Abstract

PURPOSE:To measure the thickness of a pipe without damaging foil at all by calculating the foil thickness automatically by using the number of turns of an auxiliary roll, the radius of the auxiliary roll, and the number of turns of a foil take-up or payoff reel. CONSTITUTION:The auxiliary roll 1 contacts the foil B and is rotated in synchronism with the take-up or payoff speed of the take-up or payoff reel 3. An auxiliary roll rotational frequency detecting means 2 detects the number of turns of the auxiliary roll 1. A reel rotational frequency detecting means 4 outputs a detection signal every time the foil take-up or payoff reel 3 makes a specific rotation. An arithmetic circuit 5 calculates the thickness of the foil B from those detection outputs and the radius of the auxiliary roll 1 and a display means 6 displays the foil thickness.
