In order to monitor/adjust production especially in a circular knitting machine comprising several knitting systems and several yarn feeder devices, yarn is fed to active knitting systems from several supply devices operating according to at least two different yarn feeder principles, in a non-positive manner. The individually fed amounts of yarn are continuously measured by means of scanned real rotation signals of the feeder devices. In order to obtain monitoring information and/or adjustment measures, comparisons are made with corresponding set amounts of yarn within at least one range of tolerance, the extent of which is adapted at least to yarn quality and/or yarn path parameters. At least one user interface can be configured in a display in a computerised production monitoring/adjustment device, whereby it is possible to select therein each individual yarn feeder device according to an optimum yarn transport principle for a specific knitting system, from a plurality of yarn feeder devices which are arranged on the circular knitting machine in an operative state for non-positive delivery of said yarn according to two different yarn transport principles, and to operationally allocate each individual yarn feeder device to said specific knitting system.

To provide a take-up device which joins a plurality of yarns of different types having different colors or the like with respectively desired lengths while successively selecting these in accordance with a preliminarily designed pattern, and exerts superior functions from the viewpoint of availability factor when the yarn is wound into a package. With respect to a single take-up package P placed in a take-up unit 15, a yarn-joining take-up device for different types of yarns is provided with a yarn-supplying unit 11 having supply yarns of a plurality of types, a yarn-joining unit 13 placed between the yarn-supplying unit and the take-up unit and a yarn-type selection unit 12 placed between the yarn-supplying unit and the yarn-joining unit, a yarn-joining device 19 is installed in the yarn-joining unit, and a yarn-type selection device 18 that selects the succeeding yarn on the yarn-supplying side to be joined to the leading yarn on the take-up package side is installed in the yarn-type selection unit; thus, the leading yarn, which is being connected to the yarn-type selection device, is guided to the yarn-joining device by the yarn-joining device and the yarn-type selection device, and the succeeding yarn is guided to the yarn-joining device by a succeeding-yarn guiding means to be yarn-joined therein.

In einer Anordnung aus Fadenverarbeitungselementen (2) einer Kettenwirk- oder Strickmaschine und einem Träger (1) sind die Fadenverarbeitungselemente (2) in gleichen Abständen in einer Ebene liegend aus einer Stirnseite (5) des Trägers (1) herausgeführt und mit einem Endabschnitt (7) in dem Träger (1) durch eine stoffschlüssige Verbindung gehalten. Zur Vereinfachung der Herstellung der Anordnung ist der Träger (1) in der Stirnseite (5) mit einer Nut (6) versehen, in der die Endabschnitte (7) der Fadenverarbeitungselemente (2) in einer sie mit dem Träger (1) stoffschlüssig verbindenden, aushärtbaren Füllmasse (3) eingebettet sind.
摘要:
A device for guiding a yarn which is supplied to a needle of a filling knitting machine to a hook or a predetermined position on the back of the needle. A yarn guide is capable of guiding a yarn such that horizontal reciprocation of a yarn guide member of the guide is not large, and when the yarn lowering edge at the end of the yarn guide member contacts and lowers the yarn, the yarn lowering edge does not slide on the yarn and does not give the yarn a high resistance. A means for supporting a yarn holding member, which has a yarn lowering edge at the free end thereof, in such a manner that the yarn holding member can be slid freely toward toothed openings of a pair of needle beds provided with their head portions opposed to each other and with the toothed openings positioned in the center, and moving down the yarn lowering edge during or after a sliding movement of the yarn holding member is provided in parallel with needles and sinkers provided on the needle beds.

To blow a yarn toward the needles and release it from the gripping device upon yarn feeding in a circular knitting machine, in particular a double cylinder one, a device is provided which is synchronized with each yarn feeding finger regardless of the number of feeds. The device comprises a control cam (31) provided with a boss (32) and rotated synchronically with the needle cylinder(s), an actuating cam (23) provided with two oppositely located notches (24) and connected to the control cam (31) through a normally disengaged coupling controlled by the machine program, and an actuating lever (18) which follows the profile of the actuating cam (23) and controls a valve (11) to cause it to engage with the control cam (31) and be operated by the boss (32) thereof to deliver pressurized airto the yarn feeding area. The valve (11) can be moved into the operative position by means of each yarn feeding finger associated with one feed.

Upstream-side and downstream-side V-groove guide rollers (24, 25) having substantially V-shaped grooves (241, 251) are rotatably supported in a feeding path in which yarns are formed into a folded yarn by a yarn combining device and is supplied to a yarn carrier. Shafts (242, 252) of the V-groove guide rollers (24, 25) are inclined relative to a direction perpendicular to the feeding path so that the folded yarn is twisted while being rolled from one inclined surfaces (243A, 253A) of the inclined surfaces (243A, 243B, 253A, 253B) of the grooves (241, 251) to valleys. Further, lines (X, Y) tracing the valleys of the grooves (241, 251) of the V-groove guide rollers (24, 25) in a circumferential direction forms one cycle of a sine curve for one turn of the V-groove guide rollers (24, 25) in an expanded state.
