Abstract (en)
[origin: EP1486597A2] A shedding control method, of a loom, for vertically moving each of heald frames (18) through a crank mechanism (24, 26) which has an eccentric portion (48) to be rotated in one direction by a heald frame driving electric motor (38) provided in each heald frame, comprising steps of rotating at a first rotational speed the eccentric portion in a first section between an intermediate rotational position of the eccentric portion corresponding to when the heald frame is located at an intermediate position between an upper limit position and a lower limit position and between a top dead center rotational position of the eccentric portion corresponding to when the heald frame is located at the upper limit position; and rotating at a second rotational speed different from the first rotational speed the eccentric portion in a second section between a bottom dead center rotational position of the eccentric portion corresponding to when the heald frame is located at the lower limit position and the intermediate rotational position; and wherein the relation in magnitude of the first rotational speed and the second rotational speed is made to correspond to the relation in dimension of the first section and the second section. <IMAGE>
