Tire bead covering apparatus

Apparatus for applying an elastomeric cover stock to an annular tire bead comprising, lower carriage means for supporting the tire bead, upper carriage means mounted for movement to clampingly engage the tire bead against said lower carriage means, means for rotationally driving the tire bead, roller means on said upper carriage means for adhering the cover stock to the tire bead adjustably positioned with respect to the tire bead and adjustably resiliently biased thereat, fold roller, means having two opposed rollers, one of said fold rollers being slip mounted to permit variation between the angular velocity of said opposed rollers, and stock feed and severing means supplying a length of the cover stock sufficient for wrapping about the circumference of the tire bead.

Apparatus for applying an elastomeric cover stock to an endless tire bead comprising, lower carriage means for supporting the tire bead, drive roller means for rotating the tire bead, upper carriage means mounted for movement to clampingly engage the tire bead against said lower carriage means, roller means on said upper and lower carriage means for adhering said cover stock to the tire bead, feed means having a shuttling slide plate with a cutout which advances to straddle said drive roller means for positioning the medial portion of said cover stock in engagement with said drive roller means for joinder to the radially inner surface of said tire bead during the rotation thereof, and severing means for cutting moving cover stock to a length sufficient for wrapping about the circumference of the tire bead.

Apparatus for applying an elastomeric cover stock to an endless tire bead comprising, lower carriage means for supporting the tire bead, means for rotating the tire bead, upper carriage means mounted for movement to clampingly engage the tire bead against said lower carriage means, roller means on said upper and lower carriage means for adhering said cover stock to the tire bead, feed means positioning the medial portion of said cover stock for joinder to the radially inner surface of said tire bead during the rotation thereof, and severing means for cutting moving cover stock to a length sufficient for wrapping about the circumference of the tire bead having a knife and a shear bar positioned in the direction of cover stock travel relative to said knife such that the tendency of the moving cover stock to deflect said knife brings said knife in contact with said shear bar.
