【Abstract】 The filling insertion length determinations of two weft accumulators, IWF8407 and ROJ Elf, are analyzed, and the disadvantages and advantages of the two accumulators are compared. In the case without changing the drum diameter of weft accumulator, three determination methods to raise the filling insertion length accuracy are put forward--to increase electromagnetic needles, to add weft detector on the right side of waste edge warp and to measure the filling insertion speed.更多还原
