APPARATUS FOR AREA MEASUREMENT OF ELONGATED STRIPS

摘要

APPARATUS FOR AREA MEASUREMENT OF ELONGATED STRIPS Apparatus for area measurement of elongated strips of different widths is described, which strips may be film to be treated, the strips to be measured being delivered manually or driven between rolls carried on parallel shafts, the number of rolls on one shaft which are actuated being determined by the width of the strips, the actuation rolls having magnets carried therein to activate switches to generate pulses for counting by a counter to give an area indication. The actuation rolls are preferably counterbalanced to reduce undesired movement.
