Knives, Shears, Slitters, Automatic Positioning Systems and Tooling for the Slitting Industry


Dienes Corporation was founded in 1954 and has been operating from a modern 40,000 sq. ft. facility in Spencer, Massachusetts, USA, since 1977. Fifty plus employees design, manufacture and distribute the full range of Dienes products from knives to automatic positioning systems. From Spencer we service the NAFTA region of North America; Mexico and Canada. Our sales staff includes experts dedicated to serve customers in the nonwovens, paper and plastics markets.

Dienes Corporation, USA is part of the Dienes group which includes six facilities in Overath and Remscheid, Germany; Piliscsaba, Hungary; Kuala Lumpur, Malaysia; and Inowroclaw, Poland; and Spencer, Massachusetts, USA. For more information about the entire Dienes group visit www.dienes.de




Dienes Corporation

Dienes Corporation manufactures a complete line of ``Edge Trim Systems`` designed to maximize web usage by minimizing trim widths and waste management.

Edge Trim Systems

Our systems range from simple manually actuated devices to fully automated and computer-controlled positioning systems that can operate in a variety of environments and application without limitations on speed, material and operating web widths.

The versatility and customization capabilities of our ``Edge Trim Systems`` in conjunction with our state of the art engineering and manufacturing facilities enable us to scope, design, engineer, manufacture and service and application in the industry.

The ``Edge Trim Systems`` are specially designed to solve the problems of all areas of the industry, from plastics and film applications to paper and paperboard operations, as well as non-woven and textiles industries. Our systems have also been successfully installed in rubber industry applications and aluminum and foil processes.

Please contact us with your specific needs and we will design a custom solution to your application that will solve your trimming issues, increase your productivity and quality of finished goods, while realizing substantial savings in operational costs and waste management.



The majority of Automatic Slitter positioning systems sold are justified on time saved in making location changes, and knife placement accuracy. Dienes` QUIK-SET positioning system maximizes time savings by moving all knife holders simultaneously, with the benefit of high accuracy placement via computer control.

QUIK-SET Automatic Positioning Systems

In-line operations, such as extruders or paper machines, require rapid holder set-up changes. Dienes` QUIK-SET system can change all holders in 5 seconds with a position accuracy of +/-0.012``.

QUIK-SET systems are available with any Dienes shear or crush cut holder. Shear cut systems require a motor driven female knife.

Features:

  • simultaneous positioning of holders
  • computer location control
  • linear bearing and rail guiding
  • touch screen control
  • industrial PC
  • positioning software by Dienes
  • production control download capability
  • small installation envelope

Benefits:

  • minimized holder set-up time
  • high positioning accuracy
  • touch screen control
  • reduced scrap generation
  • increased profits
  • hands off changes with increased safety
  • will fit most machine frames

Rotary Shear Knives

Dienes Corporation offers a wide range of knife designs and material compositions to meet your slitting requirements. Over the years Dienes has developed a variety of alloy grades to precisely match knife composition with the increasing number of modern day slitting applications (See Technical Bulletin 1010-002).

High speed and tool steels are specifically formulated to maximize wear resistance and toughness depending on the material being slit. Tungsten carbide slitter knives are available in both solid and composite configurations. Additionally, slitter knives made from the particle metal group offer extremely high wear resistance.
Our slitter knives are manufactured to exacting tolerances and finishes. Thickness tolerances can be held within ±40 millionths of an inch, parallelism and flatness within 80 millionths of an inch. For special applications, knives can be supplied with a thickness tolerance of ±20 millionths inch. The lateral (side) faces are available in ground, lapped, or polished finishes.

Whatever your need, our Application Engineers can recommend a design and material composition to satisfy your slitting requirements. If you know what you want, Dienes can manufacture slitter knives to your specifications. In either case, you can be assured of getting a slitter of the highest quality.

Shimless Tooling Sets

Conventional tooling is usually manufactured to fractional (1/32`` 1/16``, 1/8``, 1/4``, etc) or decimal (.031``, .047``, .062``, .093``, .109``, .125`` etc) increments, and machined to ANSI standard (±.0002``) thickness tolerances. Using conventional tooling requires the use of plastic shims, which have the tendency to pick up dirt or fold over. The combination of the thickness tolerance of the knives and spacers in conjunction with the usage of plastic shims, often caused problems in maintaining proper clearances, achieving tighter strip width tolerances, and avoiding cumulative tolerance errors. This resulted in shorter tool life and the need for re-sets.

Shimless tooling, having a thickness tolerance of ± 40 millionths of an inch (±0.001 mm) and manufactured to .001`` increments allows complete flexibility, mathematically, in grouping tooling without using plastic or steel shims. Typical shimless spacer complements use spacer sizes, such as .1005, .100, .101, .102, .103, 106, .110, etc., or .0505, .050, .051, .054, .058, etc. Standard tooling packages are designed to achieve strip width increments of .001`` and clearance increments of .0005``. However, there are also systems, which utilize clearance increments of .0001`` and strip width increments of .00005``. Shimless tooling is always supplied with a WINDOWS™ software program, which solves the problem of calculating shimless setups.

The major benefits of shimless tooling are:

  • Exact and even clearances
  • Elimination of cumulative tolerance errors
  • Less chance of setup errors (re-sets)
  • Minimum/reduced knife edge stress as a result of a balanced setup
  • Same slitting results from operator to operator (important for a multiple shift operation).
  • Computer tells the operator which steel spacers and knives to use, for any given setup, to obtain the correct strip widths
  • Achieving tighter slit width tolerances
  • Virtually burr free strips
  • CamB_5 advanced software that offers various input and output options
