Abstract
An air removal and fastener extraction system for use in retreading tires is disclosed. The system includes a strap that is disposed over a splice region of the tread during precure retreading. A plurality of fasteners are inserted through the strap and across the splice. This securely holds the splice region intact, allows air to be vented during curing, and permits removal of all fasteners in a single pulling motion exerted on the strap after the curing process is completed.
