| 摘要 |
An apparatus is described which is formed for expanding elongated, ribbon-shaped metal elements moving in the longitudinal direction and suitable for forming open section elements such as upright sections or plaster sections or closed section elements such as passages or pipes, the apparatus includes a feed station, a cutting station, a positioning station and a connection station, with the feed station being formed for the at least substantial continuous feed of at least one metal element to the cutting station. The cutting station is formed for producing at least one continuous meandering incision which extends in the longitudinal direction of the at least one metal element and by which at least two longitudinal portions of the at least one metal element having meandering longitudinal edges are produced. The positioning station includes at least one in particular rotating or circulating positioning device having a plurality of positioning elements, with the positioning elements being formed for engaging into openings formed in the at least one metal element and for positioning portions of the meandering longitudinal edges in defined positions with respect to one another. The connection station is formed for connecting the mutually positioned portions of the meandering longitudinal edges. A method is furthermore described for expanding corresponding metal elements. |
