This article looks into problems which would accompany an attempt to increase the speed of looms equipped with a jacquard machine.
Each lingo vibrates violently with an increase in speed. The grade of its vibrations was judged by the distribution of points of the lingo's descents. As a way to judge that state, sparks were discharged from a lingo placed on special recording paper. A controlled plate for the harness was devised in order to narrow the range of distribution of points of the lingo's descent. A plate was also devised to control the vibrations of the harness. The defective parts resulting from a speed increase were improved, and the warp tension and the weight of the lingo were investigated. The results of these efforts suggest that the speed of a loom equipped with a jacquard machine, at present, 130rpm, can be increased to a maximum of 180rpm.
