Abstract (en)
The appts. to apply a lubricant to a running yarn has a supply container (1) for the preparation divided into compartments (2.1,2.2) for the components (3.1,3.2) of the lubricant. The feed system (5) has a number of inlet channels (9.1,9.2) at the entry side, with separate links to the container compartments (2.1,2.2), for their part-flows to be combined at the outlet side of the feed system (5). At least one dosing unit is in front of the feed system (5), to give a dosed vol. of at least one part-flow. A separate dosing unit (7.1,7.2) is pref. at each flow link (8.1,8.2) between the supply container (1) and the feed system (5), controlled independently of each other. The dosing units can be pumps. The feed system (5) has a mixing chamber (10), where the part-flows are combined. The mixing chamber (10) has one or more mixers (11) to blend the components (3.1,3.2) of the yarn lubricant together. The mixer can be a dynamic mixer. The applicator (14) has a yarn guide (15) with a track (16) forming the yarn channel (16) where a drilling (17) through the guide carries the main lubricant flow to the yarn (18). The applicator (14) can also have a jet to spray the lubricant at the yarn (18). The applicator (14) can also have a rotating roller partially immersed in a container filled with the main lubricant flow, to transfer it to the running yarn (18). An Independent claim is included for the treatment of a running yarn with a lubricant where the lubricant components are held separately in the supply container, to be fed as separate part-flows to be combined into a main application flow. Preferred Features: The part-flows are brought into the main flow by independently dosed vols., where at least one dosed part-flow can be set to give the proportions for the component parts of the main mixed flow. The main flow is composed of the sum of the separate part-flows, to be delivered to the applicator. The components of the yarn lubricant are blended together in the mixing chamber. A further Independent claim is included for a dosing pump with its inlet connected to the mixing chamber, where the part-flows are combined. Preferred Features: The mixers in the mixing chamber are at least partially mounted to a rotating shaft which has a common drive with the impeller which forms the mixing shaft where it enters into the chamber, and is fitted with a motor at the other end. The impeller and the mixing shaft can be separate, interconnected by a reduction gearing. The impeller is composed of one or more pairs of cogwheels, with one or more pump outlets for each pair. The paired cogwheels are driven by a common drive shaft, and the dosed vol. flows are equal for each pair of cogwheels.

Es ist eine Präparationsvorrichtung, ein Verfahren zum Auftragen eines aus mehreren Teilkomponenten bestehenden Präparationsmittels auf einen laufenden Faden und eine Präparationspumpe beschrieben. Hierbei werden die Teilkomponenten des Präparationsmittels in mehreren Behältern getrennt voneinander bevorratet. Die Teilkomponenten werden unmittelbar vor Auftragung auf den Faden in Teilströme in eine Mischkammer geführt und zu einem Hauptstrom zusammengeführt und als vermengtes Präparationsmittel zu einer Benetzungseinrichtung geführt, die das in dem Hauptstrom emulgierte Präparationsmittel auf dem Faden aufbringt. <IMAGE>
