Device and method for assembling material panels

The invention relates to a 1. Device (1) for assembling material panels (10)， in particular for dividing a web product (2) extending along three spatial directions (X， Y， Z) and having finite dimensions in at least two spatial directions (Y， Z)， the device ( 1) comprises at least one cutting device (5) having a cutting tool (3) and a base (4) and a guide device (6)， wherein at least the base (4) of the cutting device (5) is movably arranged along the guide device (6)， the device (1) having a first drive (7) for moving the cutting tool (3) relative to the base (4) and a second Has drive (8) for moving the base (4) relative to the guide device (6). The operator of a material panel production plant， in particular for wood material panels， is to be offered a possibility， particularly in operation， for the assembly of material panels. In particular， the energy costs to be incurred for the assembly of material panels from a web material moving at a high production speed are to be reduced. For this purpose， it is proposed that at least one drive (7， 8) be provided for changing between motor and generator operation. The invention also relates to a method for assembling material panels (10).
