Abstract
Abstract A method of traversing a strand between two spaced rows of strand-restraining elements moving together in the same direction to form a web is carried out by a strand-engaging member that orbits each row to alternately traverse the strand toward one and then the other row while forming a loop in the strand during each traverse and positioning the loop around at least one strand-restraining element. Rotary means traveling in the same instantaneous direction as the loop release it from the strand-engaging member.
