Raymark Friction had a Fiberglass/Rayon blend opening/blending/carding/layout/resin-coating/curing line for making laminate sheets running off of a line shaft from sometime in the 1920's until they shutdown in 1997: if it works (and is made safe), don't change it!They are in good shape. There is a note in Vol 1 that makes a reference to a third volume, I'll have a look next time I'm in town.
Edit - A quick search brings in dates of 1957, I can't believe they would use lineshaft illustrations in a book that "new". And there was a third volume published.
