Integrated printing solution for converting lines

Research shows that women are more likely to trust and stay loyal to sanitary napkin brands with printed designs on the inside. Until now, the options for brand-owners have been limited to manufacturing plain sanitary napkins, or relying on a costly outsourced supply of printed material with lead times of several weeks.

Now, in conjunction with a global brand owner, TRESU has developed a flexo printing solution, customised for integration into napkin converting lines. Fully automated and built to the highest standards of safety, this unit offers the flexibility to apply unique multi-coloured designs in perfect register, inline without compromise in production speed.

Based on TRESU's 35 years of flexo engineering expertise, the unit comprises up to four water-based colours, a hot air dryer and a register system. The printing solution is contained within a single module, offering both a compact footprint and an operator-friendly design.

Located at point of embossing, the register system ensures synchronisation of the printed pattern with the crease in the centre of the napkin, at speeds of up to 400 metres per minute (approximately 2000 pieces per minute). Using the converting machine interface signals as point of reference, the control module provides a direct loop to the servo motors to ensure accuracy on-the-fly, throughout the production run.
