Abstract (en)
[origin: US4682038A] During the monitoring of a web (10) especially a sheet of packaging material (foil), (photoelectric) sensors are used for monitoring the material and positioning. These are accommodated in or on a housing (12) which can be handled as an independent unit. Several monitoring systems for sensing different features of the web (10) or of a tear-open strip (25) are provided in the housing on both sides of a slit (13) open on one side.
