A fast downstream centre for reinforcement screw driving, drilling and routing cut-to-length profiles for window and door manufacturing with and without steel reinforcement. Portal design for high profile cross-sections and process-optimised throughfeed. Additional efficiency through parallel processing by external reinforcement screwdriver system. Work sequence as needed, either from the left towards the right or the reverse. Infeed with motorised, continuously adjustable gripper. Lifting function for gap-free loading of the feed magazine. Profiles are guided on rollers to ensure gentle treatment of the profile and protective film as well as completion of long machining operations without re-clamping. Simultaneous reinforcement screw driving through external screw driving station. Internal gripper avoids damaging the profiles. Integrated measuring sensors for part length monitoring. Outfeed for parts via discharge table. Industrial PC with Windows operating system. Barcode scanner. Options: outfeed for parts via a belt conveyor protects profiles and offers different capacities; additional reinforcement screwdriver units for multiple types of screws; upending unit for profiles that are difficult to clamp; reinforcement screwdriver unit with controlled servo drive for screw tightening with a gentle touch; noise abatement enclosure.
