As a former tool and die maker, this has to be my all-time favorite project.
99% of our work is small decals that measure 4" x 8" and smaller. Due to our process, and the special way we weed them, we have to cut them apart before applying the transfer tape.
Late last winter, I got tendonitis in my elbow and could no longer squeegee down the transfer tape...especially when a job calls for 1,000+ decals.
The photos below show a 4" roll of transfer tape in the machine. I lay the decals face down on the transfer tape (which is sticky side up), give the handle a quick crank, and the serrated cutting blade allows me to tear them off like Scotch tape. It's so fast that I'm now able to get my masking done in approx. 1/10th the time it used to take, and my elbow is much happier.
With waterjet cutting and tooling, I have approx. $400 into it but it paid for itself on the first job with the time we saved.
