摘要:
Eine Spulvorrichtung für Fäden besteht aus einem U-förmigen Spulenhebel, der um eine ortsfeste Achse schwenkbar ist. An den vorderen Enden des Spulenhebels sind Zentrierteller (29) drehbar gelagert. Zwischen den Zentriertellern kann eine Spulenhülse eingespannt werden. Weiterhin ist an dem freien Ende eines jeden Armes des Spulenhebels eine Laufschiene (9) schwenkbar angebracht. Die Schwenkachse liegt konzentrisch zur Spulenachse. Die Laufschiene untergreift die Enden der Spulenhülse (18). In der Betriebsstellung sind die Laufschienen (9) in eine obere Stellung verschwenkt. Zum Zwecke des Spulenwechsels werden die Laufschienen nach unten verschwenkt, so daß sie ein geringes Gefälle haben. Zumindest eine der Laufschienen steht in Verbindung mit einer Einrichtung (31) zur Entspannung der Zentrierteller (29).

Die Erfindung betrifft eine Spulvorrichtung zum Aufspulen eines Seils (2) auf eine um eine Drehachse (50) drehbare Seiltrommel (3). Die Spulvorrichtung (40) umfasst eine Seilführung (5) zur Zuführung des Seils (2) zu der Seiltrommel (3). Die Seilführung (5) weist einen Schwenkarm (6) mit einer Längsachse (49) und ein Umlenkelement (7) auf. Der Schwenkarm (6) ist um eine Schwenkachse (48) schwenkbar. Das Umlenkelement (7) ist an dem Schwenkarm (6) angeordnet. Die Spulvorrichtung (1) ist so ausgelegt, dass das Seil (2) beim Aufspulen auf die Seiltrommel (3) den Schwenkarm (6) vor dem Umlenkelement (7) passiert. Die Seilführung (5) umfasst ein Begrenzungselement (8). Das Begrenzungselement (8) ist so angeordnet, dass eine Schwenkbewegung des Schwenkarms (6) um die Schwenkachse (48) auf einen Grenzwinkelbereich (Δ) begrenzt ist. Das Umlenkelement (7) ist um eine Kippachse (47) kippbar. Die Kippachse (47) erstreckt sich entlang der Längsachse (49) des Schwenkarms (6).

PROCESS FOR SPINNING OR TWISTING YARNS, MACHINE FOR SPINNING OR TWISTING YARNS AND METHOD TO TRANSFORM A MACHINE FOR SPINNING OR TWISTING YARNS. A feature of the invention should be a process of yarn spinning or twisting, in which a yarn runs between a yarn feeding means (1) towards a yarn picking means, the said yarn picking means being connected to driving means to rotate the yarn picking means at a predetermined speed, in which a stretch of balloon is generated in a point located between the feeding means (1) and the picking means by the presence of twisting means. The fact that the value of the rotation speed of the yarn twisting means is such that it generates a helical path with oscillating spiral diameters along the distance existing between the yarn feeding means (1) and the yarn picking means, so that the path of the yarn, by the operation of the twisting means, creates a body of revolution from a diameter generating a balloon that has at least a hyperboloid structure (E) forming at least two stretches of balloons (B) consecutive to each other. A second feature of the invention should be the yarn spinning or twisting machine that includes a yarn feeding means (1) to supply at least a yarn (3), a yarn picking means for the yarn handled (3), twisting means arranged between the yarn feeding means and the yarn picking means that generate diameter generating (DB) a stretch of balloon of the yarn (3) in an area generating a stretch of balloon (B) with a generating diameter (DB), driving means (4) connected to yarn feeding or picking, and does not include elements limiting the balloon and is characterized in that the distance (LB) existing between the guiding means and the area generating a stretch of balloon is at least two times the diameter generating the balloon (DB), so that at least two stretches of balloon (B) are generated between the guiding means (8) and the area generating a stretch of balloon. Last, another feature of the invention should be the method to transform a yarn spinning or twisting machine including a set in which the height of the stretch of balloon (LB) is increased so that, by operating the twisting means, a body of revolution is created from a diameter generating a balloon that has at least a hyperboloid structure (E) that forms at least two stretches of balloons (B) consecutive to each other.
摘要:
The present invention refers to a process for the production and for the winding of at least one polyester multi-filament yam which consists of at least 90 weight %, in relation to the total weight of the polyester multi-filament yarn, of polybutylene terephthalate (PBT) and/or polytrimethylene terephthalate (PTMT), preferably of PTMT, to provide at least one yam package with long-term stability during storage and which is insensitive against elevated temperatures during storage and transport wherein polyester comprises an infrared absorbing pigment and/or a catalyst having infrared absorbing properties and that the polyester multi-filament yam is heat-treated by the use of infrared radiation during winding to a yarn package. In addition the present invention relates to said polyester multi-filament yam obtainable by said process wherein its elongation at break is in the range of > 60 % to 145 % and its boil-off shrinkage is in the range of 0 to 10 %. The present invention also claims a device for the winding of one or more multi-filament yams (3) comprising a commercial winder and at least one infrared radiant heater (9) arranged in a defined distance from the winder shaft (4) thereby irradiating a yarn package (5) which is placed on said winder shaft (4).
