Although no material is present in this illustration, it can be readily seen that the roller ball tracks in the central area of the machine are at different levels which is to suit a truncated profiled
roofing or cladding panel. The plastic coated sheets are driven towards the tooling units by the roll forming machine and as the sheet reaches its measured distance the line stops for 2 seconds while the 42 punching
tools operate and punch the edge fixing/bolt holes. The line continues to feed the material towards the guillotine station where the truncated and punched panel is sheared off.
