BSV-R

Low-cost long block splitting machine for the production of foils from bonded long blocks (20 or 30.5 m) with mid-sized capacity requirements

BSV-R long splitting machine

With foil thicknesses of 1 mm to 50 mm it is possible to wind a max. roller diameter of 1.5 m with both versions

  • The long block to be split is continuously fed to the cutting portal by an endless transport system equipped with rollers which is located in two reinforced semi-circular towers.
  • Lowering of the cutting unit by the required foil thickness after each block circulation
  • The long block to be split is continuously fed to the cutting portal by an endless transport system equipped with rollers which is located in two reinforced semi-circular towers.
  • Standard non-driven, manually adjustable pressure roller to achieve optimal cutting tolerances
  • Maximum cutting speed of 100 m/min in all versions and for all block lengths
  • Maximum total block weight of 2 t with the 20 m version and 3 t with the 30 m version
  • Max. block height of 600 mm with 20 m and 1 000 mm with 30.5 m
  • The swivelling cutting unit ensures the ideal adaption of the cutting angle to the respective material qualites or splitting thicknesses
  • Achievement of optimal cutting tolerances
  • Standard non-driven, manually adjustable pressure roller to achieve optimal cutting tolerances
  • Winding with high edge accuracy by means of winding units with two winding rollers and supporting spindles (max. winding diameter up to 1 500 mm)
  • The BSV-R can be combined with an IS-BA trimming unit inside the machine and a stationary ABLG II/ABLG IIs cutting-off machine upstream the BSV-R machine. By this, it is possible to level the block at its head side and end side by means of the cutting-off

Key Facts

Application

Automotive industry, mattress industry, footwear industry, apparel industry, packaging industrySplitting

Material

Polyether and polyester soft foams with various densities and strain hardnesses. Precondition: the flexible PUR soft foam used in the looper must be able to adapt to the radii of the deflection station without any difficulties

Cutting Tool

Precision-ground circulating ground knife (80 mm wide, 0.6 mm thick)

Foundation Plan

Motor-driven pressure roller

  • Necessary for the cutting of thin foils (1 - 5 mm) made from lightweight foam qualities
  • Adjustment of the knife bar by motor
  • Automatic readjustment of the knife bar with a worn-down knife this guarantees a constant cutting quality

Vacuum

  • Main transport conveyor with vacuum
  • For fixing/stabilizing the block
  • The additional fixation of the block directly in the cutting area of the knife prevents a lifting of the block with decreasing block height. By this, even foam qualities which are particularly difficult to process can be completely converted.

Querschneider

  • Dient dem rationellen Durchschneiden der Folien nach Erreichen der voreingestellten Folienlänge

Third tower

  • As a special version, the BSV can also be equipped with a third tower
  • By this, two different lengths of glued blocks can be converted, e. g. 30,5 m and 60 m

Moto-driven winding unit

  • Winding unit with 2 driven winding rollers; height adjustment effected using supporting spindles

Reverse mode

  • Reverse mode in connection with the second feeding bridge
  • For cutting long and short blocks made from materials which cannot be converted by a looper
  • By this function, a long block which cannot or shall not be glued can be converted to roll ware
  • Particularly for the cutting of heavy visco foams or similar materials

Cutting-off machine

  • ABLG II for a straight and angular trimming of the head pieces before the long block is glued
  • ABLG II S for a straight and angular trimming of the head pieces before the long block is glued. The cutting angle of the ABLG II S can be adjusted between 45 and 90 degrees. The angular cut of the ABLG II S guarantees a larger adherend particularly with foams which a difficult to convert
  • The set-up of the ABLG II and the ABLG II S is before the BSV

IS-BA

  • For an accurate lateral trimming of the long block
  • Adjustment of the cutting units either by motor or manually by hand wheel
  • Can be equipped with either a binding or a knife bar

ROK

  • ROK Roll compression system for compressing and packaging polyurethane foam in roll form
  • Compression and packaging of foam rolls for economic and space-saving storage and transport
  • Reduction of the foam roll volume of up to 900 mm depending on foam type and machine specification
  • For roll widths of 2 200 mm or 2 500 mm
  • For roll diameters from 400-2 000 mm or 2 500 mm
  • Belt speed of 20 m/min
  • Up to 5 freely parameterizable compression and packaging programmes enable to an optimum coordination of the processes referred to different foam types
  • Packaging foil is welded automatically when the number of entered wrap layers is finished
