Two vertical cutting units trim the long block or the short block to the required width

IS-BA trimming machine

The maximum trimming length per cutting unit is 200 mm.

  • Operator positions cutting unit by means of a hand wheel (optionally motor-driven)
  • The position of the cutting unit is separately indicated as digital readout
  • Utilisation of teflonized bindings for a better guiding of the knife in order to ensure the accurate trimming of different materials
  • Grinder for sharpening the knife
  • Alternatively, a steel knife bar is possible

Foundation Plan

Driven roller conveyor

  • Driven roller conveyor in the area of the side guide
  • Secures a constant further transport of the block in the aligned position

Third/fourth cutting unit

  • Additional cutting unit for centre cut
  • Offers the possibility to simultaniously cut a maximum of 3 trimmed blocks from one long block at the same time

Motor-driven adjustment

  • Motor-driven adjustment of the trimming units
  • Most precise positioning of the cutting units by motor
  • Pre-selection of the position by a separated operator panel

Motor-driven grinding units

  • For an even finer grinding of the band knife

Stable side guide

  • Parallel alignment of the block to the cutting units upstream of the IS/BA
  • Allows the realisation of smallest trimming cuts
  • Optionally, this unit can be controlled by means of remote control in a central operator panel.

Steel knife bar

  • For achieving very small trimming cut thicknesses with long blocks we recommend the use of a steel knife bar
