The invention relates to a method for producing a device for storing solids, liquids and/or gases, especially a container (1) for storing food. According to said method, a strip (10) is deformed in a spiral shape, whereby a lateral surface (2) of the device is formed. The longitudinal edges (24, 26) of the strip (10) are bent along a bending line so as to form an edge and the adjacent longitudinal edges (24, 26) are interconnected. The inventive method is characterised in that a recess (16) is made in the strip (10) along the bending line before it is bent to form the edge. The invention also relates to a device for carrying out this method, comprising a bending station followed by a connecting station (46). The device is characterised in that a recess (16) can be made in the strip (10) at the bending station (38), along the bending line, using a machining tool (12, 14) that is located in front of the bending tool (42a, 42b) for forming the edge. |
