ABSTRACT:
To provide for positive guidance of shuttles in a multi-system traveling shed weaving loom, in which the shuttles move continuous, endless loop path, having a straight portion (15a) and two essentially semi-circular curved return path portions (15b), the curved return path portions are defined by a pair of guide strips or rails (32, 42) spaced from each other by a sufficient distance to accomodate the shuttles therebetween as they travel in the curved path, the inner guide strip (32) being formed of non-magnetic material. The shuttles carry permanent magnets (36) and travelers (16) carry, on a leaf spring (30), drive elements (25) having permanent magnets (26) interacting with the magnets (36) on the shuttles, the drive elements being pressed against the inner surface of the non-magnetic guide strip in the curved portion (15b) of the path and against a guide reed leaf (10) in the straight portion of the path. Tapered transition strips (33) connect the guide reed leaf and the curved inner strip to provide for smooth transition between the guide reed and the thinner inner guide strip (32).
