摘要:
The device (1) is used to cut a longitudinally moving thread-shaped body (9). It comprises a cutting blade (5) and an anvil (6) interacting with the cutting blade (5). A solenoid actuator for the cutting blade (5) comprises a plunger coil (3), a two-piece magnet return path yoke (21, 22), and a solenoid plunger (4) connected to the cutting blade (5). A supporting structure (7) carries the plunger coil (3) and the two half-yokes (21, 22). The half-yokes (21, 22) are attached by elastically deflectable arms (81, 82) by means of engaging closures (71-74) on the supporting structure (7). The device (1) therefore has a simple design and is easy and cost-effective to produce.

The present invention relates to a winding station for winding textile yarn onto empty tubes, comprising: - a winding mechanism (1 ) comprising two flanges (2) for gripping the ends of said tube (8), each flange mounted on a pivoted winding arm (6) , which arms position the empty tube in contact with a driving roller (14) , such that the longitudinal axis of the empty tube is above the longitudinal axis of the driving roller (14) , - a stationary, linear magazine (4) with a filling end (5) and a feeding end (7) , wherein - the filling end (5) and the feeding end of the magazine (4) are below the level of the flanges (2) , and - the filling end is above feeding end such that magazine (4) is inclined at angle, alpha, of less than or equal to 45 deg, - a lifting mechanism (11 ) comprising a pivoted arm terminating in a tube carrier (10) , which tube carrier (10) is configured to bring an empty tube from the feeding end of the magazine (4) to a space between the flanges (2) by an arc movement of the arm (9) . It further relates to and a winding assembly.

The invention relates to a device (1) for severing a thread that comprises two blades (2, 3). An electric drive (4) enables said blades to be moved counter to the action of leaf springs (6, 7; 9, 10) and into a ready position, from which the blades can be moved back by means of the force of the leaf springs in order to execute a severing process.

Spooling apparatus comprising means for rotatably mounting a first reel and a second reel, catching means for guiding a thread (1) to be spooled onto the first reel and further to the second reel and cutting means (5) for cutting the thread to be spooled when the thread to be spooled is guided from the first reel onto the second reel. The cutting means (5) comprises at least one cutting blade (7) which is moved at least in the cutting direction (K) as a result of the tension of the thread (1) to be cut.
摘要:
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Führen und Schneiden eines kontinuierlich zulaufenden Fadens bei einem Spulenwechsel in einer Aufwickeleinrichtung. Hierbei wird der Faden mittels eines beweglichen Fadenführers im wesentlichen parallel zur Hülse geführt. Dem Fadenführer ist eine Absaugeinrichtung nachgeordnet, die aus einem pneumatischen Absauganschluß und einer Schneideinrichtung besteht. Die Absaugeinrichtung wirkt mit einer Übergabeeinrichtung zusammen, um den Faden beim Spulenwechsel zu schneiden und das lose Fadenende des zulaufenden Fadens aufzunehmen. Um beim Spulenwechsel, beim Fangen und beim Anwickeln an einer durch eine Treibwalze angetriebene Hülse eine schonende Garnbearbeitung zu ermöglichen, ist der Fadenführer im Fadenlauf vor der angetriebenen Hülse und die Absaugeinrichtung hinter der angetriebenen Hülse angeordnet.
摘要:
Spooling apparatus and method utilizing reels (R) having generally radial slots (R5) in the end flanges (R2, R3) and a spiral track (32) forming an accessible long end (E1). The filament (F) is guided to a selected reel (R) by a reciprocating traverse sheave (11i). The traverse sheave (11i) moves to one axial end of the full reel (R) to arrange the filament (F) in a winding reference plane adjacent to the inside surface of the flange (R2). A transfer sheave (34a, 34b) moves between the two reels (R) to deflect the filament (F) approximate the empty reel (R) to position a portion of the filament in a direction substantially tangent with the periphery of the empty reel (R). A throw pin (42g) momentarily deflects the filament (F) from the winding reference plane to a cutting reference plane on the other side of the flange (R2). A snagger (41) snags the deflected filament and cuts the filament on a stationary cutter (38).

Cutter for cutting yarn in oscillating motion in textile machines, characterised in that it comprises a first upper mobile cutting element (16), a second lower fixed cutting element (18) co-operating with said first cutting element (16) in the cutting of yarn, a stem (20) for supporting said first mobile cutting element (16) and means (34) for driving the stem (20) acting to drive the movement of said first mobile cutting element (16) upwards, away from said second fixed cutting element (18) and downwards, towards and against said second fixed cutting element (18) in order to cut the yarn, with said stem (20) for supporting and driving said mobile part (16) which in the raised position defines a part for interception of the yarn in oscillating motion.
摘要:
A method and apparatus for cutting a thread, comprising a cutter (30) having a pair of blades (31A, 31B) which define a generally V-shaped blade edge (33) having end portions and a valley portion (33a) remote from said end portions, the cutter (30 being disposed at a predetermined angle (θ 2 ) so that said valley portion (33a) of said V-shaped blade edge (33) is positioned in the downstream side of a thread feeding path (P 1 ) than said end portions of said V-shaped blade edge (33), feeding means for feeding said thread (21) along said thread feeding path (P 1 ) that is disposed between said pair of blades (31A, 31 B), and guiding means (25) for guiding said thread (21) to said valley portion (33a) of said V-shaped blade edge (33) by bringing said thread (21) and said cutter (30) into close relationship. The thread (21) guided to said valley portion (33a) of said V-shaped blade edge (33) is cut with a tension of the thread in the downstream side of the cutter.
