Folding machines

A folding machine is a device used primarily to fold printed sheets in order to achieve a smaller format of a product with consecutively numbered pages. An example for such a product is a classic saddle stitched brochure.

There are two main folding principles – buckle folding and knife folding, latter mentioned normally combining both folding principles in one machine.

 

Knife folders hit the paper with a blunt .There are two main folding principles – buckle folding and knife folding, latter mentioned normally combines both folding principles in one machine.


Buckle folders feed paper until it hits an obstacle and reacts by buckling. Then the paper is transported between high friction rollers which squeeze the material and actually perform the fold. Finally rollers supported by a spring press the front edge of the paper into a so called pocket.
Knife between two rollers, just strong enough to crease the paper along the required line.
Paper folders can be equipped with two kinds of paper feeders:

  • Round-pile feeder – paper is fed non-stop: for high volumes
  • Pallet feeder (pile feeder) –for medium volumes
  • Flat-pile feeders (pile feeder) – for low volumes and small formats

Additional optional attachments for paper folders allow enhanced functions such as gluing, cutting, perforating and creasing.
Furthermore there are different options for delivering the folded product.
The conventional stream delivery delivers the folded paper on a belt and is gathered by the operator by hand for further usage. Vertical press deliveries deliver the folded paper in pressed stacks and are normally used for economic processing of larger volumes.
