Cool-Vac Doublefacer

The Cool-Vac Doublefacer from BW Papersystems eliminates crush and web weave, while improving board quality. Learn more about our corrugating machinery.
Doublefacer MarquipWardUnited’s Cool-Vac Doublefacer design minimizes the length of the pulling section and allows the heating length to be easily configured for given space and product mix requirements. Corrugator Components: Cool-Vac Doublefacer Belts Hot Plates on the CoolVac Doublefacer

Machine Configurations

Roller System (RS) Heavy-Duty Doublefacer

The hold-down system is comprised of precise liquid-filled weight rolls.

Roller System benefits:

  • Provides even distribution of belt pressure for optimum heat transfer and excellent bonding.
  • The rolls do not warp. This eliminates board quality defects, even after a stop.
  • Weight rolls produce less drag on the belt, resulting in energy savings.
  • There is no need to eliminate load on the belt edges as a paper width changes. This ensures consistently good bonding across the entire web no matter how narrow the web is.

Heat Press (HP) Sliding Shoe System

The Heat Press system is a unique shoe design that is stiff in the cross-machine direction. If only a small amount of web is under the shoe, the shoe will not tilt down.

Heat Press benefits:

  • Provides excellent bonding while eliminating board crush.
  • Ensures superior bond at the board edges regardless of the web width.
  • Eliminates the need for “outside shoe offloading systems” and eliminates the belt wear associated with typical shoe systems that do not offload.
  • Relatively simple system with few mechanical parts.
  • Sections of hold-down can be lifted or lowered by selecting any one of a series of computer-controlled zone hold-down section versus speed curves to accommodate various board grades.

Product Detail

  • Vacuum Traction Section eliminates the possibility of board crush in the traction section. Superior traction is provided without the use of a nip to pull the board. Board caliper and stiffness are not compromised, and the highest possible caliper is preserved throughout the entire corrugating process.
  • Vacuum Traction Section removes steam from the flutes, curing the board as it exits the doublefacer.
  • Board that is closer to plant equilibrium can be converted at higher speed or shipped immediately to fulfill customer delivery demands.
  • Gun-drilled steel hot plates virtually eliminate cupping and deflection normally experienced with conventional Doublefacers.
  • Modular design allows hot plate length to be optimized for the board grades and required speeds.
  • Any combination of heating sections or individual hot plates can be customer designed and built.
