SOKO Electric Creasing Machine Perforating Paper Folding, 3-in-1 Automatic Cutting 18"(460mm) Width Perforator Paper Folding Machine for Tickets Documents Cards Photos Invitations

Bought this for a small business so we can crease our project documents, proferate our invoice bottoms, add proferations to our self-printed notebooks. Machine does all of this. It comes with 1 cutting wheel, (2) 2piece creasing wheels [you can make 4 creases in 1 pass if you are OK with the minimum unadjusted spacing or you can make 2 creases spaced however far apart you want], and 1 proferated cutting wheel. Everything was together out of the box and toom about 30 seconds to adjust. Everything adjusts with a basic Allen wrench they provide. I only do one sheet at a time. Directions are very poor - no pictures, really bad translation, and just not descriptive. The machine is really simple to figure out. Just DON'T stick your fingers near the opening as it is very deep. I only do 1-3 pages at a time, but it goes fast. I posted some images to show the wheels and the simple Allen wrench adjustments. You can configure the width and what combination you would like. It is really easy to just raise and lower blades/creases you don't need. Just be really careful with hands - I would never use this in a school/woth kids or with someone who does not pay attention.

The small gear on the shaft with the cutters & perf wheel had large burrs from drilling and tapping for the set screw, and the screw itself stuck up into the gear teeth. All this caused the drive belt to hop on every rotation, causing a loss of drive power. We disassembled the machine, removed the gear, sanded down the burrs, drilled the shaft deeper and sanded off the tip of the set screw so when reinstalled, it would go deep enough into the shaft so it would not stick up and interfere with the drive belt. That done, so far we haven't gotten the machine to perf in a straight line. We may have to make new paper guides.
