Designed and built for a V belt manufacturer. Contains 2 sets of changeable nylon pulleys with grooves machined to mate with correct profile V belt. A rodless pneumatic cylinder raises and lowers the bottom pulley set for facilitating belt removal. Rollers are placed above each groove. These rollers "roll" over the V belt surface as the top pulley is rotated by an induction motor. Each roller has a proximity sensor placed above it. A V belt with an improper profile will not sit in its groove but be raised a bit thereby moving the roller towards the proximity sensor. A simple alarm system indicates to the operator which belt has an improper profile.
