A fabric folding machine contains: a body and a limiter. The body includes an external housing, an internal housing, and a connection portion. The external housing has a first peripheral fence, a second peripheral fence, and two third peripheral fences, wherein the internal housing is disposed in the external housing, and between the external housing and the internal housing is defined a through hole which has a first segment and a second segment, a height of the first segment is more than that of the second segment, and a width of the internal housing gradually decreases from the first segment to the second segment. The first peripheral fence has a first orifice defined, and the second peripheral fence has a second orifice and two guiding apertures. The limiter includes a sheet and a protrusion, and the sheet has two openings defined thereon.

A folding apparatus for a continuous web being fed in a plant for the production of hygienic absorbent articles and intended to be folded into a “V” or “U” shape in a first and in a second longitudinal portion according to a longitudinal folding line parallel to a feeding line of the continuous web comprises a folding section including a first and a second power-driven, movable suction belt and an adjusting system for adjusting a relative position of the longitudinal edges of the continuous web once it has been folded; the adjusting system is configured to adjust the position of the first belt and/or of the second belt depending on at least a first information sent by the first sensor to the computerised control unit.

A folding apparatus for a continuous web for production of absorbent hygiene articles and intended to be folded into a “V” or “U” shape in first and second longitudinal portions along a folding line parallel to a feeding line. A folding section includes a contact unit extending along the feeding line and defining the folding line. First and second guides are positioned on opposite sides of the contact unit and respectively have first and second sliding surfaces. The first and second sliding surfaces extend in a helical fashion along the feeding line, each having a respective infeed section, where the web is not folded, and a respective outfeed section, positioned downstream of the respective infeed section according to a web feeding direction, where the web is folded in two and has the first portion and the second portion set at an angle to each other.

A web has a series of cut outs that define bridging portions therebetween. A method for folding the web includes providing the web to a first conveyor, folding the web about a folding wheel to define a folded edge that extends through the series of cut outs, transferring the web to a second conveyor having an included angle of 15 to 40 degrees in relation to the first conveyor, folding the web about a folding bar to maintain the folded edge, and spanning at least one cut out with the folding bar and contemporaneously contacting at least two bridge portions with the folding bar to maintain the folded edge of the web about the folding bar as the web passes the folding wheel edge.
