Abstract: A device for folding a web for producing absorbent sanitary articles along at least one longitudinal fold line parallel to its feed direction includes two diverting elements positioned on opposite sides of the web one after the other, to operate in succession on respective lateral portions of the web and allow transversal folding of one lateral portion on the other and both on the web. Each diverting element has a diverting surface which is used for folding and which is equipped with a plurality of holes to emit jets of air under pressure at a tangent to the diverting surface, directed transversely to the feed direction of the web along the same direction as the direction along which the two lateral portions are transversely folded by the diverting surface and defining between the latter and the web a laminar fluid bed.

Abstract: A method for making sanitary articles, includes: feeding along a longitudinal direction of movement a first web of material defining a main body of the article; feeding a pair of longitudinal strips; dividing each strip into a succession of trapezoidal pieces adjacent each other and each having a long base and a short base so the pieces of each strip can be divided alternately into first pieces having a first orientation and second pieces having a second orientation opposite to the first orientation; spacing the pieces of each strip from each other; rotating the first or second pieces of each strip by 180° in plane to give the pieces of the first strip the first orientation and the pieces of the second strip the second orientation; applying each piece on a first face so the long base protrudes laterally from the edge of the first web.
