Patent number: 11141883Abstract: The invention is directed to an apparatus for making a finished rubber mixture which includes a reactive additive. The apparatus includes a tandem mixer with an upper machine having an upper mixing chamber and a lower machine having a lower mixing chamber. The lower mixing chamber is larger than the upper mixing chamber and there are rotors disposed in each mixing chamber. Mixture components are introduced into the lower mixing chamber via a loading shaft of a loading unit. The loading unit has at least two metering devices, a cutting or preheating unit connected upstream of a metering device and a first conveyor belt to the loading shaft. All conveyor belts of the apparatus can be switched on and off automatically, such that mixture components weighed in can be held in a “wait position” thereon.Type: GrantFiled: June 11, 2018Date of Patent: October 12, 2021Assignee: Continental Reifen Deutschland GmbHInventors: Frank Stefan Steiner, Fabian Dettmer

Patent number: 9034980Abstract: A pneumatic tire for a commercial vehicle with a tread, wherein at least the part of the tread which comes into contact with the road contains a sulphur-vulcanized rubber mixture. The sulphur-vulcanized rubber mixture contains 90 to 50 phr (parts by weight, based on 100 parts by weight, of all of the rubbers in the mixture) of natural rubber, 10 to 50 phr of at least one polybutadiene having a glass transition temperature Tg of ?110 to ?65° C. and 5 to 50 phr of at least one aliphatic and/or aromatic hydrocarbon resin having a softening point (ring and ball to ASTM E 28) of 0 to 150° C., and a mean molecular weight Mn of less than 2000 g/mol and a polydispersity D=Mw/Mn of 1 to 5.Type: GrantFiled: April 22, 2013Date of Patent: May 19, 2015Assignee: Continental Reifen Deutschland GmbHInventors: Carla Recker, Philipp Koelle, Thomas Kramer, Christoph Jocher, Thorsten Torbruegge, Fabian Dettmer, Norbert Daldrup

Publication number: 20090054551Abstract: The invention relates to a rubber mixture that can be cross-linked by sulphur and contains, in order to achieve low-temperature flexibility and high-temperature rigidity, at least one diene rubber, between 5 and 150 phr (weight parts in relation to 100 weight parts of the total rubber mass) of at least one type of soot with an iodine adsorption index >65 g/kg and a DBP index >90 cm3/100 g, and between and 150 phr of a type RAE (residual aromatic extract) crude oil fraction as a softener. The weight ratio of the soot to the crude oil fraction in the mixture is 1:1 to 1:10.Type: ApplicationFiled: May 5, 2006Publication date: February 26, 2009Inventors: Steffi Meissner, Hajo Weinreich, Fabian Dettmer, Jurgen Wagemann
