    摘要： Synthetic yarn to be bulked and heat set is supplied to a plurality of ovens in coiled form and is subjected to an even hot flow of dry gaseous fluid to bulk and heat set the yarn as it passes successively through the bulking oven and the heat setting oven. Safety controls are provided to prevent damage to the yarn when the conveying system is shut down and the yarn is being conveyed through the system.

    摘要： A glass fiber bulk strand roving that is made up of a multiplicity of strands, each of which is made up of a plurality of individual fibers, for example, 200 of such fibers. Each strand of the roving has a multiplicity of rather long, axially extending loops, for example, axially extending loops with a calculated length of at least 6 inches, and a multiplicity of shorter, unbroken, cross-axially extending loops that are formed in the axially extending loops of such strands. The axially extending loops and the cross-axially extending loops interengage and intertwine with one another to form a composite entangled structure. The roving of the present invention is made by a process that uses a finger wheel to form axially extending loops in strands and a spinner downstream of the finger wheel. The looped strands from the finger wheel pass through a relatively unrestricted passage in the spinner which imparts a twist to such a looped strands, and then through a relatively restricted outlet orifice that is downstream of the outlet of the spinner. A back-up or puddling of the looped strands occurs in the spinner near the outlet thereof, due to the axial length of the loops in the strands and the restriction in the outlet of the spinner in the form of the outlet orifice, and this back-up or puddling of the looped strands in the spinner, in conjunction with the spinning thereof, results in the formation of the cross-axial loops in the axial loops of the strands.

    摘要： An apparatus for recovering bulkiness of a nonwoven fabric by blowing hot air and heating the nonwoven fabric transferred in a transfer direction, includes a case member that has both end portions in the transfer direction opened; an entrance and an exit provided to openings on opposite end sides, in the transfer direction, of the case member to transfer the nonwoven fabric; and a blast opening provided on the entrance side of the case member for blasting hot air inside the case member toward the exit. Inside the case member, a sectional area at a first position downstream of the blast opening is wider than at a second position located between the blast opening and the first position. Hot air blasted from the blast opening flows downstream through the first and second positions while coming into contact with one of two faces of the nonwoven fabric inside the case member.
