Abstract (en)

[origin: EP1580308A2] A start control method for a start control apparatus of a loom which executes a starting method selected from a plurality of starting methods including a normal start and a blank beating start in which a reverse rotation is performed by a predetermined amount so that a weft yarn which is already woven in is released from warp, beat-up motion without weft insertion is performed by the same amount as the amount of the reverse rotation while activating the loom, and then weft insertion is started, wherein the reverse rotation is not performed when the weft yarn positioned at a cloth fell has elasticity. It is determined whether or not the weft yarn to be exposed at the cloth fell has elasticity on the basis of information regarding the weft selection or information regarding the elasticity of weft. When a drive operation signal is generated, if the weft yarn is determined to have elasticity the normal start is executed.
