Fan the Forms, then Adjust if Needed
The simplest, most non-technical method of making sure the forms don’t stick together and “Multi-Feed” is to fan them like you’re thumbing through a deck of cards on the edge prior to placing them in the feeder. However, if it’s a little more involved, a simple adjustment of the gap feed is all that’s needed to control the double feeding and you’ll be back on your way to smooth operations in no time.
Sometimes, this is referred to as “Multi-Feed“, and is easily fixable by adjusting the feed gap. Read through the full post first, then go back over it one more time before you dive in.
Three steps to tighten the “Feed Gap”
- Grab the Allen Wrench that came with your folder sealer equipment. (If you’re not familiar with an Allen Wrench, it’s the red-handled T-Bar that hopefully you still have with the instruction manual.)
- Then, find the blue belt(s). Directly above the blue belt(s), there’s a cover with two black screws and right in the middle is a set screw.
- That’s where you adjust the feed gap. To tighten, insert the Allen Wrench and turn counter clockwise. To loosen, turn clockwise.
Looking right above the blue belt(s), you’ll see a silver drum with clear plastic “O” rings around it. As you adjust the gap (tighten or loosen), you’ll notice the drum move up or down (depending upon whether you’re tightening or loosening) off of the blue belt(s). You want the drum with the “O” rings to barely touch the blue belt(s).
Testing the adjustment - Once you’ve adjusted the feed gap, you need to test a form by manually inserting and pulling it out to “test the drag”. To do this, simply place one form down and gently push it toward the roller until it won’t go any further. Now, pull the form out and gauge the “drag” on the form as you pull it out. If there is “little to no drag,” then you need to tighten the gap more.
Once you’ve adjusted it, do a test run through the machine with several forms. If it still “Multi-Feeds“, then it needs to be tightened more. If it doesn’t feed any forms through at all, and you notice the blue belt(s) aren’t moving, then you have the gap set too tight and it needs to be loosened a bit.
Until you get the forms running through one at a time, repeat the above tightening and/or loosening steps. Hopefully this makes complete sense and it’s a snap to adjust. Should you need further explanation on adjusting the feed gap, review the instruction manual that came with your equipment. But, I’m keeping my fingers crossed we fixed it easily.
