摘要:
Bei dem erfindungsgemäßen Greifer (11) ist ein Hohlniet (46) vorgesehen, der zusammen mit einem Klemmbacken (19) eine Führungstasche für den anderen Klemmbacken (21) bildet. Die Führungstasche ist zwischen zwei Axiallagerflächen (36, 49) festgelegt. Ein Abstandshalter legt dabei den Abstand zwischen den beiden Axiallagerflächen (36, 49) fest. Er weist dazu eine Anlagefläche (39) auf. Dieser liegt vorzugsweise eine konische Fläche (51) gegenüber. Nach dem Zusammenfügen der beiden Klemmbacken (19, 21) und dem Einsetzen des Hohlniets (46) wird dessen Schaft vorzugsweise so umgeformt, dass dieser an der konischen Fläche (51) anliegt. Bei dieser Anordnung ergibt sich das zur leichtgängigen Bewegung des Greifers (11) erforderliche Spiel aus dem Unterschied zwischen dem Abstand der Auflagefläche 39 des Abstandshalters 38 und der Axialfläche 36 des ersten Klemmbackens und der Höhe des Abschnitts (35) des zweiten Klemmbackens, der in der Führungstasche gelagert ist. Es besteht somit keine Gefahr, dass eine zu starke Umformung des Hohlniets zur Greiferschwergängigkeit führen würde.

Apparatus for loading a row of tuft retention sites (TRS) in a gripper loom with a row of tufts (T) arranged in a predetermined pattern sequence, the apparatus including a group of yarn sources movable along said row of tuft retention sites (TRS), drive means for sequentially moving said group of yarn sources along the guide means (33) and temporarily locating a desired yarn source in registry with a predetermined tuft site (TRS), and selectively operable tuft forming means which, on selection, transfer a tuft (T) from said desired yarn sources to said predetermined tuft site (TRS).

The invention relates to a method for driving one or several pile carriers (2) for the selection of one or several pile yarns (15), the pile carriers (2) moving between a first and a second extreme position for pile selection, each pile carrier (2) being directly driven through a drive motor (4), and activating the drive motor (4) for driving the pile carrier (2) occurring either according to the half reset principle, the pile carrier (2), each time being moved over an intermediate position, this intermediate position being a position between two extreme positions for pile selection, and the position of the pile carrier (2) being verified in this intermediate position, or occurring without half reset, one half reset movement being carried out in verification of the fact whether all pile carriers (2) are still in the positions verified, after a number of movements of the pile carrier (2) or after a certain time, said half reset movement being a movement of one or several pile carriers towards an intermediate position between two extreme positions for pile selection before moving to a next position for colour selection.

A carpet weaving loom comprises one or more tuft forming units (1), each of which is capable of supplying yarn tufts (26) of a number of different colours to a number of different weaving points sequentially. The or each of the tuft forming units (1) includes a demountable yarn carrier (2). In this way, when it is required to change the design of carpet being woven, or the creel (3) is exhausted, the or each yarn carrier (2) is simply replaced by another fed from a different creel (3). Preferably the creel (3) associated with the or each set of yarn carriers is itself removable from the remainder (6) of the loom and replaceable with the yarn carriers (2).

摘要:
This invention provides a method for weaving a pile fabric on a rapier Axminster weaving machine, whereby in the course of successive weft insertion cycles alternately one weft thread (1) alone and two weft threads (2), (3) one above the other are inserted between warp threads (4), (5), (6) so that a backing fabric (9) is woven, while pile threads (7) are so introduced that they are interlaced in the backing fabric (9) according to a three-shot weave by weft threads (1) inserted alone, which extend along the pile side of tension warp threads (6). According to this invention an Axminster pile fabric can be woven with pile formation according to a three-shot weave, while one pile row is formed per two weft insertion cycles. Also according to this invention an Axminster pile fabric is provided, in which in successive weft lines alternately one weft thread (1) alone and two weft threads (2), (3) one above the other are inwoven, and in which pile threads (7) are interlaced by weft threads (1) alone according to a three-shot weave.
