WATER
SPRAY WARP CONTROLLER ASAI 2000
The warp is traditionally very annoying for the corrugator. It has
as consequences a lot of wastes and a loss of productivity for postprinting and die
cutting process. The principle, band humidification, in application with success on about
one hundred machines throughout the world, remains the same. Each ramp is composed of 10
spraying heads which can independently spray the required amount of water over a 250 mm
strip.
ASAĻ 2000 innovations
Based on the paper criteria, the amount of water sprayed is actually
proportional to the speed of the corrugator:

|
very accurate potentiometers, |

|
Atomizer spraying heads which enable a constant humidification cone,
independant from the water flow rate and homogeneous over the 250 mm strip, and which
cannot be blocked. |
Easy to install, to operate and to maintain.
Functioning
It cannot be more simple. When corrugator speed is stable, the
operator makes the drawing of the warp on the control pannel. Spraying heads work
immediately. The board is made flat. |

Control pannel example. |
If corrugator speed changes, the flow rate of each spraying head
will change in proportion.
Usual location of the ramp is : |

|
1 ramp operated on the upper single facer web, |

|
1 ramp operated on the double facer line. |
The Warp Control ASAI 2000 is composed of one or two spraying ramp
installed at the double backer :

|
1 spraying ramp operates on Single Face board. It allows the control of
reverse warp. |

|
1 supplementary ramp can operate on the outside liner and allows the control
of either "U" type warp and "S" type warp. |
