Abstract
A fluid absorbent tape is formed from a fluid permeable strip which is folded to form overlapping portions enclosing an area filled with a band of a fluid absorbent particulate material lying on at least a part of a width of the upper surface of the strip. In one example, the strip is folded along one longitudinally extending fold line centrally between the side edges of the strip such that the side edges overlie on another and are bonded together by a bead of hot melt adhesive, a strip of EAA or other suitable method. In another arrangement, the side edges are folded together to form a butt joint which is bonded by an overlying or underlying strip of EAA or similar material. A second band of material can be provided in a second folded portion overlying the first to form an S-shape with both being maintained encapsulated by the bonding of the side edges of the strip.
