A selvage forming apparatus (1) forms a leno selvage construction by using a first selvage yarn (16a, 16b) and a second selvage yarn (16c). The selvage forming apparatus (1) includes a selvage-yarn-path switching device (2) that moves a path of the first selvage yarn (16a, 16b) in a weaving-width direction and a selvage shedding device (3) that moves a path of the second selvage yarn (16c) in a top-bottom direction. The selvage-yarn-path switching device (2) includes a selvage-yarn guide member (5) having an eyelet (4) through which the first selvage yarn (16a, 16b) is inserted and a first drive device (8) that switches a position of the eyelet (4) between two positions that are on the left and right sides of the second selvage yarn (16c). The selvage shedding device (3) includes an engagement portion (9) that engages with the second selvage yarn (16c) and moves so as to move the path of the second selvage yarn (16c) in the top-bottom direction. The engagement portion (9) moves along a revolution path including positions at which the second selvage yarn (16c) is closer to the first drive device (8) than the eyelet (4) and farther from the first drive device (8) than a tip end of the selvage-yarn guide member (5) in the top-bottom direction at a position of the selvage-yarn guide member (5).

An angular servo-motor for the controlled positioning of elements connected to weft or warp yarns, in a weaving machine, essentially comprising a position control angular motor, with direct current sent to a "brushless" rotor (1), the latter connected to a sequence of elements consisting of cables (5) and small heddle-carrier looms (10, 11); the servo-motor in question is capable of conferring an alternating motion to the aforesaid small heddle-carrier looms (10, 11), such to obtain the desired weaves between the weft and warp yarns.

A selvage device (1) includes two supporters (20, 21) whose movements are restricted to a selvage-shedding direction and having thread guides (32) for guiding selvage threads (3), a driving motor (33) that is rotated in forward and reverse directions, and a motion-converting mechanism converting the rotation of the driving motor to reciprocating motions for the supporters. The motion-converting mechanism includes a first gear (35) attached to an output shaft (34) of the driving motor, a second gear (36) meshed with the first gear and having a first pivotal connecting section (53A) at a position distant from a center of rotation (36a) of the second gear in a radial direction thereof, a second pivotal connecting section (53B) which is provided in one of the first gear and a third gear (37) directly meshed or indirectly linked with the first gear and is positioned distant from a center of rotation (35a, 37a) of the first gear or the third gear in a radial direction thereof, and linking rods (51A, 51B) respectively provided for the two supporters, the linking rods having first ends respectively connected to the first pivotal connecting section and the second pivotal connecting section and second ends connected to the corresponding supporters.

A false selvedge forming device in looms is described, of the type comprising a drive shaft performing an alternating rotational movement and a pair of arrays of heddles, for moving warp yarns, connected by means of respective transmission means to said rive shaft for an opposing alternating movement, said transmission means being in the form of a pair of bundles of cords, on the one hand connected to the upper ends of said heddles and on the other hand converging towards two opposite points of a rotating member integral with said actuating shaft, the bottom ends of the heddles being retained by tensioning means.
