    Abstract: This invention describes a process for orienting and drawing multiple-layer thermoplastic materials, in particular of a tubular type, wherein a) the tubular exiting from the heating tunnel is brought up to the orienting temperature of a first material having the highest orienting temperature, while the material of the remaining layers is still in a plastic state; b) said first material is subjected to a first partial drawing process, while the remaining layers plastically deform to follow its expansion; c) the temperature of the tubular is dropped to the orienting temperature of a second layer; d) this second layer is drawn, while at the same time continuing to draw the previous layer; e) the phases c) and d) are repeated for the subsequent layers, until the maximum allowable degree of drawing is achieved for each layer.

    Abstract: A novel air cooling ring is provided herein for supplying successive streams of cooling air to a surface of a tubular bubble of plastic, after its extrusion from an annular die surface, the annular die surface having a die axis. The air cooling ring includes a ring-shaped plenum chamber which is provided radially-outwardly of the die axis from annular die orifice. The ring shaped plenum chamber has an air inlet, and an air outlet. The ring-shaped plenum chamber also includes an upper lip, which includes such air inlet and the air outlet, and a lower deflector lip. A forming cone extends radially outwardly from the air cooling ring. An annular air passage, which is formed in the forming core, communicates with the air outlet in the ring-shaped plenum chamber. A plurality of axial outlet ports is provided in that annular air passage. An annular air chamber communicates with the plurality of axial outlet ports to direct cooling air downwardly and radially-outwardly to a lower annular air outlet, and then to divert the cooling air both in an upward direction between a surface of the forming cone and the tubular bubble of plastic and radially-and-horizontally-inwardly between the lower portion of the upper lip of the ring and the deflector lip.

    Abstract: A process for forming a rod of bioabsorbable polymeric material includes extruding the material at a temperature above its melting point at a controlled rate of between 0.4 to 20 feet per minute to form a continuous rod. The continuous rod is then cooled by passing the rod through a cooling bath to cause nucleation. The continuous rod is passed through a first puller running at least at the same speed as the extruder. A second puller is provided which is moving faster than the first puller so that the continuous rod is elongated at a ratio of between 2 and 12 times. During this elongation, the rod is heated to a temperature of between 55null C. and 140null C. in an oven located between the first and second pullers. The rod is annealed at a temperature of between 70null C. and 110null C. after being elongated but prior to exiting the second puller. Upon exiting the second puller, the tension in the rod is released and the continuous rod is then allowed to cool. A cutting station is then provided to cut the continuous rod into desired lengths.

    Abstract: Methods and devices are provided to actively apply finish to one or more yarns in motion at speeds greater than about 3000 m/min, to achieve a finish application of 0.2 wt. % or more, and with a coefficient of variation of finish concentration of 10% or less. The devices are compact, portable and readily installed at a variety of positions on a fiber processing line. The devices of the invention contain the finish so that contamination of the surrounding areas is prevented. The devices may be used to provide an overfinish to a moving yarn between heated godet rolls. The so-provided heating may be used to dry the yarn and to promote curing reactions in the finish and between the yarn and finish compounds. The invention also includes the finished yarn products so produced. A yarn with increased finish uniformity is provided with an overfinish actively applied and dried on the draw bench before the first winding operation. The yarn products of the invention may be used in textile and leisure fiber applications, and in industrial fiber applications, such as in tires.

    Abstract: A system for producing cables includes an extrusion apparatus with one or a plurality of extruders and a head through which the line or lines for the cable pass and after which an induction heating apparatus is arranged, whereby downstream of the head and the induction heating apparatus is a suspended vulcanization tube that extends horizontally in the manner of a catenary curve and that constitutes a plurality of tube pieces of which the tube piece adjacent to the head is a telescoping tube enabling access to the head. It is the object to increase the efficiency of a cable production system using measures that make possible earlier and more rapid heating of the insulating layers applied in the head and simpler operation of the system and concurrently permit simpler and more rapid access to the molding die when cleaning the head and when a tool is being exchanged. The induction heating apparatus downstream of the head is securely installed in the movable tube of the telescoping tube or is securely attached to the movable tube, and together with this tube is movable, whereby the movable tube of the telescoping tube along with the interiorly installed of exteriorly attached induction heating apparatus is insertable into the immobile tube of the telescoping tube or can slide over this tube.

    Abstract: An apparatus for producing a tube having a round cross-section over a major portion of its length and intermediate its ends having a flattened oval cross-section. The apparatus includes an extrusion head with an extrusion die through which the tube is extruded. A pinching device, which includes opposed pinching elements, is arranged at the extrusion head so as to be selectively moveable together to press on and pinch the tube to produce the oval cross-section of the tube. The rollers are selectively moveable apart to not pinch the tube to enable the tube to be extruded round, whereby a round tube with an intermediate flattened oval shaped portion is produced.
