Paper drilling is a technique used in trade binderies for providing large quantities of paper with round holes. The paper can be processed as loose leaves and in brochures (stitched, perfect bound). The holes usually serve for storage (filing), sometimes for decorative purposes.

Terminology[edit]

Paper drilling describes a technology for providing paper with round holes. For this purpose paper drilling machines are used. Paper drilling machines is the generic term for manual, motorised and fully automated paper drills.

Paper drilling machine

Paper drilling system describes an automated paper drilling machine usually integrating several production steps into one continuous workflow. The phrase paper drill is used as well for paper drilling machines as for the tools used for paper drilling.

Technology[edit]

Paper drilling is a method to drill round holes into paper and other materials. For this purpose hollow paper drill bits are clamped into a driven spindle which drills into the pile of paper. Paper drill bits are available for different hole sizes and in different coating qualities. Unlike hole punching, where only one or a few sheets may be processed, a large number of sheets can be processed with a paper drilling machine. Depending on the type of paper drill either the paper drill bits are lowered into the pile or the table is lifted. Paper drilling machines can be equipped with a different number of spindles which are each built into one paper drill head. The range starts with one- and two-spindle paper drills for small volumes and office purposes and reaches up to paper drilling platforms with more than 20 spindles / paper drill heads.

Applications[edit]

Applications for paper drilling are e.g. file holes for different ring binders, loose leaf collections, rows of holes for wire comb binding and tags. Many products processed on a paper drilling machine are stationery. Additionally catalogues, manuals and brochures are drilled on a paper drilling system to be able to file them in a binder. Sometimes drilled holes are used for decorative purposes. Additionally to different stock types - e.g. offset paper, bond paper, glossy paper, coated paper - a modern paper drilling machine can drill many other materials like plastic films, cardboard, foils etc.

Some casinos use a paper drill to deface used decks of playing cards, a process known as canceling. Cards are canceled so that they cannot be marked by cheaters outside of the casino and surreptitiously brought back into play.

Users of paper drills[edit]

Paper drilling machines are used in trade binderies, commercial print shops with finishing department, in-house print shops and copy shops. Depending on the volumes these companies operate many different types of paper drilling machines - from simple one- and two-spindle hand operated table top paper drills to standard motorised four- spindle paper drilling machines and fully automated, integrated paper drilling systems. These high performance paper drills can run in-line with other finishing equipment.
