Process and assembly to heats shape foil e.g. packaging foil bearing markers identifiable by sensors along the process

摘要

In a process to shape foil heat-shaping process, a foil (10) bearing a marker (9) is introduced into a forming tool or is placed on a carrier (5) and transported (11) first to a heater station (1) and then to a forming station (3). The transporter entry point has a regulator sensor (14). A sensor (17) is placed at the forming station inlet and a further sensor at the outlet (18). The signals generated by the sensors determine the operation of foil positioning actuators (19). Also claimed is a commensurate operating process.
