Description

The invention relates to a laminating machine and to a method of laminating a material.

By the WO 2015/147262 A1 a device is known in which the individual sheets are arranged scaled and provided together with an additional layer.

By the DE 10 2010 037 592 A1 is a laminating machine with sheet feeder known. It is disclosed to either separate the sheets or to arrange them scaled. Depending on this, a corresponding material web is then generated.

By the EP 2 383 117 A1 is a laminating machine with sheet feeder known. It is disclosed to arrange the bows either bumped or scaly. Depending on this, a corresponding material web is then generated.

By the EP 0 586 642 B1 is a laminating machine with sheet feeder known. It is disclosed to either separate the bows or to place them in shingles or shingles. Depending on this, a corresponding material web is then generated.

The invention has for its object to provide a laminating machine and a method for laminating sheets of a material.

The object is achieved by the features of claim 1 and the features of claim 9.

One advantage is in particular that sections of a material web can be separated in a particularly simple, precise and fast manner without incurring waste in a running operation, which would increase the risk of disruption of the processing machine. The precision is preferably supported by two clamping devices and optionally a single orientation of sheets.

An advantage, for example, is that a particularly fast and low-interference lamination operation is made possible. This is achieved, for example, by web-shaped lamination material and more preferably by roll changers for unwinding the lamination material. In particular, start-up of a lamination operation is facilitated when a lamination disposal apparatus is disposed, for example, because production can be started easily and quickly without manually removing lamination material which is difficult to access.

One advantage, for example, is that a particularly high degree of precision in the application of the laminating substance can be achieved. This is achieved for example by Bahnkantenausrichter and / or a web tension control in the supply of the lamination. Alternatively or additionally, a particularly precise alignment of sheets to be laminated takes place, for example, by singling and / or aligning the sheets and / or scaly arrangement of the sheets relative to each other.

One advantage, for example, is that lamination of sheets can be particularly precise and that the sheets or sections are not damaged in the process, for example by attacking knives or incomplete lamination.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.
