    Abstract: A control device (53) for a clutch assembly (11) of a dobby comprises a selecting finger (28) that is driven by an electromagnet (37). The selecting finger is rigidly connected to an armature (47) that has a curved armature section and a straight armature section. Together with an appropriately curved pole (45) of the magnetic circuit, the curved armature section forms an air gap (48) that is preferably not influenced by the pivot position of the selecting finger. The other pole (46) of the electromagnet (37) forms a preferably straight air gap (49), said air gap being variable and having a size that is a function of the pivot position of the selecting finger. Due to the existing lever ratios, the maximum width of the trapezoidal gap is substantially smaller than the path of the outer end of the selecting finger (28) between its two selection positions. The distance (A) between the pivot center (32) and the variable air gap (49) is substantially smaller than the length of the selecting finger (28).

    Abstract: A device for coupling and uncoupling heald shafts (1) to shaft rods (2) in a loom comprises first and second coupling portions (6, 7) attached to shafts (1) and shaft rods (2), respectively, and a latch member (8) for latching the coupling portions to each other. A pivotable actuating member (14) is pivotably coupled to the shaft drive to move the coupling portions between a rest position, where the shaft rods are uncoupled to the shafts, and a working position, where the shaft rods are coupled to the shafts for operation of the device. A support member (15) is coupled to the shaft drive and comprises a plurality of elongate holes (17) for receiving and guiding the shaft rods during operation of the loom and V-shaped notches (19) aligned with each of the elongate holes to secure the shaft rods in a stable position when the rods are uncoupled to the shafts. The shaft rods are designed so that the ratio of the length of each rod to the maximum stroke height, i.e.

  • Patent number: 5462093
    Abstract: A motion damping system for a weaving machine which includes a pair of elastic members connected to supply damping force in opposite directions to an oscillating member. The oscillating member is connected to a control member so as to oscillate to and from a median position. The oppositely directed elastic members apply continous force to urge the oscillating member toward the median position.

  • Patent number: 5370157
    Abstract: An arrangement for releasably fastening an elongate first member (1), such as a heald rod in a loom, within a second member (2), such as a coupling element between the heald rod and a shaft drive. The second member includes a first recess (4a) forming a cavity (4) and a second recess (4b) for receiving the first member. A fastener (3) is threadably coupled to the second member within a third recess (4c). The fastener engages the first member at a bearing point (5) within the cavity to fix the first and second members together. This engagement bends the first member within the cavity so that relative movement between the two members is reduced or eliminated.

  • Patent number: 5365983
    Abstract: A device comprises a member having a number of recesses open on one side, into which the shaft rods of a loom can be inserted and movably retained. The device also includes a mechanism which prevents an unintentional removal of the shaft rods. The positional relationship of the device with respect to the shaft drive in a loom ensures that the shaft rods not required perform a lifting movement during the operation of the loom.

  • Patent number: 5348054
    Abstract: A device for coupling two outer parts (3) to a third part (2) disposed therebetween. The device includes a plurality of fasteners 7 each threadably mounted to an opening (9) in one of the outer parts and a cylindrical recess (6a) in the third part. Each fastener 7 has a conical head 7a that rests against the opening in the outer part. The outer parts project over the cylindrical recess so that an annular cavity is formed between the head of the fastener and the third part. Thus, the head of the fastener elastically deforms the outer part into the annular cavity so that additional forces may be transmitted from the outer part to the third part. In addition, the inner surface of each outer part is parallel to the third part so that the third part may be replaced without any effective movement of the outer parts.

  • Patent number: 5348053
    Abstract: An apparatus and method for coupling and uncoupling a plurality of heald shafts (31) to and from their corresponding shaft rods (2) in a shaft drive. Male and female coupling parts (3, 5) are connected to each heald shaft and shaft rod, respectively, and a locking element 4 is pivotally mounted within the female coupling part to lock these parts together. Two drive units (7, 8) pivot two U-shaped shackles (9, 10) from an open position into a closed position. This movement unlocks each locking element so that each male coupling part and heald shaft can be vertically removed from its female coupling part. At the same time, the shackles secure each female coupling part so that they will remain in position to receive the next heald shaft.

  • Patent number: 5345973
    Abstract: An adjustable connection link is provided between the dobby and the first crank lever of the control rods of each loom heddle frame. The connection link consists of two tubular bars of hollow aluminum alloy section pieces, preferably of rectangular cross-section. There is at least one internal rib that is perpendicular to the major sides of the rectangle. The section pieces, moreover, are cut away along opposing sides at their adjacent ends in order to expose the corresponding parts of their internal ribs. These are kept pressed, one against the other, in an adjustable position by a bolt. The bolt is threaded into one end of the section piece and passes through a slotted hole in the corresponding end of the other section piece.

  • Patent number: 5273079
    Abstract: A weaving method makes use of a set of weaving frames arranged such that, in each weaving cycle, some of the weaving frames are held in an identical extreme position, while all remaining weaving frames are moved in order to provide different tensions for the top and bottom warp threads at the moment of beating up. The shed is formed so that at the moment of crossing, as the weaving frames change position, the length of the course followed by the crossing warp threads is equal or almost equal to the length of the course followed by the warp threads held in the extreme position.

  • Patent number: 5191917
    Abstract: A spreader tool for the individual coupling and decoupling of heald shafts to or from the respective drive rods or shaft pulls of a heald loom is constructed to be inserted into a gap between two connecting spring sections from above the loom healds for spreading the connecting spring sections apart. The tool has two jaws that are normally biased into their closed position by a spring for insertion into the gap and are then spread apart by a cam drive or the like. The assembly and disassembly is thus greatly facilitated and the time previously required for this type of work has been substantially reduced.

  • Patent number: 4817676
    Abstract: In a loom shedding motion device, the pivoting motion of cam follower levers driven by cams is transmitted by way of thrust rods, bent levers to the leaves of the loom. Extending from a central bearing of each lever are arms on the motion input side of the lever and the motion output side of the lever. The arms are cranked or offset relatively to a bearing lug of the bent lever so that pivot points or arrangements at the ends of the arms and a center bearing are disposed substantially on a straight line, so that, because of the transmission forces in the shedding motion, the pivot experience torques which are operative around the bearing center and whose resultant is disposed vectorially on the bearing axis. The bent levers are therefore supported on the spindle or bearing shaft without tilting, so that the operation is free from wear and little lubricant is needed.

  • Patent number: 4392515
    Abstract: The invention relates to a weaving loom with waving shed heddle frames which when built in accordance with the invention insures that the heddles do not have lateral displacement when the frames are operated by controls respectively acting on both sides of the frames so that the motions of the respective sides differ from each other in their pattern. The bars of the frames are pivotably connected to the supports of these frames. These supports slide in stationary guides which restrict the lateral motion of the frames.
