Glue Tab Cutting Systems and Components

Sauer System pioneered a soft anvil method of glue tab cutting over 50 years ago that remains the industry standard today. 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 is stamped in 1/4” increments to assist in operator set up, knurled on the outside diameter working surface, and includes t-bolt assemblies to hold tab knife holders and male slotting blades. When needed, special application requirements can be met. Examples include heads with wider shoulders for wider tab knife holders and special index stamping requirements.

Lower slot anvil systems are also furnished for yoked and manual set applications. Assemblies include the base head, pinch blade, spacer, thick blade, and anvil cover.

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

Tab Knife Holders

Sauer System manufactures a wide range of tab knife holders and clamp blocks. Custom holders can be manufactured to meet special application needs. We manufacture our tab knife holders to precise dimensions to ensure proper fit on the head.

  • Clamp blocks are sold separately and are heat treated for longevity

Tab Knives

A well-designed tab knife is a crucial element of successful glue tab cutting. Sauer System tab knives offer distinct design advantages and are an integral part of the system:

Knives have an angled edge notch that performs a clean pinch cut against the 3/32” blade, not a smash-and-tear operation.

  • 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


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.
