In the subsequent packaging workplace, individual tapes they are sorted by width, taped and stored in a bundle on a pallet. There are scrolls protected against weather effects according to the customer's request (stretch film, anti-corrosion paper).
The working speed of the line is max 80m/min. For longitudinal division we use cutting edge blade knives that are made from cemented carbides (80% WC).

When cutting into boards, punching of circular holes can be ensured of different diameters (10 mm, 11 mm, 12 mm, 22 mm).
The cut boards are placed on a pallet, taped and wrap in anti-corrosion paper at Coil slitting Center.
