Villars, Hotmelt Powder Scattering and Laminating Machine, 1993, 2200mm, 158kW

Villars, Hotmelt Powder Scattering and Laminating Machine, 1993, 2200mm, 158kW

Description

  1. Overview
    1. Laminating line with accumulator, winder, controlling system, and superstructure for second substrate supply
    2. Make: Villars (CH) actually Santex
    3. Year: 1993
    4. Working width: 2200 mm (nominal width 2 m 10)
    5. Voltage: 3 x 380 (400) V
    6. Total power: 158 kW
    7. Recommended max. speed 10 m but 15 m is possible
  2. Laminating Line Configuration
    1. Original configuration: input unit (with possibility to hang in rollers by means of e.g. flat bearings), powder spreader, infrared preheating zone and double band laminating press (heating through IR)
    2. Later extension (1997): 2nd infrared zone with cold water cooled calendar
    3. At the back equipped with selvedge cutting system with adjustable infrared follow up system
    4. Strength of infrared can be adjusted so that e.g. the upper substrate can be ‘neglected’
    5. Known problems: infrared preheating zone: 2 IR strips broken; 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 to 170 °C and even more, but then at very low speed
  3. Accumulator With Winder And Controlling System
    1. Make: Matthijs (electrical part by Electro Vandewelde)
    2. Year: 1999
    3. Operating voltage: 3 x 380 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)
  4. Superstructure For Supply Second Substrate
    1. Make: Menzel
    2. Year: 2000
    3. Operating voltage: 3 x 380 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; it is even possible to go to a +/- tensionless situation
    10. The line is mounted on a self-made platform equipped with a simple unwinding unit
    11. Known problem: pressure roller to avoid that the substrate “slides” over the brake roller is worn out, but is in praxis not needed; motor of the pre-guidance is broken (see above)
  5. 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
