Abstract:
The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. During assembly of the elastomeric laminate, elastic material may be advanced and stretched in a machine direction and joined with either or both first and second substrates advancing in the machine direction. The apparatuses according to the present disclosure may be configured with a plurality of spools, wherein each spool comprises a single elastic strand wound onto a core. The elastic strands are unwound from respective spools by rotating the spools about the cores. Neighboring elastic strands may be spaced or separated from each other at a desired distance in a cross direction by advancing the elastic strands through a strand guide that may comprise a plurality of tines or reeds. The assembled elastomeric laminate may then be accumulated by being wound onto a roll or festooned in a container.
