AUFBAU UND HAERTEN EINES NICHT DEHNBAREN BANDES FUER FAHRZEUGREIFEN

摘要

The apparatus incorporates a rigid cylindrical form or mandrel on the outer surface of which a belt structure is built, between a pair of end dams. The radially inward surface of the mandrel is cylindrical and provides a large unobstructed cylindrical opening therethrough. The mandrel is constructed of a multiplicity of axially extending segments which are rigidly locked to and extend between a pair of end rings which provide the edge dams. Upon completing the belt structure, the belt structure together with the rigid mandrel are inserted freely into an annular channel between an outside and an inside curing assembly. The inside curing assembly includes a single cylindrical diaphragm expandable radially into contact with the cylindrical inner surface of the mandrel solely to apply curing heat thereto. The outside curing assembly includes a multiplicity of segments which are moved radially inwardly to engage the outer surface of the belt structure in response to an increase in pressurized heating fluid in a chamber defined by a cylindrical elastomeric diaphragm engageable with the cylindrical outer surface of the multiplicity of segments. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.
