Abstract
Official abstract text for this publication.
Absorbent pads for personal sanitary items are made by a device that comprises a set of pick-up heads ( 2 ) moving along a feed path (P), a first application unit ( 5 ) and a second application unit ( 6 ) by which a respective first portion ( 4 a ) and second portion ( 4 b ) of an absorbent pad are placed on the pick-up head ( 2 ), and a motion-inducing mechanism, coupled to the pick-up head ( 2 ), which is designed to bring about a relative displacement between the first portion ( 4 a ) and the second portion ( 4 b ), so that when the second portion ( 4 b ) is placed over the first portion ( 4 a ), the one will be covered by the other only in part. A method of making absorbent pads using the device in question includes the steps of preparing a first portion ( 4 a ) and a second portion ( 4 b ) of an absorbent pad, then placing the second portion ( 4 b ) over the first portion ( 4 a ) in such a way that the first portion ( 4 a ) is covered only in part by the second portion ( 4 b ).
First claim
