ABSTRACT:
An arrangement for a transverse spreading of a travelling web, in particular a paper web or the like, which web is in contact with at least one spreading appliance adjustable by its curvature. Said curvature is pretrimmable in the web travel direction and said appliance comprises a body member, and supported hereat, a spreading member mainly corresponding to the entire transverse extension of the web. The spreading member comprises a support member adapted to be bent towards the web, and at least two mainly rigid, web contacting rolls, which are located one after another in the web transverse direction and are journalled at said support member. Said arrangement comprises means for the provision of a movable support of said spreading member and a deflectable adaption of said support member for an adjustment of a second curvature of the spreading appliance, in a direction towards the web and independently from the pretrimmed curvature, said adjustment being carried out by adjustment members so, that a separation between the body member and the support member is altered at a plurality of different positions in the transverse direction of the web.
