Measuring scissors-type arrangement has slide pieces moving along guide rail, with feet, carriage and track

摘要

The two drive side ends of the measuring scissors are connected to slide pieces running along a separate guide-rail and whose position on the rail is read by a linear scale. The angular position of the scissors in relation to the rail is plotted by means of a shaft encoder. The feet o f the scissors are fixed on the carriage of a guide track and are moved by telescopic drive mechanisms.
