Abstract
In a web processing device, a marking head is disposed so as to oppose an X-ray film which is trained about a print roller which is at an upstream side of slitting blades. Within a scanning range of a laser beam of a marking head, two printing regions are disposed with a non-printing region therebetween. The non-printing region is disposed so as to oppose a cutting line which is cut by the slitting blades. Before cutting the X-ray film, the web processing device forms marking patterns on both sides of the cutting line.
Claims25
A web processing method comprising:
- conveying a web along a longitudinal direction of the web in a state in which the web is trained around a plurality of rollers;
- marking at least one of characters and symbols on the web by irradiating a laser beam while scanning the laser beam;
- and
- after said marking, cutting the web at a position along a transverse direction of the web, which is orthogonal to a conveying direction of the web, while carrying out said conveying of the web.
A web processing device which, after carrying out marking processing on a web while conveying the web, carries out cutting processing on the web, said device comprising:
- a conveying device conveying the web along a longitudinal direction of the web while training the web around a plurality of rollers;
- a cutting device cutting the web by slitting blades disposed so as to oppose a predetermined position of the web in a transverse direction of the web which is being conveyed by the conveying device;
- a marking mechanism forming one of characters and symbols on the web by a laser beam emitted from a marking head at an upstream side, in a conveying direction of the web, of the slitting blades of the cutting device;
- a base portion at which the slitting blades are provided;
- a moving device moving the base portion along the transverse direction of the web;
- a supporting device supporting the marking head such that the marking head is movable along the transverse direction of the web;
- and
- a connecting device connecting the marking head, which is supported by the supporting device, to the base portion, and enabling the marking head to move integrally with the slitting blades along the transverse direction of the web.
