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 laser cutting machine includes at least one galvo having a galvo field of view in which the galvo can cut a material moving with a speed past the galvo. A display in the machine provides an image of at least one pattern to be cut from a material, the pattern comprising of a plurality of objects with each object having a position on the material and each object comprising at least one cut. An optimizer in the machine receives the position on the material of each object of the pattern and assigns a start locations for each cut of each object and a trigger distance for each object to maximize the speed at which the material moves past the galvo while ensuring that each object is cut by the galvo at the object's respective position on the material.

A sheet transport system comprising an endless carrier belt that has a predetermined stiffness and is arranged to carry the sheets towards an end of a conveyer path where the sheet is separated from the carrier belt by passing this belt around a separating member that has a predetermined curvature, wherein the carrier belt runs in parallel with an endless conveyer that has a larger stiffness than the carrier belt and, at the end of the conveyer path, has a smaller curvature than the separating member.

The present invention relates to a rewinding machine equipped with a support system for the reel and the ribbon-like product.

In particular, the invention relates to a rewinding machine (1) for a ribbon-like product (N), comprising: a fixed support structure which supports an unwinding unit (SV) and a rewinding unit (RB); an independent first carrier roller (2), movable along a direction parallel to a support surface of the rewinding machine (1); a second independent carrier roller (4), movable in the opposite direction with respect to the first carrier roller (2); a third roller (3), placed between the first (2) and second (4) carrier rollers and movable integrally with the first carrier roller (2); a set of driving rollers (110) placed along a path between the unwinding unit (SV) and the rewinding unit (RB); a web (10), forming at least one loop, made of a material with an air-permeable texture, said web (10) unwinding between the second carrier roller (4), the third roller (3), and the set of driving rollers (110); one or more suction boxes (6) placed under the web (10) to retain the ribbon-like product (N).
