Abstract
An apparatus and method for transferring and applying discrete lengths of material to a moving web is disclosed. The material is supplied to a plurality of applicator units (41). Each applicator unit (41) has a first applicator segment (42) and a second applicator segment (43). The applicator units (41) are rotated around a drum axis (35a). The web supply section (11) feeds the web (21) to a fluted corrugating roll (22). The first applicator segment (42) is rotated about a first axis and the second applicator segment (43) is rotated about a second axis, wherein the first and second applicator segments (42) and (43) are linearly aligned when passing under an extruder (27). Then the first and second applicator segments (42) and (43) rotate around the first and second axis to place the first and second applicator segments in space relationship when the material (33) is bonded to peaks (21a) of the web (21). Then the first and second applicator segments (42) and (43) rotate back around the first and second axis to place the first and second applicator segments back in linear alignment. The web removal section (15) removes the web (21) from the fluted corrugating roll (22) and pulls out the corrugations in the web (21), wherein the material (33) is stretched and bonded to the web (21) between the bonded peaks (21a).
