Abstract:
MAKING NON-WOVEN FABRICS WHICH LOOK LIKE WOVEN CLOTH BY STRIATING A WEB OF CRIMPED PARALLEL FILAMENTS, SETTING THE STRIATED WEB, AND CROSS-LAPPING THE STRIATED WEB.
Abstract:
A method for producing cross lapped structures such as battings from lightweight continuous filament webs utilizing high speed delivery means wherein the lightweight web is traversed across a moving collection means utilizing air currents to aid in the traversal, thereby producing a cross lapped structure.
Abstract:
Apparatus for the manufacture of cross-lapped structures is provided comprising means for continuously supplying a web, a support, means for traversing the web, the traversing means including an oscillating chute for receiving and discharging the web onto the support, the chute comprising opposed wide panels converging toward an exit, means for oscillating the chute, the chute exit being spaced from the support sufficiently for the web to billow outward, the chute having attached thereto baffle means to regulate and direct the currents of air generated by the oscillation of the chute.
