Abstract: A conveyor device (10) for conveying a material (M) through a treatment station (101) where the material (M) is subjected to a laser treatment (12) capable of leaving contamination residues on the conveyor (10). The conveyor (10) outlines a closed loop trajectory passing through, after removing the treated material (M), two brushing stations (103, 106) where the surface of the conveyor (10) is subjected to brushing with a washing station (104) interposed where the conveyor (10) is subjected to washing through the projection (1040, W) of washing liquid.

Abstract: A device for splicing the free end of a strip of web material to a homologous strip of web material being supplied includes a first moving element and a second moving element, each of which is able to function alternatively as retention structure for the free end and as guiding structure for the web. The moving elements are, at least in part, translatable with respect to one another for connecting the free end to the web, performing the operation of splicing. The first and the second moving elements are selectively orientable between a position of opening, in which the moving element has a gripping formation exposed to receive the free end, and a position of closing, in which the gripping formation faces the other moving element of the device to allow the free end to connect to the web.

Abstract: A device for cutting, using laser beams (B1, B2), a material (A) such as a material for manufacturing sanitary products comprises a supporting formation for the material (A), such as a motor-driven belt, including a net (72) for supporting said material (A) in a position corresponding to the area of cutting where the laser beam (B1, B2) acts. Typically said net is a wire net, e.g., made of steel, bronze or a combination of the two, to which there is preferentially associated a rotary cleaning brushes (9) and suction and/or air jets systems.

Abstract: A device for carrying out a “re-pitching” operation, i.e., an operation for changing the pitch between articles included in a flow of moving articles, includes one or more elements for conveying the articles, which are able to perform an orbital movement about a principal axis between a position for pick-up and a position for release of the articles. The speed of the orbital movement is selectively variable in the passage between the position for pick-up and the position for release. Members are provided for distribution of subatmospheric pressure to the conveying elements to enable them to carry out selectively an action of suction to pick up the articles. The members include a distributor, which can turn about the aforesaid principal axis. Set between the rotating distributor and each conveying element is a respective flexible pipe or hose for transferring the subatmospheric pressure to the conveying element.

Abstract: A device for subjecting to laser treatment articles, in particular articles chosen between sanitary products and components of said products, comprises a laser-beam source configured for applying to the articles a laser spot with a diameter of between 50 ?m and 2000 ?m. Preferentially, the laser spot has a wavelength of between 9.0 ?m and 11.0 ?m The control unit is configured to regulate jointly the power of the laser spot, the instantaneous relative speed of the laser spot with respect to the article treated, and the instantaneous diameter of the treatment laser spot.

Abstract: Described herein is a device for splicing the free end of a strip of web material to a homologous strip of web material being supplied. The device includes a first moving element and a second moving element, each of which is able to function alternatively as retention structure for the aforesaid free end and as guiding structure for the web of material being supplied. The moving elements are, at least in part, translatable with respect to one another for connecting the aforesaid free end to the web of material being supplied, performing the operation of splicing. The first moving element and the second moving element are selectively orientable between a position of opening, in which the moving element has a gripping formation, preferably of the negative-pressure type, exposed to receive the free end, and a position of closing, in which the gripping formation faces the other moving element of the device to allow the aforesaid free end to connect to the web being supplied.
