This is interesting!
Long ago I watched at the local retread shop as car tires were retreaded. The process was identical to this video, including the labor and no automation. Sole proprietor doing everything.
Then later I worked in a specialized factory where I handled uncured rubber like this, preparing it for making special order o-rings. I spent quite a few hours in front of a 'rubber mill', a device with steel rollers like an old laundry wringer, blending ingredients into the broad strips that then went to the molds.
