Automatic line for cardboard packaging production consists of 2 colours flexographic machine and rotary trimming machine.
The printing device is equipped by vacuum transporter which can afford height accuracy of final print. Diameter of printing rolls is 500 mm which allows printing on sheets up to length of 1450 mm.
Simple system of printing technology – tray with plastic faced rolls leads to production cost savings.
TPrinting rolls are coupled mechanically with ability of fluently adaptation during operation around and axially which helps to set the printing matrixs to accurate position.
Transportation part which links the flexographic machine with rotary trimming machine is disconnection able and allows good transport of cardboard to second flexographic machine, so as the possibility of independent printing, or independent trimming on trimming machine.
After printing operation is cardboard automaticly transported to rotary trimming machine, subsequent centering is processed. Right operation of centering is issued by well programmed controller. Electronic system continuously controls mutual rate and position of the flexographic printing machine rolls and rotary trimming machine rolls.
Rotary trimming machine equipped with the roll with diameter of 500 mm allows trimming the product with length up to 1550 mm and can be equipped with system of waste material depuration.
