ABSTRACT:
A skin packaging machine for the vacuum application of a film over goods to be packaged including a microprocessor-based control. The skin packaging machine includes a film supply, an oven, a film-bearing frame, a base having a platen with a perforated surface, a blower or turbine for drawing a vacuum at the surface, and a variable speed motor for moving the frame from a position adjacent the oven to a position adjacent the perforated surface in order to apply the film to a package on the surface. The microprocessor-based control cooperates with an alphanumeric display to provide a sequential display of machine function parameters which may be individually set, such as the time duration of a particular function. The control arrangement further includes, in a test mode, means for sequentially displaying on the alphanumeric display the condition of sensors and switches.
