Ads Professional machines for paper, cardboard, and film from Zielona Góra

Comprehensive solutions for the paper and packaging industry

We offer a wide range of used machines for paper, cardboard, and film processing: rotary and flat die-cutters, folder-gluers, laminating machines, programmable guillotines, quality inspection systems. We collaborate with leaders: Bobst, Heidelberg, Polar, Komori, Diana. Each machine undergoes a 145-point inspection including mechanical tests, calibration of positioning systems, verification of die-cutting and creasing quality. Savings when purchasing used machines range from 45-65% while maintaining production efficiency >85% of new machines.

Technical parameters verified before sale

We check the synchronization of the upper and lower die-cutter plates (±0.05mm at full speed), uniformity of pressure (300±20 tons across the surface), condition of cutting tools (knife height 23.8±0.1mm), precision of sheet feeding systems (±0.5mm positioning), quality of creasing and perforation, efficiency of waste removal systems, calibration of guillotines (accuracy ±0.1mm over a length of 1000mm).
