Abstract
An apparatus and method for applying a stabilizer ply to a tire building drum and more particularly an apparatus and method for cutting and applying the stabilizer ply material and specifically an apparatus for cutting the stabilizer ply material between cords disposed therein and correcting for variations of the cord angles during the application process in order to provide an improved splice between the leading and trailing edges of the stabilizer ply material.
Claims1
A method for severing a length of elastomeric material having two outer sides and having reinforcing cords using a knife means having a notch therein, comprising the steps of:
- a. pivotally plunging said knife means into said length of elastomeric material at a point approximately half way between the edges of said length thereby creating an edge;
- b. engaging said edge of said length of elastomeric material with said notch;
- c. displacing said knife means through said length of elastomeric material in a first direction through the first outer side of said length of elastomeric material;
- d. replunging said knife means into said length of elastomeric material at a point proximate to said first plunge;
- and
- e. displacing said knife means through said length of elastomeric material in a second direction through the second outer side of said length of elastomeric material.
