Speed control for weft feed spool in weaving looms.

摘要

A method to control the speed of the weft feed spool in weaving looms, characterized by the fact that it consists of feeding at least two items of detected data into a control mechanism, the use of these data by this latter to calculate, as a number of windings, the variation (R) of the reserve from the average reserve which itself is determined by the reserve sensor (B), and any appropriate adjustment which may be required of the speed of the feed spool.
