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