  • Patent number: 4098444
    Abstract: A hydrojet for propelling textile yarn at high speeds to a collector includes a source of high pressure water issuing from an orifice to form a jet stream, which is aligned to contact yarn passing through a slotted engager guide located directly above a tube through which the yarn is propelled by the jet stream. The angle of the jet stream with respect to the axis of the tube is about 6.degree..

  • Patent number: 4030168
    Abstract: A method of traversing a strand between two spaced rows of strand-restraining elements moving together in the same direction in the same plane to form a web is implemented by a pair of strand-engaging members associated with each row of strand-restraining elements for slideably engaging the strand and moving it in alternate traverses toward one and then the other row while forming a loop in the strand during each traverse. The loop is brought into a plane parallel to the plane of the rows of strand-restraining elements and beyond the rows. Means are provided for disengaging the loop from the strand-engaging members and depositing the loop around the strand-restraining elements.

  • Patent number: 4016631
    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.
