Abstract
Abstract Abutting edges of various plies wrapped about a tire building drum in the assembly of unvulcanized tire components are spliced together with a hand-held tool which features a pair of freely rotatable, oppositely slanted wheels mounted so that the angular peripheries of the wheels cooperate with the slanted mounting to urge adjacent ply edges together as the wheels are moved straddlingly along and on either side of the two abutting edges; the tool desirably and additionally featuring means for imparting heat to said wheels so that the unvulcanized stock is softened, enhancing the merging together of the stock edges as urged together by the hand pressure transmitted to the stock by the wheels.

Claim 13
Dependent Claim
14 words
means for electrically heating said wheels, said means being mounted proximate said wheels and,
Claim 14
Dependent Claim
14 words
means for electrically heating said wheels, said means being mounted proximate said wheels and,
Claim 15
Dependent Claim
40 words
means for inducing flow of electricity in said means whereby the heat of the wheels temporarily softens the material to thereby improve mixing of the respective materials in said marginal edges while gradual cooling thereafter hardens and fixes the splice.
Claim 16
Dependent Claim
40 words
means for inducing flow of electricity in said means whereby the heat of the wheels temporarily softens the material to thereby improve mixing of the respective materials in said marginal edges while gradual cooling thereafter hardens and fixes the splice.
