An arrangement for applying elastic, preferably thread elastic, to a travelling web (1) of material in a direction that is generally perpendicular to the feed direction (20) of said web (1), said arrangement (10) comprising means (2) for feeding the web (1) forwards; means (8) for storing and/or feeding elastic (5a-b) to the web (1); applicator means (9) for applying elastic (5a-b) continuously to the web (1), wherewith the applicator means (9) is moveable generally perpendicular to the web (1) and includes a thread guide (6) which is moveable between two outer positions, e.g. through the medium of a pivotal arm (7), said thread guide (6) being adapted to apply elastic (5a-b) to said web (1), and wherein the arrangement includes at least one thread stop (16). The arrangement is characterised in that the thread guide (6) is constructed to deliver the elastic (5a-b) to said stop (16) as it passes said stop (16) while moving to its outer position; and in that the thread guide (6) again picks up the elastic (5a-b) as it returns, wherewith the elastic (5a-b) passes through both the thread guide (6) and the stop (6) solely when passing by. The invention also relates to a method. <IMAGE> |
