<p>An apparatus (20) and method for stretching a continuously moving elastomeric web (22) in a cross machine direction (122) includes a pair of rotatable, cylindrical rims (30,32) which are located adjacent the elastomeric web (22). A supporting mechanism (50) is connected to the cylindrical rims (30,32) to guide the rims (30,32) for rotation about their axes (34,36). The axes (34,36) of the cylindrical rims (30,32) are oriented to position the rims (30,32) at a close spacing (42) at a first location (44) and a far spacing (46) at a second location (48). The far spacing (46) is substantially greater than the close spacing (42) relative to the elastic web path (26). A gripping means (60) is located on the cylindrical rims (30,32) such that, as the rims (30,32) are rotated by a driving means (70), the gripping means (60) receives the elastomeric web (22) and holds the elastomeric web (22) as it is stretched in the cross machine direction (122). The driving means (70) is connected to the cylindrical rims (30,32). In addition, each cylindrical rim (30,32) may have a center opening therethrough defined by its inner circumferential surface (38). A facing sheet (102) may be supplied through the center opening and bonded to the stretched elastomeric web (22) to provide a laminated web which is stretchable in the cross machine direction (122). <IMAGE></p> |
