Glue Applicator Tips and Tricks
Does anybody have experience with a hopper system like this one? Is there a way to regulate how much glue this thing feeds? Is there a way to effectively cover the top so the glue does not get too thick between glue ups (3-4 hours)? How easy are these to clean? We use yellow Titebond glue. The literature says this is good for PVA type glue. Would a gravity hopper work okay for thicker aliphatic resin glues?

Put the whole spreader inside a plastic bag or inside a plastic container with a lid. I have been using clear plastic containers that you get at the grocery store with salads or cakes. It will hold for days just sitting on the bench. Also cut a notch in the lid so the handle sticks out.

We've got a Lamello brand glue pot, hose and nozzle system that works well. It can sit for a week with the applicator in the water and be ready in 10 seconds. A bit pricey.

How wide and thick are the lumber sticks being glued together?

I recently used that very glue applicator to glue up approximately 200 sq ft of veneer. I did 16 panels in 2 days using Titebond Type l Extend. It gives 15 minutes open time. I asked a version of your question two weeks ago.
First I made a simple snug lid for the top. Then when I was done with the application, which typically took about 2 minutes on a 2' x 8' panel, I put the hopper on its stand in a plastic container with approximately 3" of water, coming just below where the glue comes out of the hopper.
When I was ready to apply again, I rolled the wet roller on newspaper 6 times each on a dry area. The roller was dry and ready to use again. At the end of the day, I drained the hopper, which is not 100% by any means, and then immersed the entire assembly in about 5 inches of water.
The next morning I took the hose to the entire thing and got it 99% clean and started again. If you clean it thoroughly at the end of every day, it might take 15 minutes to get it perfect. There is a container especially made for this hopper somewhere out there. I have used it for Unibond 800, but I'm pretty sure you have to do a 100% clean up at the end of each session.

If you do a lot of gluing, you can spray it on, or if you have good mechanical abilities, you can make a curtain coater - we made one 40" wide, but that was to apply a water based glue. You may even want to look at different glues for your operation.
