It's a Texas rainmaking machine.

Shut it off! Shut it off!

Well, it used to be a Heidelberg Cylinder.

Still is a Heidelberg Cylinder press, an SBG to be exact.

But the shiny stuff is my contribution which is a foil stamping attachment for it. I took the idea for its design from my head to the drawing board, off to the machine shop, then assembled it as a one off machine in a little under 6 months.

How do you control the dwell on a reciprocating press?
I thought you could only do that with a platen action.

Correct, there is no dwell control on it. Can't stop and start a Heidelberg in mid stroke grinning

For just foil stamping the foil transfer is great with a cylinder press as it literally irons the foil onto the sheet at roughly 1/16" at a time which all but eliminates the gassing effect that can sometimes present real problems when doing larger foiled solid areas.

The use of dwell is really more for embossing/deembossing as more time in the impression mode can be of benefit to getting a crisper finished image while for foil stamping all that's occuring is the transfer of the foil to the substrate and dwell really isn't all that helpful.

Though a converted cylinder press capable of doing foil stamping can do embossing since it has heat applied to the bed area the finest work in embossing is usually done on a platen style press.
