The inventor proposes to roll the tire,and to put it in the mold while still hot, so that no reheatingwill be needed. He prefers for the tire a hard and lough steel. The invention Is thus described : Fig. i shows a sectionalview of a tire and a pair of box-rolls in elevation, such as maybe used for rolling the tire wiih the plain interior flanges, andalso in elevation a pair of edging rolls having bevelled collarss
