Knife Holders

The absolutely precise guiding of knives to achieve long service times requires considerable expertise in the development and design of knife holders.

Dienes' long-standing research efforts have led to knife holders that are precisely adaptable to all slitting applications. Preloaded, caged ball bearing sets, with zero clearance, support both the vertical and horizontal stroke travel of the holders. Dual caged ball bearing sets on the vertical stroke prevent torsion or side twist of the knife blade lower head. A preloaded, caged ball bearing supports the knife blade on the lower housing also stopping blade twist.
 

  1. Precise adjustment of knife depth.
  2. Reliable and exact positioning of the knife with integrated 360° knife guard.
  3. The positioining aid is so simple and brilliant that it is protected by patent. The Dienes Knife Pilot Easy Set (ES Tab): low cost, high precision. The worldwide standard for manual systems.

The bearing cage guided knife holder shafts, manufactured to the highest level of precision, guarantee a torsion free and vibration dampening operation. Compared to less complex solutions, this allows the user to experience the Dienes high precision slitting technology to its utmost extent.
