Abstract
A stand-alone machine and a process for forming crosswise filaments for non-woven fabric comprises two sets of non-traversing edge spacing pins, each set with a gripper, and a traversing set of slider pins. The sets of pins are placed close together. Crosswise filament yarns are engaged by these sets of pins. The slider pins then traverse and pull the filaments to their full length. The crosswise filaments are cut and fixed to edge elements, which preferably may including adhering the crosswise filaments to selvage filaments. The edge elements are then separated to draw the crosswise filaments to their full width. The invention provides increased speed, precision, and flexibility in making crosswise filaments for non-woven fabrics.
