Abstract
The invention relates to a method and a device for guiding bands to be joined to one another along their longitudinal edges, comprising guide elements which form tracks for guiding the bands that are configured such that the bands approach one another in the transport direction and the longitudinal edges thereof rest on one another at a non-overlapping contact point. At least one of the tracks may be configured to undulate with a wavelength of ¼≦λ≦2, such that transverse displacement of the band guided thereon occurs. The axes of rotation and/or longitudinal central axes of the guide elements may also be inclined towards one another at different angles of inclination in relation to a horizontal plane of reference, such that the band guided on said track is rotated about its longitudinal axis in the transport direction.
