  • Patent number: 8057620
    Abstract: Multilayer absorbent pads for nappy/diaper pants are manufactured on a unit (1) comprising a first device (3a) and a second device (3b) by which respective first and second layers (4a, 4b) of absorbent material (5) are taken up from two infeed stations, shaped, and transferred to two release stations. The devices (3a, 3b) are synchronized in operation, and associated by way of a transfer station (8) at which the first layer (4a) of absorbent material is joined directly to the second layer (4b), positioned selectively and with the second layer still retained by suction on the second device (3b); the two layers are thereupon compressed simultaneously to form an absorbent pad (2) that emerges from the unit as a stable, one-piece core.

  • Patent number: 7399266
    Abstract: A method and machine for folding and finishing training pant diapers, whereby the diapers are formed from respective flat blanks, each of which is fed to a continuously-rotating, suction-type first wheel, and is folded into a U by clamping an intermediate portion of the blank on the first wheel by means of a folding member; retaining a trailing half of the blank on the first wheel, while detaching a leading half from the first wheel by means of a continuously-rotating, suction-type second wheel; transferring the leading half to a continuously-rotating, suction-type third wheel; and gradually superimposing the leading half of the blank onto the trailing half, as the trailing half advances on the first wheel, and after first removing the folding member from the blank.
