THICKNESS MEASUREMENT DEVICE FOR FOIL MATERIAL

摘要

A thickness measurement device for foil material having a preliminary sensing element in front of the actual measurement gap, which reacts when there is an increase in the thickness of the transported material and if necessary swings the measurement system away from the transport plane. This prevents blockages in the transport system and damage and misadjustments in the measurement system. A triggering mechanism working in conjunction with the preliminary sensing element can be so designed that the swinging movement does not take place until a specific pre-set force is reached. After the operating problem has been put right, the measurement system is automatically returned to its original position.
