Abstract
The present invention relates to a replaceable pulley lagging for attachment to wing pulleys and includes a backing member having a shape which conforms to the contact bars of each of the wings of the wing pulley. These backing members have an adhesive and an elastomeric member vulcanized thereto along the length thereof for contacting an endless conveyor belt disposed around a wing pulley. The replaceable pulley lagging devices can be slid onto or off from the contact bars of the wing pulley. A method of forming these replaceable pulley lagging devices includes using an apparatus to push the backing member against an elastomeric substance in a mold and hold the backing member and elastomeric substance in the formed position until it can be vulcanized in an autoclave or the like.
