Abstract: A device for cleaning the inner walls of vulcanizing molds that are divided into upper and lower partial molds by means of a blasting device/nozzle and a manipulating device, with the blasting device and the manipulating device being accommodated and encapsulated in an isolation hood that is provided with an adapter ring, and with the isolation hood being suspended on a movable boom and connectable to the outer circumference of a partial mold by means of the adapter ring.

Abstract: A tread design for a pneumatic tire of radial construction for high-speed vehicles is provided. The tire has a height-to-width ratio of .ltoreq.0.6 with a tread design that is tied to the direction of rotation. The tread design comprises profiled elements that are steeply oriented in the circumferential direction at an angle to the equatorial plane of the tire and are arranged in the shape of V's. The profiled elements extend from a central portion of the tread into shoulder regions of the tire, with the profiled elements being angled-off at a bend region in the shoulder regions in the direction of an axis of the tire. Respective continuous inclined grooves that proceed from the central portion to the shoulder regions are formed between the profiled elements. A circumferentially extending rib is disposed in the equatorial plane and forms two central, circumferentially extending grooves, one on each side of the rib, between this rib and starting portions of the profiled elements.

Abstract: A tread design for a pneumatic tire of radial construction for high-speed vehicles is provided. The tire has a tread design that comprises profiled elements that each comprise, starting from a centrally disposed circumferential groove, in succession, a first part that is disposed adjacent to the central groove and extends parallel to the equatorial planes of the tire, aa longer, elongated central portion that extends at an angle of 5.degree. to 30.degree. to the equatorial plane and ends in a bend region, and a fork-shaped end portion that is disposed in a shoulder region of the tire and extends at an angle of 60.degree. to 90.degree.

Abstract: A tread design for a pneumatic tire of radial construction for high-speed vehicles is provided. The tread design comprises profiled elements that are steeply oriented in the circumferential direction at an angle to the equatorial plane of the tire and are arranged in the shape of V's. The profiled elements extend in a continuous manner from a central portion of the tread into shoulder regions of the tire and are angled-off at a bend region in these shoulder regions. Respective continuous, inclined grooves that proceed from the central portion of the tread to the shoulder regions are formed between the profile elements. Respective fork-shaped elements are provided in the shoulder regions in the vicinity of ends of the profiled elements remote from the central portion of the tread, with each fork-shaped element being provided with at least one short groove that opens into the shoulder region away from the bend region thereof.
