f.PLC Control System
Control the quantity, punching position & cutting Length automatically, and setting parameters for auto web/flank size changing
Two options for cut-to-length control
Cut-to-length for Pre-cut, the profile edge would be spring back a little/ the min. product length is 2meters
Cut-to-length for post-cut, the profile edge would be much better / the pre-cut device is to cut-off the flat sheet when change coil only
