Abstract

On a machine frame, a machine for the lengthwise treatment of webs of corrugated board comprises a pair of tool beds, on which several tool holders are disposed for displacement by means of a threaded spindle. The tool holders each support a tool. The number of tool holders exceeds the number of threaded spindles. Each tool holder has a spindle nut, which is disposed on the threaded spindle and is mounted rotatably in the tool holder. It can be non-rotatably coupled with the tool holder by means of a clutch.
