Abstract

1335859 Tyre conditioning HOFMANN GmbH Gebr [trading as HOFMANN KG Gebr] 14 June 1971 [3 Dec 1970] 27760/71 Heading B7C Apparatus for working a tyre mechanically, to reduce the deformation of the tyre and the formation of flat spots resulting from heating and cooling of the tyre under load, comprises three rotatable rolls 2, 3 arranged in a vertical plane in an isosceles triangle configuration, the upper roll 3 being mounted on a hinged arm 6 such that it can be displaced downwardly towards the rolls 2 in order to alter the pressure applied by the rolls to the tread of a tyre 1 mounted between the rolls, the pressure on the arm 6 being controlled by a piston-cylinder device 5 pivotally connected to the arm and to the base of the apparatus, guide rolls 7, 8, 10 and 11 being provided to prevent lateral movement of a tyre mounted in the apparatus, and a motor 9 being provided to drive one of the rolls 2 thus rotating and working the tyre. More than one roll may be driven, and the rolls may be arranged in a horizontal plane. The guide rolls 7, 8, 10 and 11 may be movably mounted to accommodate tyres of different sizes. The apparatus may alternatively be such that the tyre is stationary while a rotatable three-roll assembly is rolled around the tyre tread at a constant pressure. During working, heat may be applied to the tyre from an external source.
