摘要： The invention relates to a method and an apparatus for spinning and crimping a multifilament yarn, and wherein a thermoplastic melt is extruded through a spinneret to form a filament bundle. The filament bundle is divided into a plurality of bundle components before being crimped. Each bundle component is separately crimped and combined to a multifilament yarn after being crimped. The yarn is subsequently wound to a package.

摘要： A spinning apparatus for producing a plurality of yarns, wherein the yarns are produced by combining a plurality of filament bundles. To this end, the spinning apparatus includes a plurality of extruders for producing a plurality of melt flows, which are distributed by a plurality of distributor pumps to at least two spinning positions that are arranged side by side. Each of the spinning positions includes a plurality of spinnerets, which extrude a partial flow from a distributor pump to a filament bundle. Also, the spinning positions are arranged so that at least one filament bundle of one spinning position can be combined to a yarn with at least one filament bundle of an adjacent spinning position.

摘要： A vacuum pump (10) comprises at least one rotor shaft (12) having a rotor section (14) with a rotor (16), a bearing section (18) with a bearing (20), and a shaft sealing system (22) that is axially situated between the rotor section (14) and the bearing section (18). The shaft sealing system (22) axially comprises, on the side of the rotor, a gas seal (32) and, on the side of the bearing, an oil seal (34). The shaft sealing system (22) additionally comprises, between the gas seal (32) and the oil seal (34), a separating chamber, which surrounds the rotor shaft (12) and is ventilated by at least one separating chamber ventilation duct (60, 62). This enables the pressure difference that decreases via the gas seal and the pressure difference that decreases via the oil seal to be adjusted. An appropriate adjustment can prevent oil on the bearing side from passing through the oil seal toward the separating chamber.

摘要： A vacuum pump for producing a vacuum in a space which is to be evacuated comprises a housing (10) having a cylindrical inner space (22). An expeller (26) is arranged eccentrically in the inner space (22). A helical sealing element (34) is provided between the expeller (26) and an inner wall (38) of the housing (10) for forming at least one crescent-shaped conveying space. The housing (10) or the expeller (26) are connected to a drive device (44) for producing a relative rotary movement between the housing (10) and the expeller (26). The vacuum pump is configured as a dry-running vacuum pump.
