Infeed section

In the infeed section the top and bottom metal covering layers for the sandwich panel are unwound from the coils. The top band and bottom band are then further processed to suit the customer order. There are different types of motive, lines, profiles and many other features.
One form of special processing on the bottom band is, e.g., the stamping of a cassette (sectional door), the bonding of a film (lamination for roof elements) or cutting out certain areas of the metal sheet. The related processes for the top and bottom band are entered in the control system.
