The machines are equipped with a complete system of precise vetical and horizontal adjustments and labelling head angle adjustments. The technical solutions we have applied also allow us to mount a printer for additional information, e.g. expiry date, batch number, etc. Machine control is carried our by a faultless industrial PLC, enabling precise, repeatable operation free from external disturbances. Operator communication occurs via a large, easy to read touch screen display which significantly accelerates the selection and change of parameters. Powerful stepper motors used to drive the heads allow for high speeds of label feeding with low scatter, which substantially affects both high efficiency and good qualiľy of labelling.
