摘要： A melt spinning apparatus for spinning a synthetic yarn, wherein the yarn is formed by combining a plurality of filaments and wound to a package by means of a takeup device downstream of the spinning apparatus. Downstream of the spinneret, an inlet cylinder with a gas-permeable wall and a cooling tube are arranged. The cooling tube connects to a suction device such that an air stream forms in the cooling tube in the direction of the advancing yarn. This air stream assists the advance of the filaments and leads to a delayed cooling. To ensure adequate cooling of the filaments within the cooling zone, an air supply device is provided for generating an additional cooling air stream which flows in the axial direction of the cooling tube for cooling the filaments downstream of the inlet to the cooling tube.

摘要： A method and an apparatus for melt spinning a multifilament yarn from a thermoplastic material, wherein a spinneret extrudes the thermoplastic material to strandlike filaments, which are initially in liquid form and then cooled to cause their solidification. For purposes of cooling, the filaments are precooled in a cooling zone downstream of the spinneret in such a manner that the filaments do not solidify. Subsequently, the filament bundle advances by the action of a coolant stream directed in the direction of the advancing yarn into a tension zone and undergoes further cooling until the filaments solidify in a solidification zone within the tension zone. To maintain the location of the solidification zone within the tension zone in a predetermined desired range thereof, an adjustable cooling of the filaments within the cooling zone is provided.

摘要： An apparatus and method for spinning a synthetic yarn, wherein a heated polymeric melt is extruded through a spinneret and the resulting filaments are combined and wound to a package by means of a take-up device located downstream of the spinneret. A cooling tube for the filaments is positioned below the spinneret, and an inlet cylinder which has a gas permeable wall is positioned between the inlet cylinder and the cooling tube. The cooling tube connects to an air stream generator in such a manner that an air stream develops in the cooling tube in the direction of the advancing yarn. The air stream is formed by a quantity of air that enters the cooling tube via the inlet cylinder, and the inlet cylinder is subdivided in the direction of the advancing yarn into several zones, each with a different gas permeability, for controlling the quantity of air entering the inlet cylinder. It is thereby possible to influence with advantage the precooling of the yarn and the formation of the air stream.

摘要： This invention relates to marking the yarn end of a package, which is wound at the end of a winding cycle over a narrow axial range of the package surface in the form of a yarn bead. For purposes of marking the yarn end (105) of the package (103), a marking strip (126) is used, over which the yarn (105) is wound. A winding mandrel (107) engages into the space between a yarn suction device (106) and the circumferential surface of the package, and is rotated oppositely to the direction of unwinding (112) of the package (103), thereby forming a yarn loop (110) with more than one winding. Inserted axially into the space between winding mandrel (107) and the circumferential surface of the package is the marking strip (126), over which the yarn is wound several times by reversing the rotation of the winding mandrel (107). The excessive yarn (105) of the yarn loop (110) is sucked into the yarn suction device (106), and subsequently the yarn end (105) is cut.
