I'll bet that guy slept good at night!
"I've pulled over 5000 miles off and there is still lots of mileage left. Somebody else do this quality test--I'm tired!"
It's a dirty job but somebody's got to do it.
Back in the 50s and 60s, the family used to visit my grandparents in Akron, Ohio. It always smelled like rubber. If you left your car out overnight, it would be covered in black soot by the next morning. My grandfather and two uncles retired from Goodyear.
So, does anyone now exactly what the guy is doing?
Well my guess is he is adding layers of rubber to vulcanize to the existing compounds. We used to do a similar procedure when I worked in a retread shop in Pennsylvania in the late 60's early 70's. The rubber we had came in coils in a box and had an adhesive on the back that was exposed by removing the plastic wrapper and placed over the tire casing and then heated in a tire tread form under pressure to melt the compounds together and emboss the tread design into the tire.
The caption under the photo in American Machinist July 29, 1909 reads "Hand-Made Tire. Stretching the Fabric." They also show some Machine made tire processes, stretching and rolling the fabric. Those photos are not near as interesting as the one above.
P.S. Goodyear Tire and Rubber Company.
Sure wish Goodyear still made Model T tires...here in the US.
Goodyear makes the All Weather tread tires in the 4.50x21 size, where made ?? good question. Clinchers ???
