Abstract
Apparatus for curing a tire repair wherein an electrical heater pad is placed against the repair area on the inside of the tire, and is supported by a flat air bag which lies against the inside of the tire, and is supported by a sausage-shaped air bag. Another electrical heater pad is placed against the repair area on the outside of the tire, and is held against the tire by another flat air bag which is held against the tire by straps passing around the tire cross-section. A buckle is shown which allows the straps to be pulled up as tight as possible by hand; the bags are then inflated to hold the heater pads firmly against the tire. The repair is then cured by passing currents through the heater pads.
Claims6
Apparatus for use in curing a tire repair, comprising an inner heater pad to be applied to the inside of the tire in the area of the repair, a core to be positioned within said tire to support said inner heater pad against the inside of said tire, an outer heater pad to be applied to the outside of said tire in the area of said repair, a flexible harness to be positioned to extend through the center of said tire and around the outside of said tire in the area of said repair, said flexible harness including a plurality of straps to be positioned around said tire with the center-line of each said strap approximately radial and a buckle including an opening to admit a loop of each strap, said loops being side by side, and a pin to be inserted through said loops, the length of said pin being greater than the combined width of said straps, an inflatable bag to be positioned between said harness and said outer heater pad, means for pressurizing said inflatable bag, and means for heating said inner and outer heater pads to cure said repair.
A method for curing a tire repair comprising the steps of:
- applying an inner heating pad to the inside of the tire in the area of the repair;
- positioning a core within the tire for supporting said inner heater pad against the inside of the tire;
- applying an outer heater pad to the outside of the tire in the area of the repair;
- positioning a harness including a plurality of straps around the tire with the center line of each strap approximately radial;
- passing a loop of each of said straps through an opening in a buckle whereby said loops are side by side;
- inserting a pin through said loops, the length of said pin being greater than the combined width of the straps;
- positioning an inflatable bag between the harness and the outer heater pad;
- pressurizing the inflatable bag;
- and
- heating the inner and outer heater pads to cure the repair.
