Glue adhesive to nylon using dipping.. Any design tips?

Glue adhesive to nylon using dipping.. Any design tips?


My company requires me to design a mechanism to dip a chord of nylon (about 1 m long) into a container filled with glue. The glue has similar viscoscity as oil although we have not finalised the glue properties yet. It is either a thermal cured or UV cured glue.

The proposed design is:

Dip the nylon chord vertically into and out of a sealed container with the help of one or two rollers. After the chord is out of the container, either a thermal or UV source will be there to cure it. I am not an expert in dipping mechanism so I need your help.

The chord is probably around 0.4 mm to 0.8 mm thick and we need a glue thickness of around 200 microns on the nylon.

1) May I know what are some standard designs available in the industry in glue coating?

2) How do I control the thickness of glue? And, is there some standard equipment that can measure the glue thickness, give feedbacks and adjust the thickness accordingly? I need the glue coating on the chord to be as uniform as possible.
3) Where or How should I design the rollers? At what distance apart and how big should the rollers be?

4) At what optimal speed is best for pulling the chord?

I am thinking of setting up some simple experiment to test the various parameters.. But I'll like to hear expert's opinions first, esp on the roller design...

If there's any company whom you can recommend me, feel free to...

Your help is kindly appreciated.
