Abstract: An apparatus (1) is proposed for cutting off and joining a sheet element (2) to a container (3, 3'), the apparatus (1) comprising an operating unit (4) comprising a cutting device (401) and a joining device (402), wherein the cutting device (401) comprises a cutting edge (403) which surrounds the joining device (402). The operating unit (4) and the container (3, 3') are movable with respect to one another along a movement axis (Z) between a spaced condition, in which a sheet material (5) is interposed therebetween and is spaced therefrom, and a joined condition, in which the joining device (402) is configured to join the sheet material (5) to the container (3; 3'). The apparatus (1) additionally comprises a retaining device (6), configured to retain the sheet material (5) during the joining and the cut. In the joined condition, the cutting device (401) is configured to remain fixed relative to the joining device (402) and the retaining device (6) is configured to move along the axis (Z) from a tensioning position to a cutting position, the sheet element (2) being cut on the cutting edge (403) from the sheet material (5) during the movement of the retaining device (6) from the tensioning position to the cutting position. In addition to the apparatus (1), a relative method for cutting off and joining a sheet element (2) to a container (3, 3') is also provided.
