Slitting Lines and Cut to Length Lines

hpl-Neugnadenfelder Maschinenfabrik GmbH designs and manufactures cut-to-length and slitting lines as complete systems for all ferrous and non-ferrous metals as well as special materials with metallic or coated surfaces. hpl focuses on slitting shears for hot rolled steel and shears for thin strips, offering our customers best quality and highest possible productivity.
The decisive factors for an uncompromising quality in the cutting process of cold rolled strips are: adherence to narrow cutting tolerances, burr-free cutting as well as the precise recoiling of the cut strips. The cut-to-length and slitting lines manufactured by hpl-Neugnadenfelder therefore consist of highly specific precision shears especially designed for cutting thin metal strips all the way up to metal foils.
The core element of hpl slitting shears is the knife shaft. All knife shafts are manufactured entirely in-house, enabling them to offer their customers unsurpassed quality:
  • Highest precision of the knife shaft bearing
  • Lower knife shaft infinitely variable in axial direction
  • Knife shaft adjustment by servomotor via low-backlash, pre stressed ball screws
  • Automatic opening and closing of the front shear housing part of standard equipment
  • Extremely high concentricity and plane parallelism
The high degree of precision in hpl slitting shears enables line
speeds of up to 1,000 m / min at constant quality.
Their new development in the cut-to-length product range is called
flying cross-cut shears. This kind of shears avoids stopping the strip
during the cross-cut process, thus allowing a continuous line
operation and a corresponding productivity increase.

Each line is individually planned and designed based on the conditions on site and the product mix of the customer.

These customer specific line concepts include:

  • Loop pits, braking units and recoilers
  • Direct strip spooling, incl. guide mechanism (starting from 1 up to required number of recoilers)
  • Alternating recoiling of single strips, incl. guide mechanism (starting from 1 up to required number of recoilers)
