Cutting Bevels
CF Centre Face
(Centre Bevel)

The CF-bevel is the most commonly used symmetric cutting edge for standard cardboard. Standard edge angle: 53° (others on request)
SF Side Face
(Single Bevel)

This type of cutting edge is particularly suitable for cutting hard materials (gaskets, displays and close shapes). The minimum counter bevel facilitates a right angled, straight cut.
CFDB Centre Face
Double Bevel

This type of cutting edge reduces the cutting force required when cutting hard and/or thick materials, such as glass fibre reinforced laminates, leather, cork, rubber, jigsaw puzzles, corrugated board, plastics, plywood, etc.
SFDB Single Face
Double Bevel

The SFDB profile offers the same advantages as the CFDB when cutting thicker materials. SFDB has the advantage that the substrate is left with a square 90° cut edge and all the distortion from penetration is left on the material waste. Not available in "G" execution.

Supreme Dust Killer

The Supreme cutting rule was originally developed for the label industry with the goal to restrict the build-up of adhesive on the cutting edge. This type of rule is now used successfully in a variety of applications. It has gained reputation for dust-reduction for boards with increased recycled fibre content. Supreme-coating significantly reduces mechanical wear and tear on the cutting edge thereby considerably increases the cutting die lifetime.

In the same way the required press force is substantially lowered, which contributes considerably to extending the life of expensive automatic platens.

Product Information:

By means of a special process the cutting bevel of the Supreme rule is coated with a thin anti-friction-film which fills the microscopically small pores and marks on the cutting edge and thereby adds to the smoothness of the bevel surface.
Supreme coated rules are offered in Universal and Universal 60.

Special Characteristics:

  • dust-reduced cutting
  • reduction of press force thus less wear on die cutting equipment
  • reduction of friction between cutting edge and cutting material
  • substantially increased service life of the die

TOP

This all-purpose steel rule from BÖHLER offers good bendability and is suitable for low runs.
Used for:
Cardboard, corrugat ed board, …

UNIVERSAL

has the excellent bending properties of soft steel, with the long service life of an extra hard cutting edge and can, therefore, be universally used.
Used for:
Cardboard, corrugated board, labels, post cards, …

UNIVERSAL 60

combines the body hardness level of the TOP rule with the advantages of an induction hardened cutting edge. This means high rigidity, outstanding wear resistance and long service life.
Used for:
Plastic, thin gaskets, foils, puzzles, …

STANDARD CREASE PROFILES

PLASTIC-CREASE


Böhler Plastic-Crease is a special type of cut-crease rule to produce creasing lines in plastic sheet material (PET, PVC, etc.).

Conventional Creasing of Plastics:

  • Local reduction of folding resistance by decreasing the material thickness, no creasing matrix is used.
  • Creased parts may bulge, which create problems in automatic folding and gluing machines.
  • Hot-creasing technology gives better results, but is expensive.
  • Creased plastic sheets may develop micro-cracks upon folding, visible as milky shades in the material.

Plastic-Crease:

  • Very localised reduction of folding resistance prevents micro-cracks and “whitening” of the creasing track.
  • Plastic-Crease creates less material displacement, creased parts therefore remain flat.

Types currently available:

UNIVERSAL CF, 2pt, in lengths of 1 m
Cut/Creasing height combination:
23,75/23,35 · 23,70/23,30 and 23,60/23,20
Pitch: 25 teeth/inch (tpi)

COMBINATION (CUT-CREASE) RULES


Benefit: no need for inserting individual parts of cutting and creasing rules. BÖHLER cut-crease rules are produced in standard punched (CF), or in flator round machined executions for high-quality demands (CF/FT and CF/SR).

PERFORATING RULES


BÖHLER perforating rules are available in a wide range of various thicknesses and tooth/gap combinations. The spacing is usually given in mm. On request, we also manufacture in point and inch spacings. Minimum gap width is defined by rule thickness.

SPACER RULES


Spacer rules fill gaps between steel rules and wider laser cuts within the die board or backfill unwanted laser cuts within an existing die. The rules show a square cross sectional profile.
BÖHLER spacer rules are available in all common wood sizes used in the die making industry.
