38. Lambda – The Windowsystem Innovative, flexible, practical Processing

39. Processing Simple processing  Connection: crimp, punch, drill  Stable inner chamber  Optimized connections  Improved ability of turning  Coatable compound profiles  Easy change of series

40. Processing  Cutting tolerances +/- 1,5 mm  Improved ability of turning, small sashes, down to 350 mm  Slotted, self-leveling corner cleats: automatic leveling in height for a neat flush mitre, with minimal adjustment required (driving pin/nail home automatically levels profiles)

41. Processing  Easy to apply T-connectors with integrated gasket  Identical hole pattern for corner und T-connectors  All processing for corner and T-connections can be done by different punching tools as stationary punches, handpunches, multipurpose punches as well as drilling jigs  Reduce number of crimping knives required for the crimping of the frame profiles –> less change in tooling when using different frame geometries  Upgrade kits for several 1.0 punching tools reduce the necessary invest for fabricators who used 1.0  Delivery of mill-finished compound profiles and surface treatment done by the customers possible  Processing tools: stationary punches, hand punches, multipurpose punches and drilling jigs available
