VARIOUS APPLICATION SYSTEMS
(coating, finishing/ impregnation)

 

Coating: Substances (paste) on top of the material only
 

One sided (low add-on) / both sides (event.different subst.)
 

Only a rough idea of possibilities is given. Many others are on the market for special requests. The delivery scope of TIMATEC you find in the various and leaflets
competitors.
 


Kiss coating system:

 

 

Single roll system
Dip roller has tangential contact with material.
For low viscosity fluids only
 

 

Reverse roll coater:

 

 

2 roll system, application roller
rotates opposite to material direction. Dosing between roller 1 and 2. Appl. Roller with contact to the surface of material
 

Rotary screen coating:

 

 

Screen coating with paste or foam
Screen to screen –same, but
Both sides at a time
Special squeegee needed for foam

Knife on air:

 

 

For low amounts
Amount of appl. Depends on material surface, viscosity of paste, and the working geometrics (knife,angle…)
Common technique
 

Knife over roll:

 

 

Appl. depends on the distance between surface of the roller and knife edge (- thickness of material, very precise backup roller and knife are needed  (cost)
Common technique

 

Rubber conveyor coating:

 

 

Similar effect as the Knife on air coating, but with rubber backup conveyor support for better evenness of application
 

Double face coating:

 

 

Both sides at the same time.
Dip- or spread paste supply,
Two knifes as knife on air
 

 

Foulard / Mangle:

 

 

Dip/squeeze system
Widely used for impregnation purposes

 

Padder:

 

 

Bottom roller dips into the pad (fluid)
Top roller presses-in. Appl one-sided or with full penetration.
The Mangle also can be used as Padder

Spray system:

 

 

Several spray units accross the width, eventually oscillating or revolving

Rotary screen PASTE DOT coating:

For Interlinings and lamination
Waterbased hotmelt preparation
Various dot-arrangements are used

Powder coating:

 

 

Tank above a engraved roller, Rotating brush for Application.
Hot air melting oven needed
