Rockwool Slitting, Turning and Feeding System for PU and Rockwool Panel Line | Novotek, Shanghai, China

Novotek's Rockwool Slitting, Turning and Feeding System for PU and Rockwool sandwich panel lines cuts rockwool slabs into strips, turns them and feeds them into the double belt of a panel line, where they are laminated with coil sheet.

Slabs of 2,400 x 1,200 x 100 mm or 1,800 x 1,200 x 100 mm are slit into strips in thicknesses from 50 to 250 mm. The strips are conveyed, swerved and overturned so the fibres stand upright, which increases panel strength. After edge milling and PU spraying, they are laminated with the coil sheet.

The system can be used on its own on a rockwool sandwich panel line or combined with a PU + rockwool line. The connecting edges of rockwool panels can be sealed with PU foam to add strength and insulation.

Key Features

• Automatic slitting of rockwool slabs into strips

• Edge milling of the strips
• PU spraying on the strips before lamination
• Can run standalone on a rockwool line or combined with a PU + rockwool line
• Rockwool panel connecting edges can be sealed with PU foam

Frequently Asked Questions

• What panel thicknesses and widths can it feed? It feeds panels from 50 to 200 mm thick (50/75/100/125/150/175/200 mm) and up to 1,000 mm wide, with a maximum of 10 rockwool strips.
• How fast does it run? It runs at 5 m/min for 50 x 2,400 mm strips and 3.5 m/min for 50 x 1,800 mm strips.
• Can it be used with a PU line? Yes. It can run separately on a rockwool panel line or be combined with a PU + rockwool sandwich panel line.
• What should I send for a quotation? Send your target panel thickness and width, rockwool slab size and density, required line speed, the existing or planned panel line it will connect to, and your site's ambient conditions.
