Forgive me, the uptake is driven with a hand crank. Speed is relatively slow and manually driven.
Let-off tension is provided by only a slight drag to the supply spool, which i assume to be negligible (only enough drag to prevent momentum of supply spool from dropping fabric faster than it...
Thanks Compositepro,
The the "telescoping" is happening on the takeup spool. I've included a diagram illustrating our rewind fixture. Between the supply and takeup spools are a single set of tensioner rolls. The tensioner rolls are geared together and are fitted with a slip clutch to...
Thanks MikeHalloran,
I think we'll look to incorporate another roller or two and perhaps mount one to be slightly adjustable for minor skew adjustments as you described. I am curious however regarding the rollers being slightly convex as you say. You do mean the center diameter is slightly...
I've built a setup for taking a mesh-like fabric from a large supply spool and wrapping it onto smaller spools. Currently the fabric travels from the supply spool, through two closely spaced reels which are fitted with a slip clutch to provide specific tension, then directly onto the smaller...
I'd like to create a 3D map model from public terrain elevation data (national elevation dataset [NED] or digital elevation model [DEM] data). The available data seems to be configured for other specialized (and expensive) software packages.
1. Has anyone ever done anything like this using...
