Indirect Printing of AGM

A method for indirectly applying absorbent gelling material granules onto a non-woven carrier layer, said method comprises the following steps:

• transfering absorbent gelling material granules from a bulk storage of absorbent gelling material granules into recesses that are present at a surface of a transfering device, said recesses forming a pattern of recesses at said surface of said transfering device;
• moving said transfer device from a loading position adjacent said bulk storage to a meeting position where said non-woven carrier layer is adjacent to said transfer device;
• retaining said absorbent gelling material granules inside said recesses during movement of said transfer device;
• applying a first glue onto said non-woven carrier layer upstream of said meeting position before absorbent gelling material granules are deposited onto said non-woven carrier layer;
• transfering said absorbent gelling material granules from said recesses onto said non-woven carrier layer at said meeting position thereby forming a pattern of absorbent gelling material granules on said non-woven carrier layer such that at least some of said absorbent gelling material granules contact said first glue;
• and
• applying a second glue onto said absorbent gelling material granules after said absorbent gelling material granules have been deposited onto said carrier layer.
