PCT No. PCT/CH85/00087 Sec. 371 Date Jan. 13, 1986 Sec. 102(e) Date Jan. 13, 1986 PCT Filed May 30, 1985 PCT Pub. No. WO86/00346 PCT Pub. Date Jan. 16, 1986.The apparatus comprises a slide (1) with a sley hook (5) reciprocally movable transversely to the slide path which after each step of the slide is automatically advanced into a reed space of the harness (4) disposed parallel to the slide path and is withdrawn after hooking in the warp thread. The step length of the slide (1) is exactly identical to the individual reed spacing which is optically sensed by a television camera (12) and is measured respectively calculated by an electronic equpment (16, 17, 18, 19). This continuous touchfree measurement of the reed spacing enables a faultless reading even on finest reeds, without the disadvantages of a mechanical sensing of the harness.
