Abstract

The residual of an easy open can end is controlled by a band heater mounted on the anvil in conversion system tooling. The separation at closest approach of the score and anvil in the conversion tooling is altered as necessary by thermal expansion and contraction of the anvil as determined by the power supplied to the band heater. An electrical circuit supplies power to the heater and includes a thermocouple for maintaining the anvil at a set temperature. A loop control periodically diverts a finished end from the conveyor, measures the residual and adjusts power to the heater if necessary to bring the residual into specification.
