Abstract

A device for inserting a web of printing material into a flat-bed die-cutting and/or embossing machine includes a compensator for converting a continuous movement of the web of printing material into an iterative movement of the web of printing material. A clamping unit clamps the web of printing material, a cutting unit carries out a cross cut through the web of printing material, and an inserting unit transports the web of printing material into the flat-bed die-cutting and/or embossing machine. The device advantageously allows the web of printing material to be automatically clamped, cut and fed to the flat-bed die-cutting and/or embossing machine. As a result, no further stopping of an upstream printing press is required and the amount of waste is reduced. A manufacturing system for producing packages and a method for feeding a web of printing material are also provided.

First claim

The invention claimed is:

1. A device for inserting a web of printing material, including paper or board, into a flat-bed machine for at least one of die-cutting or embossing, the device comprising:
a compensator comprising a rover, wherein the

compensator configured to convert a continuous movement of the web of printing material into an iterative movement by changing a speed of the web of printing material through changes of position of the roller;
a clamping unit configured to clamp the web of printing material;
a cutting unit configured to carry out a cross cut through the web of printing material, creating a cross out edge;
said clamping unit and said cutting unit being mutually adjacent; and
an inserting unit configured to transport the web of printing material, cross cut edge first, into the flat-bed machine for at least one of die-cutting or embossing.

2. The inserting device according to claim 1 , wherein said inserting unit includes a gripper unit configured to grip the web of printing material, at least one guide path and a drive associated with said gripper unit, said gripper unit configured to be displaced along said at least one guide path and moved by said drive.

3. The inserting device according to claim 2 , wherein said clamping unit and said gripper unit are constructed as one subassembly.

4. The inserting device according to claim 1 , which further comprises an auxiliary wind-up device for winding up the web of printing material, said auxiliary wind-up device being disposed downstream of said compensator.

5. The inserting device according to claim 1 , wherein said clamping unit, said cutting unit and said inserting unit are disposed between said compensator and the flat-bed machine for at least one of die-cutting or embossing.

6. The inserting device according to claim 1 , wherein said cutting unit includes a knife and a counter-element cooperating with said knife, said knife and said counter-element extending across a width of the web of printing material.

7. A manufacturing system for the production of packages, including paper or board packages and folding boxes, from a web of printing material, the manufacturing system comprising:
a web-fed printing press;
an inserting device disposed downstream of said web-fed printing press; and a flat-bed machine for at least one of die-cutting or embossing disposed downstream of said inserting device;
said inserting device including a compensator comprising a roller, wherein the compensator configured to convert a continuous movement of the web of printing material into an iterative movement by changing a speed of the web of printing material through changes of position of the roller, a clamping unit configured to clamp the web of printing material while being cut, a cutting unit configured to carry out a cross cut through the web of printing material, creating a cross cut edge, said clamping unit and said cutting unit being mutually adjacent, and an inserting unit configured to transport the web of printing material, cross cut edge first, into the flat-bed machine for at least one of die-cutting or embossing.
