Techniques for processing a web with a laser are provided. In an example, an apparatus for processing web material can include multiple processing stages and a laser assembly. Each of the multiple processing stages can be configured to process a moving web of material along a web path. The laser assembly can be configured to process the moving web of material with a laser at a first stage of the multiple stages. The laser assembly can include a laser configured to generate a laser beam, a gimble assembly configured to direct the laser beam along a cut path at a position of a web path of the moving web of material, and a servo driven mirror assembly configured to provide an adjustable field of view for the laser stage at the position of the web path.

A supply device (3) for supplying substrate strips (10, 10′; 11, 11′) to a double-belt press (2) for pressing the substrate strips (10, 10′; 11, 11′) together includes unwinding stations (4, 5) each having an unwinding shaft (6, 7) for receiving a substrate strip roll (8, 9) and serving to unwind the substrate strips (10, 10′; 11, 11′) from the substrate strip roll (8, 9), at least one of the unwinding stations (4) having a force-measuring device with a measuring shaft (16, 17) around which one of the substrate strips (10, 10′; 11, 11′) can be wrapped, an auxiliary shaft (18, 19) being assigned to the measuring shaft, wherein the auxiliary shaft (18, 19) and the measuring shaft (16, 17) of the unwinding station (4) are moveable relative to each other between a guiding position for guiding the substrate strip (10, 10′; 11, 11′) from the roll of the substrate strip rolls (8, 9) through a gap between the measuring shaft (16, 17) and the auxiliary shaft (18, 19) and an operating position defining a pre-defined and/or pre-definable wrap angle (χ) of the substrate strip (10, 10′; 11, 11′) around the measuring shaft (16, 17) by an adjusting drive.

Provided is an automatic material supply device for a secondary battery. The device includes a material supply reel configured to enable a wound material for the secondary battery to be loaded, a material pulling part configured to pick up an end of a newly wound material for the secondary battery loaded on the material supply reel, and configured to pull the material a predetermined distance, and a material transfer part configured to hold a side of the material pulled out by the material pulling part and configured to pull the fixed material to a material connector. The automatic material supply device for the secondary battery is advantageous in that it is possible to automate a preparing process for replacement after loading a secondary battery material into a loading position.
