Control arrangement for weaving loom or the like

摘要

A circuit receives a signal indicative of each loop of weft yarn being drawn off a cylindrical storage member and computes based on this data the time required for a given number of loops to be drawn off. The calculation includes an allowance for the time required for mechanical components associated with the releasing of the weft yarn from the storage device to actually reach a weft yarn release position and the time required for the calculation per se to be performed.
