Glue Tab Cutting Systems and Components

Glue Tab Cutting and Components for Soft Anvil Cutting Systems

Over 50 years ago, Sauer System pioneered the soft anvil glue tab cutting technique, which is the industry standard to this day. When all Sauer System brand components are used together, installed, corrected and used properly, the system is designed to remove 100% of glue tabs.

Upper and Lower Glue Tab Heads

Sauer System upper glue tab heads are available in yoked and manual set designs. Each head has a working surface that is knurled on the outer diameter, is stamped in 1/4″ increments to help the operator set it up, and has t-bolt assembly to accommodate male slotting blades and tab knife holders.

When needed, special application requirements can be met. Examples include heads with wider shoulders for wider tab knife holders and special index stamping requirements.

For applications involving yoked and manual sets, lower slot anvil systems are also available. The base head, pinch blade, spacer, thick blade, and anvil cover are included with assemblies.

Both heads are made from the finest materials to prevent fatigue and include a dowel pin to ensure circular bore alignment.

Glue Tab Cutting Knives

Successful glue tab cutting requires a well-designed tab knife. Tab knives from the Sauer System are an essential component of the system and have particular design advantages.

Knives feature an angled edge notch that performs a precise pinch cut rather than a smash-and-tear action on the 3/32″ blade.

Key Advantages:

  • The height of the beveled edge is precisely controlled
  • Knives have a tapered edge so they can mount against the male slotting punch without a gap
  • Unique 8 tooth design allows for minimal cutting pressure and precise cutting depth
  • Knives are fully hardened to a minimum of 40 Rc
  • Popular knives are conveniently packaged in kits that contain 25 left-handed and 25 right-handed knives

3/32" Pinch Blades

An integral component of effective glue tab cutting is a well designed 3/32” blade. Sauer System manufactures 3/32” blades from the finest spring steel to exacting tolerances, designed for consistent pinch-cutting of glue tabs. Our blades are designed to last longer than competitors’ blades, necessitating fewer replacements and providing greater overall value.
