PERFORATING RULES
For business forms, corrugated, folding carton and labels industries.
Helmold offers the largest variety and best quality perforating rule to the business forms, corrugated, folding carton and label industries.
We use only superior high carbon steel in the manufacture of our perforating rule. The result is longer press life and fewer set-ups. Our advanced manufacturing process produces a clean, precise space which doesn’t require a secondary bevel to remove a burr. Helmold customers enjoy a tooth and space accuracy which is unsurpassed in the industry. Our perforating rule is available in virtually any combination of teeth and spaces, controlled depths, tempers, bevels, heights, cut lengths or coils. For wider perforation spaces than those indicated here, see the combination cut and crease rule section.
