Patent number: 8815032Abstract: A process for producing a tread for a tire with a radially inner layer composed of a first rubber material and with a radially outer second layer composed of a second rubber material and forming the ground-contact surface of the pneumatic tire. The first rubber material has higher electrical conductivity than the second rubber material, and where, in a form of a web axially dividing the second layer around the periphery of the tire, the first rubber material extends radially outwards through the second layer as far as the ground-contact surface. A ply of the first and second layers are constructed radially one on the other, on a rotationally symmetric construction surface, on one of the two axial sides of the web to be produced.Type: GrantFiled: October 27, 2008Date of Patent: August 26, 2014Assignee: Continental AktiengesellschaftInventor: Udo Frerichs

Patent number: 8251116Abstract: An apparatus for upturning a tire-building component on a tire-building drum has a roller lever. To provide an apparatus which is capable of upturning a tire-building component on a tire-building drum, and which achieves the upturn of the tire-building component without defects, in particular unintended creasing in the side wall, it is proposed that, during the procedure of preparation for upturning, a spacer provides separation between the roller and the segment in such a way that the roller is in essence in contact exclusively with the tire-building component. The roller therefore rolls along the tire-building component.Type: GrantFiled: October 21, 2008Date of Patent: August 28, 2012Assignee: Continental AktiengesellschaftInventors: Andreas Jungk, Martin Gerighausen

Patent number: 8211258Abstract: A tread for a vehicle tire, such as a pneumatic vehicle tire, is provided with an electrically conducting layer axially inside a portion of a first, radially outer rubber layer of the tread. The electrically conductive layer extends from a second, radially inner rubber layer of the tread on the radially inner side of the tread rubber material up to a ground contact surface of the tread. The rubber material of the electrically conducting layer and the rubber material of the radially inner rubber layer of the tread have a higher electrical conductivity than the rubber material of the radially outer rubber layer.Type: GrantFiled: October 6, 2008Date of Patent: July 3, 2012Assignee: Continental AktiengesellschaftInventor: Udo Frerichs

Publication number: 20120160423Abstract: A tread for a vehicle tire has an electrically conducting layer axially inside a portion of a first, radially outer rubber layer of the tread. The electrically conductive layer extends from a second, radially inner rubber layer of the tread on the radially inner side of the tread rubber material up to a ground contact surface of the tread. During the tire build-up, an accumulation of rubber material of higher electrical conductivity is built on a first rubber layer of higher electrical conductivity. The accumulation is formed into a ridge web and then less-conductive rubber is laid laterally next to the web, such that the web of rubber material reaches up to the ground contact surface in the finished vehicle tire. The web is shaped by forming rollers, by baffles, or by a forming ring with a corresponding shape.Type: ApplicationFiled: March 1, 2012Publication date: June 28, 2012Applicant: CONTINENTAL AKTIENGESELLSCHAFTInventor: UDO FRERICHS

Patent number: 8152475Abstract: In a method for controlling operation of a compressor, the compressor is shut off by a control device in order to prevent thermal damages when an estimated temperature value Ts calculated by said control device exceeds an upper threshold value Tmax while the compressor remains on or is allowed to be turned on when there is a need for compression and a lower threshold value Tmin is not reached. In order to be able to more accurately estimate the estimated temperature and increase the thermal availability of the compressor, the estimated temperature value Ts is indirectly and cyclically determined by means of a mathematical-physical model that characterizes the cooling and heating properties of the compressor.Type: GrantFiled: April 10, 2004Date of Patent: April 10, 2012Assignee: Continental AktiengesellschaftInventor: Kai Sorge

Patent number: 8110055Abstract: A self-sealing pneumatic tire has a sealing band (3) applied adheringly in the circumferential direction on the inner side of the tire and radially within the tread. A sealant (2) is applied to a carrier material (1). The carrier material (1) of the sealing band (3) is a foil on which the sealant (2) has been applied. The sealant, because of its intrinsic stickiness, adheres both to the carrier material (1) and to the inner side of the tire.Type: GrantFiled: February 18, 2009Date of Patent: February 7, 2012Assignee: Continental AktiengesellschaftInventors: Stefan Sostmann, Martin Welzhofer
