Arrangement and method for applying elastic element to a material web

An arrangement for applying elastic elements (1a, 1b, 1c) to a continuous material web (7) includes a first roll device (4, 5; 4, 5') for advancing the elastic elements (1a, 1b, 1c) in series and at a first predetermined speed (v1) and a second roll device (6; 11, 12) for advancing the material...

Zusammenfassung:	An arrangement for applying elastic elements (1a, 1b, 1c) to a continuous material web (7) includes a first roll device (4, 5; 4, 5') for advancing the elastic elements (1a, 1b, 1c) in series and at a first predetermined speed (v1) and a second roll device (6; 11, 12) for advancing the material web (7) at a second predetermined speed (v2). The second speed (v2) exceeds the first speed (v1) and the arrangement includes an abutment surface (6; 10a) arranged at a distance (d) from the first roll device (4, 5; 4, 5') which is less than the combined thickness of the elastic elements (1a, 1b, 1c) and the material web (7), an elongation of the elastic elements (1a, 1b, 1c) in their longitudinal direction being realized as they pass between the first roll device (4, 5; 4, 5') and the said abutment surface (6; 10a).
