20120065045 | Roller for conveying a web or sheet of paper in paper converting machines and conveying method thus obtained - An improved conveying roller for a web or a sheet in a paper converting machine comprises a first cylindrical tubular body having a plurality of radial holes arranged in substantially longitudinal rows, and a second fixed tubular body arranged coxially within the first cylindrical tubular body. The first cylindrical tubular body is capable of rotation relative to the second fixed tubular body. Slidable sealing elements are positioned between the first cylindrical body and the second fixed tubular body to define at least one suction or vacuum chamber. The chamber is suitable for being brought selectively in communication with at least one row of the radial holes during the relative rotation of the bodies. | 03-15-2012 |
20120202670 | STRUCTURE OF MULTIPURPOSE SHEET FOLDING AND STACKING MACHINE - A folding and stacking machine of a web of paper has first and second feed lines. The machine also has a folding section with folding rollers having a linear folding speed, VP. The folding rollers are adapted to receive a plurality of sheets of length L that can overlap each other for a fraction Y of their length L and to fold them into a plurality of panels P. The machine also has rollers adapted to feed at the folding speed V | 08-09-2012 |
20120245011 | STRUCTURE OF PAPER CONVERTING MACHINE - A paper converting or rewinding machine provides a cutting or perforation section, equipped with at least one blade arranged to work in combination with a stationary knife to provide the division of the web of paper into a plurality of sheets of measured length. The blade can be integral to a fixed support, or alternatively to a cutting roller that rotates about a longitudinal rotation axis. The blade(s) can be a perforation blade, or a cutting blade, with helical shape, and mounted to a perforation roller. The stationary knife can be mounted to a fixed roller. The blade performs a cutting, or perforation, of the web into sheets working in combination with the stationary knife. The blades and the stationary knifes are long substantially as the width of the paper. In particular, the blade has at least one weakened portion of determined size. | 09-27-2012 |
