Abstract: A vulcanizing mold for winter and all-season vehicle tires includes a mold body and an inner side mold surface having a negative tread profile having negative profile elements for molding a positive tread profile having positive profile elements of the vehicle tire to be vulcanized. Lamellar plates are arranged in the negative profile elements and configured to generate sipes in the positive profile elements. The negative profile elements include a shoulder negative profile element and at least one venting slot arranged within the shoulder negative profile element. The venting slot runs parallel and in spaced relationship to one of the lamellar plates arranged in the shoulder negative profile element. At least one cylindrical vent is arranged only axially outwards with reference to the venting slot.

Abstract: An apparatus and method are provided for the helical winding of an essentially band or strip-shaped reinforcing element onto at least one ply of a pneumatic tire blank. The apparatus includes a rotating tire or belt build-up drum, a winding wheel disposed upstream of the drum and connected with devices for applying tension to the reinforcing element, and sensors that detect the position of the reinforcing element on the winding wheel, and the tension applied to the reinforcing element, and convey these values to a control device. The winding wheel is connected with a motor for driving or slowing the winding wheel, whereby at least two tensioning and guide rollers are radially spaced relative to the winding wheel such that the reinforcing element, which is guided over the winding wheel, forms a defined looping angle.
