Abstract
A system for curing a green tire made from elastomeric material includes a tire mold with a surface defining a cavity for shaping the tire. A plurality of vent passages communicate the cavity with the exterior of the tire mold. An inflatable bladder presses the tire against the surface defining the cavity for a predetermined time in response to fluid pressurization. A fluid pressure source pressurizes the bladder. A conduit communicates the fluid pressure source with the bladder. A restrictor member is located in the conduit for restricting the rate of increase of fluid pressure in the bladder to a predetermined rate of increase during the first one-third of the predetermined time. During the first one-third of the predetermined cure time, portions of the tire adjacent the plurality of vent passages cure and restrict the flow of other uncured portions of elastomeric material into the vent passages.
