Abstract: A machine for longitudinally cutting and/or grooving continuous sheet material comprises first and second stations each of which has means for cutting and/or grooving the sheet material, the stations being spaced apart longitudinally in a direction along which the sheet material is fed through the machine, the sheet material first passing the first station and then the second station. The stations are upwardly and downwardly movable between working and inoperative positions, and a device for cutting the continuous sheet material transversely into sections is also provided. The working positions of the two stations are in a common plane along which, in operation, the sheet material is fed and each of the stations has a first guide device for guiding the sheet material, the first guide device of each station being disposed on one side of the common plane when the station is in its working position.
