Villars-Santex, Hotmelt Powder Scattering and Laminating Machine, 1993, 2100mm, 158kW

Description

  1. Overview
    1. Laminating line
    2. Manufacturer: Villars (CH) actually Santex
    3. Year of construction: 1993
    4. Working width: 2200 mm (nominal width 2100 mm)
    5. Operating voltage: 3x380(400) V
    6. Total power: 158 kW
    7. Recommended max. speed 10 m but 15 m is possible
  2. Original Configuration
    1. Input unit (with possibility to hang in rollers by means of e.g. flat bearings)
    2. Powder spreader
    3. Infrared preheating zone
    4. Double band laminating press (heating through IR)
  3. Later Extension (1997)
    1. 2nd infrared zone with cold water cooled calendar
  4. Additional Features
    1. At the back equipped with selvedge cutting system with adjustable infrared follow up system
    2. Strength of infrared can be adjusted so that e.g. the upper substrate can be ‘neglected’
  5. Known Problems
    1. Infrared preheating zone: 2 IR strips broken
    2. Certain parts IR zones (mostly exterior zones) of the double band laminating press do not longer function, but second part of the machine can still be heated till 160 à 170°C and even more, but then at very low speed
  6. Accumulator With Winder And Controlling System
    1. Manufacturer: Matthijs (electrical part by Electro Vandevelde)
    2. Year of construction: 1999
    3. Operating voltage: 3x380 V
    4. Capacity accumulator: +/- 50 m
    5. Unit functions independently from laminating machine and speed varies from 0 till 50 m (speed of winding up unit = speed laminating machine when accumulator is empty)
  7. Superstructure For Supply Second Substrate
    1. Manufacturer: Menzel
    2. Year of construction: 2000
    3. Operating voltage: 3x380 V
    4. Functions independently from the laminating machine
    5. Speed regulation based on a 0-10 V (=0-15 m) exit signal of the laminating machine
    6. Manual right-left guidance of the substrate
    7. A second automatic pre-guidance is foreseen, but the motor does no longer function and it is in practice not required because the rolls are always winded straight
    8. A measuring roller is included to measure the tension of the substrate
    9. This measuring roller directs the motor speed so that the adjusting of the tension stays steady
    10. It is even possible to go to a +/- tensionless situation
    11. The line is mounted on a self-made platform equipped with a simple unwinding unit
  8. Known Problem
    1. Pressure roller to avoid that the substrate “slides” over the brake roller is worn out, but is in praxis not needed
    2. Motor of the pre-guidance is broken (see above)
  9. Miscellaneous
    1. Self-build entry J-box with simple roll measurement
    2. Separate J-box for unwinding from docks, so that can be laminated in the pole direction
    3. Sewing machine Merrow to make flat seams on fine/thin fabrics
    4. Selvedge cutters are mounted on a system so that the fabric can be levelled easily, eventually can be winded on docks
    5. Including 2 docks of 2 m 30 of which 1 with flap bearings
  10. Condition And
    1. Can be inspected but not in production
    2. Dismantled and stored at the factory in Europe
