Abstract: A conversion unit converting a first continuous web substrate into a second substrate in the form of converted blanks of predetermined length. On account of cutting tool rotation speed, the web moves at various speeds for cutting the web cut lengths and other aspects of cutting and transport process having a constant input speed. The unit includes a first motorized arrangement for producing a first run driving of the web, a sheeter having rotary tools for cutting the web into blanks, a second motorized arrangement for producing a second run driving of the substrate, the second arrangement being positioned in the immediate proximity of the sheeter, and at least one station having rotary tools for converting the blanks.

Abstract: A conversion unit converting a first continuous web substrate (2) into a second substrate in the form of converted blanks of predetermined length (3). On account of cutting tool rotation speed, the web (2) moves at various speeds for cutting the web cut lengths and other aspects of cutting and transport process having a constant input speed. The unit includes a first motorized arrangement (4) for producing a first run driving (F) of the web (2), a sheeter (12) having rotary tools (13, 14) for cutting the web into blanks (3), a second motorized arrangement (17) for producing a second run driving of the substrate (2, 3), the second arrangement being positioned in the immediate proximity of the sheeter (12), and at least one station (21, 22, 23) having rotary tools (26, 27, 28, 29, 32, 33) for converting the blanks (3).

Abstract: To adjust peripheral register of engraved cylinders, the positions of a respective angular register mark arranged on each cylinder is measured with respect to a zero reference, and an angular printing mark characteristic of the position of the engraving is associated with each cylinder. The data of the job to be run are stored. The respective angular displacements of the engraved cylinders are indexed with respect to a reference cylinder in accordance with the job. By determining the web length separating two printing points of two successive engraved cylinders, this length is divided by the peripheral length of the cylinder and the remaining amount of the division is used for determining the angular indexing. Each cylinder is then brought into its angular indexed position, is first disconnected from a common transmission, and then all the cylinders are simultaneously reconnected to the transmission.
