Abstract:
1. A method for indirectly applying absorbent gelling material granules onto a non-woven carrier layer, said method comprises the following steps: transferring absorbent gelling material granules from a hulk storage of absorbent gelling material granules into recesses that are present at a surface of a transferring device, said recesses forming a pattern of recesses at said surface of said transferring 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; transferring 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.
