Last week, I used this space to brag on our Super Air Knives, and how they solve a common problem in bottling applications: label adhesion. This week, I have another opportunity to brag on the Super Air Knife. AND it’s another solution to a labeling problem.
Self-adhesive labels are commonly applied to goods are they travel on high speed conveyors. If they’re going onto a flat, smooth surface (like a box,) it’s pretty easy…they come right off a timed roller with a wheel that presses them in place. This can even work with round containers (like drums, jars, or bottles) by putting an idler on the wheel to take up the slack as it rolls over the rounded surface.
Sometimes, the label needs to go around the corner of a box. This requires the roller to turn that corner. Or two rollers to pull the old “one-two” on the label. Either way, that’s going to slow down the speed at which the conveyor can be run. And time is money.
Enter the Super Air Knife…mount it so it’s blowing at the corner. The laminar, high velocity air flow will then press the label in place on each adjacent surface.
Another benefit: when supplied with clean, dry air, the Super Air Knife will run darn near indefinitely, maintenance-free. Those rollers get dirty, and the bearings will fail eventually. Same with the idlers, and they’ll need adjusted from time to time.
