Abstract: A multilayer product made of paper-like material, includes at least one corrugated layer bonded to a first flat layer of canneté. A least one corrugated layer is constituted by a sheet of canneté which is shaped so as to form a wave. A method is also related for providing a multilayer product made of the paper-like material.

Abstract: An automatic machine for providing corrugated sheet-like elements includes elements for the continuous corrugation of a ribbon which moves in a longitudinal direction. The corrugation elements include an upper conveyor and a lower conveyor. The upper conveyor includes a plurality of upper abutment elements extended substantially transversely with respect to the longitudinal direction of motion of the ribbon. The lower conveyor includes a plurality of lower abutment elements extended substantially transversely with respect to the longitudinal direction of motion of the ribbon. The upper abutment elements are interleaved with the lower abutment elements in a work area. The upper abutment elements each include a bar adapted to make contact with the ribbon, while the lower abutment elements each include a vane, which has a substantially wedge-like transverse cross-section and is adapted to receive the ribbon in order to deform it.

Abstract: An automatic machine for providing corrugated sheet-like elements having a component for the continuous corrugation of a ribbon in motion in a longitudinal direction. The corrugation component includes an upper conveyor and a lower conveyor. The upper conveyor includes a plurality of upper abutment elements that are extended substantially transversely to the longitudinal direction of motion of the ribbon. The lower conveyor includes a plurality of lower abutment elements that are extended substantially transversely to the longitudinal direction of motion of the ribbon. The upper abutment elements are intercalated between the lower abutment elements in a work area. The upper abutment elements each comprise include a flap, which has, in the end adapted to make contact with the ribbon, at least one portion that has a grip component.

Abstract: An automatic machine for producing corrugated sheet elements, particularly for packaging, thermal insulation, soundproofing and the like, comprising elements for continuously corrugating a first ribbon that moves longitudinally, a feeder for feeding a second flat ribbon in step with the first ribbon, and a device for joining one another the first and second ribbons in discrete regions.
