ABSTRACT:
The invention relates to apparatus for folding diapers (1) and like articles, in which apparatus the article is advanced to a folding station by a conveyor (2). The folding station includes a driven folding roll (4) which co-acts with a counter roll (9) in a manner to feed the article to at least one driven transport roll (11,12). The transport roll guides the forward end (10) of the article (1) onto the cylindrical surface of a folding roll (16,17) co-acting with the folding roll (4) and intended, in a first folding phase, to be driven in a first transport direction through a given distance up towards the upper part of the folding roll and, during a second folding phase, to be driven in the opposite direction (A) and move the forward part of the article down from the aforementioned upper part. The folding roll is provided with a folding finger arrangement (7) intended for pressing a central part of the article into the nip between the folding roll and the transport roll (12) located therebeneath during the second folding phase.
