20080206381 | METHODS AND SYSTEMS FOR MANUFACTURING YARNS FOR SYNTHETIC TURF - Systems and methods for manufacturing synthetic yarns for synthetic turf. The systems and methods include rollers for advancing a plastic sheet forward through a manufacturing process. The plastic sheet is cooled and heated on opposing sides by alternating temperature rollers to pre-form the plastic sheet such that subsequent synthetic yarns made from the sheet will have a curled shape. The plastic sheet is then cut longitudinally by a plurality of slitting blades along the length of the sheet to form a plurality of single strand synthetic yarns. A drawing device then draws and stretches the single strand synthetic yarns to a desired width and thickness, wherein the drawing device includes a drawing oven for heating the yarns, and a plurality of drawing rollers for pulling and stretching the heated yarns. The final product drawn yarns comprise sealed, smooth yarns with desirable rounded edges and a curled tip. | 08-28-2008 |
20090004313 | APPARATUS FOR MAKING A SPUNBOND WEB - An apparatus for making a spunbond web has a deposition surface, a spinneret above the surface for producing filaments that move downward along a path toward the surface, and a cooling chamber below the spinneret. Cool process air is supplied to the chamber to cool the filaments as they pass downward through the chamber. A laterally closed stretching unit downstream of the cooling chamber has laterally closed side walls that have portions that diverges downward. A connecting region between the stretching unit and the cooling chamber substantially excludes access of air from outside to the filaments as they pass from the cooling chamber to the stretching unit so that the filaments drop from the stretching unit onto the deposition surface. | 01-01-2009 |
20090022833 | APPARATUS FOR MELT SPINNING AND WINDUP OF SYNTHETIC YARN - An apparatus for melt spinning and winding up synthetic yarns comprising a spinning appliance, a treating appliance and a windup machine. The treating appliance comprises a runoff godet for guiding the yarns before entry and distribution of the yarns into a plurality of winding stations in the windup machine, the runoff godet being arranged above the windup machine and guiding the yarns in a parallel side by side arrangement on its circumference. The runoff godet is arranged transversely to a winding spindle and above the windup machine, the windup machine comprising a plurality of head yarn guides which are disposed upstream of the winding stations and are arranged in a vertically oriented runup plane. To ensure a very low-friction guidance for the yarns, the invention provides that the head yarn guides of the winding stations are disposed downstream of the runoff godet immediately in the yarn path and such that on deflection of the yarns into the runup plane an angle of deflection of not more than 15° is not exceeded. | 01-22-2009 |
20090104299 | FILM STRETCHER - A film stretcher utilizes a spring bias to clamp the film. The film stretcher may include a stretch head having one or more clamps positioned about the film in locations necessary to clamp the film for stretching in one or more axes. The clamp may utilize a spring to provide the clamping force. The stretch head may include structures that operate to counter the spring bias to move the clamp to one state and then to allow the spring bias to move the clamp to another state. Thus, the stretch head may effectively clamp and unclamp the film. | 04-23-2009 |
