Device (1) and method for maintenance of a machine tool, wherein the device (1) comprises a fixed frame (7) comprising a support base (10) and a movable frame (12) comprising a flat alignment face (13) defining an alignment plane; an abrasion system (14) structured to be able to abrade an internal surface (4) of a seat (3) of the machine tool, wherein the movable frame (12) is rotationally fixed to the fixed frame (7) to be able to rotate with respect to the fixed frame (7) around a second rotation axis (100), wherein a main body (15) of the abrasion system (14) is angularly rigidly fixed to the movable frame (12) so that a first rotation axis (17) of an abrasion element (16) defines, with the alignment plane and in a reference plane (18) perpendicular to the alignment plane, a fixed acute angle (19) complementary to a nominal taper angle (5) of the internal surface (4) of the seat (3), wherein the second rotation axis (100) is parallel to the alignment plane and perpendicular to the reference plane (18), and wherein the method comprises rotating the movable frame (12) with respect to the fixed frame (7) around the second rotation axis (100) to position the alignment face (13) perpendicularly to a rotation axis (22) of the spindle (2) and activating the abrasion element (16) to abrade the internal surface (4) of the seat (3).

Method for producing an electric battery cell comprising: - stacking in an interleaved manner a plurality of first sheets (1) in a first electrically conductive material and a plurality of second sheets (2) in a second electrically conductive material, wherein each first sheet (1) comprises a first tab (5) and wherein said first tabs form a first stack (7) in which said first tabs are in mutual contact; - in a first station, mutually pre-welding the first tabs (5) to each other in the first stack (7) by means of a laser beam (10) to spatially fix the first tabs (5) to each other; - subsequently, moving the first (1) and second sheets (2) interleaved from said first station to a second station; and - in the second station, welding the first stack (7) of first tabs (5) to a first electrical contact (13) to realize an electrical connection between all the first sheets (1) and the first electrical contact (12).

A floor structure (1), and a relative method for controlling the temperature, comprising a floor layer (2), a supporting layer (10) realizing a continuous air chamber (11) having an aerial extension comparable to an aerial extension of a floor surface (3), and an air movement system (20) to generate an air flow through the floor layer (2) from the air chamber (11) to the floor surface (3) and/or viceversa, the air movement system (20) comprising one or more air mouths (23) opening into the air chamber (11) at a distance (D) from a side surface (14) of the air chamber (11).

Machine (1) and method for the recovery of glass material from a decommissioned photovoltaic panel (5) comprising at least a covering layer (6) made of glass material and a support layer (7) made of polymer material having a first face (71) adjacent to and in contact with said covering layer (6), wherein the machine (1) comprises a compression station (2), a heating station (3) and a bending station (4), and wherein the method comprises compressing the photovoltaic panel (5) to generate at least one fracture line in the cover layer (6), heating the photovoltaic panel (5) to bring the support layer (7) to a temperature higher than a softening temperature of the polymer material and subsequent bending the photovoltaic panel (5) to generate a first bending moment acting on at least one portion of the support layer (7) with the first face (71) of the support layer (7) in compression to separate the glass material of the cover layer (6) from the first face (71) of the support layer (7).
