BSV-ET

Splitting of glued long blocks (60 or 120 m)

BSV-ET long splitting machine

Most economic production of foil ware with a max. speed of 350 m/min: with foil thicknesses from 1 mm to 50 mm it is possible to wind a max. roller diameter of 1.5 to 2.4 m, depending on the corresponding machine version

  • The long block to be split is continuously fed to the cutting portal by an endless transport system which is located in two reinforced semi-circular towers equipped with belt systems.
  • Lowering of the cutting unit by the required foil thickness after each block cycle
  • For the reason of length compensation, the tower after the cutting unit can be moved by motor
  • A motor-driven side guide installed upstream of the cutting unit for an accurate block guiding and for bonding the block. The current position of the side guide is displayed on the operator panel.
  • Highest possible level of automation by adjusting the cutting angle and the position of the pressure roller by motor - these parameters can be individually stored for each job.
  • Maximum cutting velocity of 350 m/min
  • Maximum block weight 15 t with a block length of 60 m
  • Continuous, constant cutting result due to a programmable, all-automatic movement of the cutting angle adjustment, pressure roller position and knife bar in dependence on the foam quality
  • Adjustable knife motor for the individual and optimal adjustment of the knife speed to the material or to the cutting speed, respectively
  • The machine control is an efficient PLC by Siemens with a high operating convenience
  • Storage of numerous cutting programmes and machines settings directly at the control panel
  • Adjustable knife motor for the individual and optimal adjustment of the knife speed to the material or to the cutting speed, respectively
  • Continuous, high-quality grinding of the knife by a high-precision grinding unit with pneumatic advance of the cup wheels
  • Grinding cycles and grinding duration of the knife can be pre-programmed.
  • Equipment of the main transport conveyor with a vacuum unit for a better fixation of the piece to be cut in the lower block area.
  • In order to compensate individual block running characteristics and material qualities, the transport belts are driven by 8 reinforced belt drives.

Foundation Plan

Third tower

  • As a special version, the BSV-ET can also be equipped with a third tower
  • By this, two different lengths of glued blocks can be converted in the machine

Pressure roller

  • Motor-driven pressure roller
  • Necessary for the cutting of thin foils (1-5 mm) made from lightweight foam qualities (1-5 mm)

Motor-driven winding unit

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

  • Version B: The winding unit consists of a belt system mounted on a moveable lifting platform. During the splitting operation, this automatically follows the cutting unit as the block height decreases. The operator stands on the lifting platform to ensure easy operation of the winding unit

Troughed belt conveyor

  • The troughed conveyor is directly placed downstream of the winding unit
  • Allows an easy removing of the completely wound foam roll from the machine to one side

Cross cutter

  • Circular knife cross cutter for economically cutting off the foils after they have reached the preset foil length

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-EC

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
