  • Patent number: 9303362
    Abstract: A calendering roller used to manufacture textured nonwoven fabric including papermaking fibers is disclosed. The calendering roller includes a positive pattern that includes a basic element having a ring shape and a repetition of said basic element along multiple rows and columns substantially overall a peripheral surface of the calendaring roller. The ring defines an apex relatively to a center portion of the ring defining a cavity and a grinded surrounding zone. The ring includes at least one radial channel putting in communication the cavity and the grinded surrounding zone so as to define a discontinuous calendering surface. The repetition is regular except for multiple substantially longitudinally and transversally oriented regions. The regions are of limited size with respect to a calendering roller size and randomly distributed so as to define multiple random longitudinal and transverse lines in the textured nonwoven fabric including papermaking fibers, generating a cloth-like visual texture.

  • Patent number: 9192268
    Abstract: A dispenser for paper, in particular absorbent paper, having a case in which at least two rolls of a paper web are housed. The case includes a base unit having at least a first housing and a second housing for holding respectively at least first and second rolls, and at least a first door and a second door installed on the base unit. The doors are designed, in the closed position, to respectively protect the first and second rolls and, in the open position, to provide access respectively to the first and second housings in order to reload them individually with rolls. The first and second doors have respectively a first and a second nozzle for dispensing the webs from the first and second rolls.

  • Patent number: 7988085
    Abstract: A system for dispensing a strip of absorbent product in the form of a roll, of the type comprising a roll, formed of a wound strip of absorbent product, axially delimited by a first lateral side and a second lateral side, a dispenser for dispensing the absorbent product in the form of a roll, of the type comprising a frame and a cover which is mounted such that it can move, means for holding and guiding the rotation of the roll with respect to the frame, which means comprise a first holding element for holding the roll and which is borne by the frame, and a second guiding and positioning element which is borne by the cover such that it is fixed in terms of rotation and which can be housed axially in a lateral housing of the roll, characterized in that the second guiding and positioning element comprises at least one projecting portion on which an internal wall of the second housing is able to slide for guiding the rotation of the roll if the roll is a complementary roll, and which is able to dig into the stri
