Life of the patent
3 dated eventsAbstract
a method for traversing a plurality of strands between two spaced rows of strand-restraining elements moving together in the same direction in substantially the same plane to form a web is implemented by a plurality of strand transfer members moving in a single closed path spanning the rows of strand-restraining elements so that the members pass between strand-restraining elements on one of the rows and above them on the other row. There is a means provided for moving each strand back and forth across the path into engagement with the strand transfer members and a means for disengaging each strand from each strand transfer member beyond the other row and depositing it as a loop around at least one of the strand-restraining elements.
