Oliver Rubber Introduces Envelope Spreader For 16-58” Retreads
Michelin North American subsidiary Oliver Rubber recently introduced a new envelope spreader for use in the retreading process, which helps mechanically facilitate enveloping prior to curing. With a push of the foot pedal, Oliver’s 1137 Envelope Expander uses preset adjustments to mechanically stretch the envelope to the optimum diameter, thus minimising envelope stretch and in turn increasing envelope life. The new Oliver spreader was developed and manufactured by the company’s Salisbury Machinery Division in Salisbury, North Carolina.
