PURPOSE: To properly rock a reed combined with an output shaft even at a high speed rotation by preparing a cam drive capable of selectively switching the output shaft into a specified stroke and an unspecified stroke. CONSTITUTION: In a shuttleless loom weaving a terry cloth and/or a smooth fabric, rollers 11, 12 of a lever having a roller are workably connected to the circumferential profile surface of eccentric rings 8, 9 transmitting the movement of an output shaft 45 arranged on the driving shaft 3 electrically driven and also a link mechanism consisting of a first and a second four-link levers 24, 25 is incorporated between the lever and the above described output shaft 45. Further, the internal tooth of the above described first and second four link levers 24, 25 is meshed with the external tooth of a mobile shaft so as to be switched alternately or zigzag by the switching device 54 of the controller 33 arranged on the above described driving shaft 3 via the mobile shaft shown by the Z part, and whereby a reed combined with the output shaft 45 forms a prescribed rocking angle. |
