Closing the cover of the mold. Entirely automatic, the "watch-case" mold is closed by pushing a button, which starts several operations. First the airbag is filled with live steam which circulates during the entire process; next an automatic timer sets itself for the proper length of time and temperature; next pressure is exerted to squeeze the tire into the mold pattern.
