	I have worked with power transmission the past 30 years and ran across a customer wanting a "nestled pulley", something about the rim is formed in such a way as to not allow flipping of the belt. Has anyone else ever heard of this?

	I've heard of a 'jockey wheel' that just takes up the slack of the belt to keep the belt firm on the pulleys. The jockey wheel is mounted on a spring loaded arm. __________________ An EXPERT is a 'has been', that is a drip under pressure - My Boss

	Did this guy have any idea what he was talking about or did he just talk like he did? Could he be talking about a V belt? That would fit the description "the rim is formed in such a way as to not allow flipping of the belt"

	Was he perhaps speaking of a "nested pulley"? [What I am thinking of is a series of concentric pulleys that are of stacked side by side from greatest diameter to smaller diameters.] I believe we may have had a recent discussion on the topic. __________________ "Consensus Science got us into this mess, then why can't it get us out?" : Rephrase of Will Rogers Comment

	I think he meant a V belt pulley these do not allow the belt to flip __________________ "Multa ferunt anni venientes commoda secum, Multa recedente adimiunt". (The years as they come bring many agreeable things with them; As they go they take many away).

	Pulleys in a nest - maybe it refers to0 jockey pulleys. a jockey pulley manage the extension of the arc of contact. improves grip, (i don't know about flipping). Maybe it refers to an drive with an intermediate shaft on a 1/4 (or 1/2) twist drive. __________________ Never do today what you can put of until tomorrow - Student motto
