APPARATUS FOR MEASURING LENGTH OF READILY DEFORMED ELONGATED MATERIALS Russian patent published in 2004 - IPC

FIELD: equipment for measuring length of readily deformed elongate materials.

SUBSTANCE: apparatus has material feeding and winding mechanism, length measuring device including optronic disk and rotation angle sensor, and system for measuring material displacement line bias, with said parts of apparatus being connected to microprocessor. Apparatus is further equipped with system for correcting resultant material length measurement values, said system taking into account material deformation value. Said correction system comprises optical amplifier, optoelectronic system adapted for identifying of stroboscopic effect and generating information and control signal at input of logic coincidence AND circuit, pulsed signal generator, and pulsed lamp connected with pulsed signal generator. Output of logic coincidence AND circuit is commutated through interface with microprocessor.

EFFECT: increased precision in measuring length of readily deformed elongate material by providing correction of fault resulted from material deformation.
