Apparatus and gauges for use in measuring the diameter of a buffed tire in relation to a particular matrix

摘要

Gauges are provided to measure the diameter of a buffed tire to determine whether with the addition of a predetermined amount of uncured rubber thereto by an extruder builder, a predetermined mold or matrix can be used, whether additional rubber will have to be applied by the builder before that matrix can be used or whether the buffed tire should not be used with that matrix.
