A machining apparatus and method are disclosed, with two blanking devices arranged on a feed path of material for blanking portions of material forming electrode tabs distributed in a step, by varying the period of the working cycles of the two blanking devices independently of one another at each blanking to increase progressively the step between the electrode tabs; the machined material is intended to be wound around a core to produce an electrical energy storage device; the increase in the step between the electrode tabs means that the electrode tabs are aligned on one another in the wound product, taking account of the fact that the dimensions of the product increase during winding.

An opening station for facilitating box opening may include a scanning station, an edge opening station, and a conveyor assembly. The scanning station is configured to measure a length L, height H, and/or width W of a substantially square box having a top, a bottom, two sides, and two edge portions. The edge opening station is configured to perform perforation operations on at least one of the two edge portions. A complete box opening system may include the scanning station, edge opening station, conveyor, and at least one of a top opening station and a side opening station.

A method for realizing articles having a predetermined area and aesthetic appearance uses frames to each of which a portion of material having a prevalent flat extension can be removably hooked. The method includes stitching or punching operations and cutting operations implemented on each portion of material in a first station, a second station and a third station sequentially. Cutting operations are executed on a first portion of material hooked to a first frame in a third station, while stitching or punching operations are carried out on a second portion of material hooked to a second frame and punching or stitching operations are performed on a third portion hooked to a third frame situated in the first station in phased relation.

A method of manufacturing a composite part comprises placing a composite material part comprising fibers and a thermoplastic resin on a matrix; moving a presser towards the matrix in order to thermo-stamp the part; and making at least one orifice in the part by moving at least one punch through the part and at least one compactor pushing back the material of the part moved by the punch and forming a shoulder around the orifice or one of the orifices. This method also comprises a step of placing a metal insert on the shoulder of the or at least one of the orifices.
