Key Benefits

  • Designed for reliable automatic application of three component PUR adhesive
  • Applies adhesive onto two surfaces of sandwich panels
  • Upper applicator has automatic stepless vertical adjustment up to 300 mm
  • Reciprocating spreaders create a diamond pattern for excellent surface coverage
  • Very accurate coat weight control through flow controller and gear flow meters
  • Application width can be adjusted stepless from 500 mm to 1200 mm during operation
  • Integrated online automatic cleaning system for spreaders and mixers
  • Common PLC and HMI based control panel for machine functions, alarms and maintenance

System Components

  • Two adhesive spreaders each on their support or on a common frame
  • Servo drive, cable chain, mixer unit and spreaders
  • Six metering units with variable mixing ratio
  • Four units for the base pumps and two units for the curing agent pumps
  • PLC/servo based control system with graphic HMI operator panel
  • IBC stands with tilt mechanism and containment sump for collection of spillage
  • Transfer pumps for base and curing agent
  • Three accumulator tanks, one for each component
  • Automatic online cleaning system with diaphragm pump, purge and cleaning trays

Operational Highlights

  • Upper applicator applies adhesive directly onto the core material
  • Lower applicator applies adhesive directly onto the lower facing
  • Each applicator has an adhesive mixing unit containing two static mixers
  • Flow controller compares adhesive volume per second with set point value to adjust pump output
  • All pumps are electrically driven
  • Cleaning cycle blows out mixed adhesive, flushes the system and returns the spreader ready for bonding
  • Control panel provides alarms for routine maintenance, pump system errors, mixing ratio and coat weight
