A method for producing a breathable web, comprising: feeding a web on the surface of an anvil roller rotatable about its axis and having a plurality of welding protrusions cooperating with a welding element, welding said web at a plurality of welding spots on head surfaces of said welding protrusions and forming respective annular welding seams at said welding spots, about respective welding projections, and respective thin membranes located within said annular welding seams and adjacent to the head surfaces of said welding protrusions, and removing said thin membranes after said welding by means of a peeling roller having an outer surface tangent to said head surfaces of said welding protrusions.

Method and apparatus for producing a breathable web and relative web

Apparatus for forming transversal welds on a composite web material, comprising at least two superimposed sheets of material, suitable for use in the production of sanitary articles, comprising: a feeding unit including first and second feeding means configured to advance the composite web along a main straight direction X at a speed V. an ultrasonic welding unitarranged between the first and second feeding means, comprising at least one ultrasound source coupled to a sonotrode having a flat welding surface and an anvil unit having at least one anvil element movable along a closed path, which has a straight portion parallel to the main direction X.

Device and method for forming ultrasonic welds on web materials in continuous movement

An elastic structure for absorbent sanitary products, comprising a sleeve comprising a first layer and a second layer overlapping each other, at least one elastic thread, and a plurality of first connecting portions spaced apart in a longitudinal direction, wherein each of said first connecting portions comprises two first welds arranged on opposite sides of the thread, wherein the first welds weld said first and second layers to each other in a first longitudinal portion of said sleeve, and a plurality of second connecting portions spaced apart in the longitudinal direction, wherein each of said second connecting portions comprises at least one second weld, wherein said second welds weld said first and second layers to each other in a second longitudinal portion of said sleeve without axially connecting the thread to said second longitudinal portion of the sleeve.

Elastic structure for absorbent sanitary products, and a method and apparatus for its production

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

Conveyor device for laser treatments

A device for cutting, using laser beams (B, B), 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 () for supporting said material (A) in a position corresponding to the area of cutting where the laser beam (B, B) 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 () and suction and/or air jets systems.

Devices for treating film material, for instance for manufacturing sanitary products

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 &#x3bc;m and 2000 &#x3bc;m. Preferentially, the laser spot has a wavelength of between 9.0 &#x3bc;m and 11.0 &#x3bc;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.
