A printing machine including:
- a puncher cylinder comprising a puncher knife, the cylinder being arranged for cooperation with a paper web such that the cylinder when in use can be rolled longitudinally along and in contact with the paper web, punching holes in the paper web by means of the puncher knife, which holes are punched a longitudinal distance from each other essentially corresponding to the circumference of the cylinder;
- and
- a cutting cylinder comprising a cutting knife,
- wherein the cutting cylinder is arranged to cut the paper web through the holes.
A method of punching holes in a paper web, the method comprising:
- allowing a longitudinally moving paper web to pass between and being pressed between two opposing and revolving cylinders, one of the two cylinders being a puncher cylinder comprising a puncher knife and the other of the two cylinders being an opposing cylinder;
- punching a hole in the paper web by means of the puncher knife where the moving paper web is pressed between the two cylinders with each revolution of the puncher cylinder;
- and
- cutting the paper web through the hole.
