A method and an apparatus in which continuous strips (16, 18) of a first material, e.g., elastic strips, are continuously supplied to flexible strip supports (32) in a supply zone (S) while the strip supports (32) are in a linear configuration. The strip support (32) are carried on respective transfer members (30) which are mounted on a rotatable support (34) so that individual transfer members (30) follow a closed (orbital) path upon rotation of the support (34). The continuous strips (16, 18) are cut into discrete strips adhered to respective flexible strip supports (32) whose configuration, and that of the discrete strips (16, 18) adhered thereto, is then changed to a desired curvilinear configuration. The transfer members (30) are then brought into transfer contact in a transfer zone (T) with a moving web (24a) of second material, which may comprise the backing sheet of a disposable diaper construction, and the curvilinear strips (16, 18) are transferred to the web (24a). Alternatively, or in addition, the individual transfer members (30) are supported on radially translatable supports (48) so that during rotation the orbital radius and thereby the linear velocity of individual transfer members (30) may be selectively varied between a first radius and consequent linear velocity in the supply zone (S) and a second radius and consequent linear velocity in the transfer zone (T). The individual transfer members (30) may also be pivoted to selectively orient the strips (16, 18) relative to the moving web (24a) in the transfer zone (T). |
