Frequently asked questions
Which roller attachment is best suited for punching ventilation slots in gravel stop trims?
The MASC Duo long-slot roller punches two parallel ventilation and drainage slots in one operation, making it specifically suitable for serial production of gravel stop trims in balcony and flat roof areas. It is designed to DIN standards, which ensures dimensionally accurate openings.
I want to punch two parallel drainage slots in one pass; which tool is recommended for this?
The MASC Duo long-slot roller is designed exactly for this purpose: Instead of a single row per pass, it punches two parallel rows of slots simultaneously, eliminating the need to pass the sheet metal strip through twice. The sheet feed occurs automatically when the crank is operated.
Can it also be used to efficiently produce chimney ventilation?
Yes, the production of ventilation openings on chimney flashings is one of the intended applications for the MASC Duo long-slot roller. Since both rows of slots are created in one operation, this saves time compared to two separate passes.
For which bead forming machines and material thicknesses is the roller suitable?
The attachment is available for hand-operated and motorized bead forming machines in sizes 20/25 and 26/32. It can process aluminum up to 1.0 mm, copper and zinc up to 0.8 mm, sheet steel up to 0.6 mm, and stainless steel (V2A) up to 0.5 mm.
Is the tool also suitable for the perforation of large-scale ventilation sheets according to DIN standards?
Yes, the perforation of large-scale ventilation sheets for roofs and facades is among its intended applications. The design in accordance with German industrial standards (DIN) ensures dimensionally accurate ventilation openings.
