bolts having shanks extending with clearance through openings in the clamping member and into tapped bores in the carrier. The clamping member is in form-locking frictional and/or mechanical engagement with the knife and is shiftable relative to the carrier to adjust the knife, e.g., to compensate for wear upon the cutting edge and/or to carry out adjustments relative to a complementary knife on the other carrier, against the resistance of or upon loosening of the tensioning bolt(s), preferably by one or more threaded fasteners carried by the holder and abutting an end face of the clamping member.
