Abstract
A puncher cylinder includes 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 way of the puncher knife. The holes are punched a longitudinal distance from each other essentially corresponding to the circumference of the cylinder. A system is further disclosed including the punching cylinder, as is a method utilizing the punching cylinder, and a newspaper partly produced by way of the punching cylinder.
Claims17
A printing machine comprising:
- a puncher cylinder including a puncher knife, the puncher cylinder cooperating with a paper web such that the puncher cylinder when in use can be rolled longitudinally along and in contact with the paper web, and punches holes in the paper web via the puncher knife, whereby holes are punched a longitudinal distance from each other which corresponds to a circumference of the puncher cylinder, wherein the puncher cylinder further includes a stapler, the stapler being arranged in the puncher cylinder such that staples can be placed in the paper web longitudinally essentially halfway between the punched holes when the puncher cylinder is in use;
- and
- a cutting cylinder including a cutting knife,
- wherein the printing machine is arranged such that in use, the cutting cylinder cuts the paper web through the holes, thereby forming sheets having at least two recesses.
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 including 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;
- cutting the paper web through the hole with a cut extending continuously through the entire thickness and entire width of the complete paper web, thereby forming sheets separated from each other;
- and
- folding each sheet.
A puncher cylinder comprising a puncher knife, the puncher cylinder being arranged for cooperation with a paper web such that the puncher cylinder when in use can be rolled longitudinally along and in contact with the paper web, punching holes in the paper web via the puncher knife, which holes are punched a longitudinal distance from each other essentially corresponding to a circumference of the puncher cylinder,
- wherein the puncher cylinder further includes a stapler, the stapler being arranged in the puncher cylinder such that staples can be placed in the paper web longitudinally essentially halfway between the punched holes when the puncher cylinder is in use.
