  • Patent number: 7784499
    Abstract: A shaft connecting device (18) having a thrust rod (8) and a lateral support (4) that fit into each other with minimal transverse play. In addition, the shaft connecting device (18) has a clamping device (16) with a stop arrangement (60, 60?, 66) and a fixation arrangement (30, 30?), the latter connecting the lateral support (4) and the thrust rod (8) exclusively on their respective upper ends to each other. Any opening, closing and adjusting of the connections between the thrust rod (8) and the lateral support (4) is possible in a particularly simple and convenient manner. The lateral support (4) and the thrust rod (8) support each other, thus resulting in a high dynamic load-bearing capacity. The overall design is simple, clear and cost-effective.

  • Patent number: 7748291
    Abstract: The lever (11) is fitted with two rollers (20A, 20B) which are supported by a core (21) provided with a mounting bore (21B) on an articulated shaft, wherein the rollers (20A, 20B) are both mounted between two webs of a pair of webs which are added to the core (21). The webs (22A, 23B) are on the whole planar. A first web (22A) of each pair of webs is partially engaged in a hollow housing (21C) created on the lateral surface (21D) of the core (21). The second web (23B) of the same pair is maintained at a distance from the first web. The hollow housings (21C) are created on the two opposite lateral surfaces (21D) of the core (21) of the lever (11).

  • Patent number: 7637290
    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).

  • Patent number: 7506668
    Abstract: A device for modulating a first rotational motion of an input shaft (2) to a second, different from the first, rotational motion of an output shaft (3)in textile machines has a fixed complementary cam (1) provided with at least two cam profiles (1 a, 1b). At least one cam follower (5) is linked to the input and the output shafts (2, 3) and is provided with at least two contact rollers (6a, 6b), each following a different cam profile (1a, 1b), because of which the cam followers (5)are performing a rocking motion. The cam profiles (1a, 1b)arc internal cam profiles.

  • Patent number: 7493920
    Abstract: A shed forming device positions warp yarns in order to form a shed in accordance with a pattern to be woven, before inserting a weft through this shed. The positioning of the warp yarns is one potential cause of an increase or a decrease of potential energy in the shed forming device. One or several elements is added to compensate, by their change of state, partly or entirely for the decrease or increase of potential energy which is produced in the shed forming device by the positioning of the warp yarns. The change of state of the elements is effectuated without any coupling with the positioning of individual warn yarns. A weaving machine uses such a shed forming device.

  • Patent number: 4041986
    Abstract: An arrangement for forming sheds in a weaving machine having a plurality of operatively mounted heald shafts forming a heald shaft system. A drive shaft is rotatably mounted in the weaving machine and a plurality of eccentrics are non-rotatably mounted on the drive shaft one behind the other. A bearing is mounted on each eccentric; a rim member is mounted on each bearing and a sleeve is mounted on the rim member. One tie rod is pivotally connected to the rim member and another tie rod is threadably connected to the sleeve. The tie rods are connected via suitable linkages to the heald shaft. When the drive shaft rotates the heald shaft is reciprocated by the action of the eccentrics on the bearing and rim member.
