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 reliably minimizing 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 NC.
The new Oliver spreader features:
-
Installs under the monorail.
-
Robust frame and mechanism.
-
Synchronized arm movement.
-
Manually adjustable height and tilt.
-
Single cylinder actuation.
-
Double-sided envelope fingers and dual footvalves for easy access and operation from either side.
-
Easily removed doors for cylinder and mechanism maintenance.
-
Manually selected, quick adjust, five-position stretcher arm design.
-
Operation diameter range from 16" minimum (fully retracted), to 58" maximum (fully expanded).
