|Spray Tow Retention|
|The application of aqueous dispersion adhesive (PVA) fed either by pressue pot or pump, on a filter making machine.|
|The Proportional Spray Tow Retention System is designed to apply a wide coverage of adhesive to the filter paper, anchoring the tow. Installed either as an additional component to the Kaymich GFH system or as a stand-alone system, the PST is suitable for a wide variety of filter makers and combiners.|
What does the system comprise?
• Applicator • Mounting bracket • HMI • Speed sensor/encoder • Control box including air regulators for spray air and adhesive air. • Adhesive pump Assembly • Adhesive tank
What is the minimum width pattern the system is able to produce?
We have successfully produced consistent patterns as narrow as 3mm. It may be possible to reduce this further subject to materials (adhesive and paper) and machine speed.
What is the diameter of the applicator orifice?
The applicator nozzle has an Ø0.8mm orifice.
What adhesive specification can be used?
Typically PVA adhesive between 500 – 1500 centipoise, solids content 20% - 50%. Adhesive specification is key to acheiving the desired results. HB Fullers IPACOLL LP2934B has recently been successfully used in extended tests.
Can the system be integrated into the maker controls?
No, not currently.
Can the PST system be used with multi segment filters?
