Abstract: A pneumatic tire for vehicles has a belt and a reinforcing material layer embedded in at least one rubber mixture. The belt is made of a material that is selected from the group of steel, aramid, carbon fiber, natural fiber, magnesium, and magnesium compounds. The reinforcing material layer is a single-ply or multiple-ply layer that is oriented at an angle between 0 degrees and 5 degrees to the circumferential direction, and is made of at least one polyester thread and/or polyester cord.

Abstract: In a method for producing an air restrictor, use is made of at least one liquid or tacky substance to join perforated plates to one another and to seal the air restrictor. The substance can be, for example, an adhesive contained in capsules. The adhesive is liberated by bursting the capsules inserted between the perforated plates.

Abstract: A device for picking up a sheet trailing edge from an upstream cylinder and transferring the sheet trailing edge to a gripper system of a downstream drum, as viewed in sheet travel direction, includes a sucker guide mechanism having a movably mounted sucker carrier whereon sucker heads subjectible to an application of vacuum or suction air are disposed. The sucker carrier is constructed as a tubular part having a longitudinal axis and being movable perpendicularly to the longitudinal axis thereof. The tubular part is formed with a vacuum or suction air duct extending in the interior thereof and is formed of carbon fiber-reinforced plastic-material laminate.
