High-quality black-and-white photographs of large old machines and tools

Not only tremendous size and general facility, but note the floor. World's best industrial surface; wood bricks, they're set on end.
At lower left is what appears to be a drain, probably isn't. It's a cast iron floor plate, near certainty of mounting in front of portable boring mill, large radial drill, or functions as serious assembly table.

Seeing photo I referred to wasn't specified by post number, *440, is a clean floor etc as described; not shaper and vicinity in post *442.
What an error! It never happened before..........but plenty of times since then, lol.

Even in black and white that looks red hot...

Even in black and white that looks red hot...

Clearly . . .

It does indeed look to be glowing hot. I like how it follows the first rollers, then less and less until it is flat on the last rollers

The rollers look like they maybe glass.

Post *452, pic of near molten glass sheet.
Examining pic again, wondering if they are actually 'rollers' at all. There isn't an apparent pillow block or saddle bearing.
Might they be just forms that glass moves smoothly over? Seems with travel a bit acute to axis of those forms, would impart something like skiving, to reduce the corrugations.
Not sure a perpendicular feed would do that.

so what the one above that apparently comes down...are they making corrugated glass sheets???

[Toolmaker51]

That would be SOME product Corrugated glass! Haul that into the local window guy "yes, I'd like this little bathroom window re-glazed with THIS" right before whipping it out of the box......
Anyway, I think the wrinkles appear as it slides/ rolls out, almost like making home made pasta, has to be cradled and laid out to dry. Factory wise, the methods are completely automated.
I'm far behind in google quests; satisfying those (+ me) who want to know.

JUST THINK OF THE SEALER TO SEAL IT TO A FRAME!!!!! possiably snazzy roof pannels or some decreative stuff.
