The hardened and surface treated profile rollers of the cassettes are pre-set to material gauges of between 0.5 - 0.7 mm in the factory (except for special or facade profiles they may be set to either 0.6 - 0.8 mm or 0.8 - 1.0 mm). The machine is equipped with a PLC to automatically process material in various lengths and quantities. Operator entries are defined via a menu-driven touch panel. For conical profile shaping, a separate sub-menu is provided on the touch screen. Here, the operator can enter the necessary measurements for short width A, long width B as well as the panel’s length directly via a touch screen that is installed on the controller. From these entries the controller calculates the settings for the inclination of the cassette on the adjustable side. For this purpose, a hand wheel adjusts the cassette using a spindle in accordance with the specified value and it is then manually moved into the starting position. The conical profiling mode is only available for single cycle profiling operations. I.e., when the profile was run out of the machine, the movable cassette on the adjustable side must first be manually retracted to the starting position. Thereafter the next panel may be obliquely cut and profile shaped.
Profiling from a coil requires that the desired length and the item count are entered first via the touch panel. In the machine, manually fed strip material is transported by driven transport rollers. When the programmed length is reached, the frequency converter controlled drive is stopped and the crosscut shear executes an automatic cut. The overshoot, i.e. the tolerance in length is about 1 - 2 mm. In automatic mode, the next strip is started automatically. In single cycle mode, the operator is responsible for the restart. When the last profile has been cut from the strip, the material feed may be stopped by means of the clutch lever before the strip is removed manually from the infeed area.
