摘要： The invention relates to a pneumatic vehicle tire, which has a tread (1), which has a tread segment (6) that is arranged radially outside, said tread segment having a material strip (7) that is arranged helically in windings approximately in the circumferential direction, wherein the material strip (7) in the region of the tread segment (6) has at least two layers (8, 9) in the longitudinal direction of the material strip, wherein the first layer (8) is formed of a first rubber mixture and the second layer (9) is formed of a second rubber mixture and wherein the layers (8, 9) connect the radially outer surface (10) to the radially inner surface (11) of the tread segment (6). The problem addressed by the invention is the creation of a pneumatic vehicle tire that has advantageous snow driving behavior and, at the same time, improved properties on a dry roadway. In addition, the tire should be simple to produce. This problem is solved in that the second rubber mixture has a Shore A hardness that is greater than the Shore A hardness of the first rubber mixture by at least 2 Shore A, preferably by 4 Shore A to 12 Shore A, and in that the first and the second rubber mixtures have approximately the same stress value. The invention further relates to a method for producing such a pneumatic vehicle tire.

摘要： The invention relates to a pneumatic vehicle tire, which comprises a tread (1), which has a tread segment (6) that is arranged radially outside, said tread segment having a material strip (7) that is arranged helically in windings approximately in the circumferential direction, wherein the material strip (7) in the region of the tread segment (6) has at least two layers (8, 9) in the longitudinal direction of the material strip, wherein the first layer (8) is formed of a first rubber mixture, and the second layer (9) is formed of a second rubber mixture, and wherein the layers (8, 9) connect the radially outer surface (10) to the radially inner surface (11) of the tread segment (6). The problem addressed by the invention is that of achieving a pneumatic vehicle tire that has lower noise emissions during driving operation and more even wear and is improved with regard to at least one goal conflict. In addition, the tire should be simple to produce. This problem is solved in that the first and the second rubber mixtures have approximately the same Shore A hardness and in that the first and the second rubber mixtures differ in at least one further physical property. The invention further relates to a method for producing such a pneumatic vehicle tire.

摘要： The invention relates to a device (4) for guiding and pressing band-shaped or strip-shaped profiled rubber to a construction body (2) which can be rotationally driven in order to construct a tyre on a construction body. Said device comprises a forming device (6) in order to profile the rubber which is guided by the forming device and an endless strip (5) which is arranged downstream from the forming device in the direction of transportation of the profiled rubber, and rotationally guided in rotation about a first deviation body (31), in particular, rotationally symmetrical, rotationally mounted about a rotational axis (37) and about a second deviation body, in particular, rotationally symmetrical, rotationally mounted about a rotational axis (38) in order to transport the profiled rubber from the direction of the first deviation body into the direction of the second deviation body in order to deposit said rubber on the rotary driven construction body, in the deviation area of the second deviation body, whereby the orientation of the rotational axis of the second deviation body can be modified in a controlled manner in relation to the rotational axis of the first deviation body.
