Technology CPUs: Technology Template "Flying shears"
This technology template helps you realize an "Flying Shears" or "Flying Knife" using a Technology CPU.
A fed web is to be cut to defined lengths with a Technology CPU. Flying shears are to be used.
“Flying shears” enable the processing of material without having to interrupt the material line. The available processing time depends on the velocity of the material line and on the length of the distance which can be moved by the shears.
The "Flying shears" consist of the shears attached to a travel range. The shears synchronize to the material line. If the shears are synchronous the cut is performed.
After the cutting process, the shears disable the synchronization and return to the starting position.
The cuts are either performed at definable distances or they are specified by print-marks on the material line.
