METHOD OF MEASUREMENT OF TENSION OF FLEXIBLE LONG-CUT MEMBERS AND DEVICE FOR REALIZATION OF THIS METHOD Russian patent published in 2004 - IPC

FIELD: measurement technology; measurement of tension of moving wire in the course of drawing.

SUBSTANCE: proposed method includes forming the supports for section of wire at two extreme points, tension of middle point of section by transversal force, measurement of resulting sag and analytic determination of the unknown of tension at tension limited by preset permissible error of measurement. Magnitudes of permissible sag and permissible error are related by definite relationship. Device proposed for realization of this method includes bearing rollers fitted on axles and pusher whose one end is engageable with article through force-sensing roller and other end is engageable with pressure unit and roller motion indicator. Novelty of invention consists in connection of pusher with body through hydraulic shock absorber.

EFFECT: enhanced accuracy and reliability of measurements.
