5-4 : Cross Folding

  • Cross-folding is to further perform double parallel fold or

letter fold on a sheet of paper folded already by single fold.

  • This is good for folding A3 size stock which is already

folded by double parallel fold but still will not fit into a

 Paper that can be used for cross folding varies according to

the conditions such as type of paper, paper size, paper

with lateral grain, paper with vertical grain, temperature

and humidity, printing conditions.

It may occur that lateral slanting is larger than normal

folding or the corner of the crease is folded inward, but this

is not caused by machine failure.

Press along the single folded line of the paper with fingers.

The amount of paper loaded should be less than normal (30 sheets or fewer).

Auxiliary paper guides should be placed away from built-in paper guides, and the roller should

hold down the single folded line by the first folding process.

  1. Load single-folded paper on the feed table and secure it with the built-in paper guides from both sides.
  2. Slightly loosen the right and left screws of the paper feed auxiliary roller, and set them to where both ends of

the paper are held down.

  1. Set the right and left auxiliary paper guides where the bearing at the edge will accommodate the previously

single folded paper edge.

As the holder of the paper feed auxiliary roller is made of resin, take care not to damage

holder by tightening the screws paper too tightly. 5-5 the : How to fold art paper/coated

5-5-2 : Pressure adjustment

[1] Set the paper feed pressure adjustment lever at “0”

[2] Set the separator pressure adjustment lever at “2”.

[3] Properly fan out the sheets of paper before loading

Fan out the sheets of paper, allowing

air to come in between the sheets.

Caution! In the case of printed art paper or coated paper, the degree of adhesion may be very strong, and paper feed errors are more likely to occur even after taking steps [2] and [3]. Therefore, be sure to fan out the sheets of paper sufficiently before setting the paper on the paper feed table.

Fan out the sheets of paper a few times both vertically and horizontally. The paper will then

be fed more smoothly.

If the volume of loaded paper is large, paper feed troubles are more likely to occur.

Both art paper and coated paper easily attract static electricity. If paper feed troubles

frequently occur, remove tables 1 and 2, and spray anti-static spray near the edge where

paper enters. It is recommended to spray frequently to remove static electricity.

MBM 508A Paper Folder User Manual, page 25
Text on page 25

< If double feed is frequently occur>

  • Referring to the illustration on page 22, properly fan out the sheets of paper again.
  • Ensure that the paper to be loaded on the paper feed table is no higher than 10 mm.
  • Change the position of the separator pressure adjustment lever to “3” from “2”.
  • The higher the setting of the separator pressure adjustment lever, the stronger the force of separating

the sheets of paper.

  • Lower the processing speed level by one.

Note:

It is recommended that above adjustment is done at middle folding speed of 3.

speed by one step at a time if necessary.

<If paper feed slip frequently occurs>

  • Change the setting of the paper feed pressure adjustment lever from to “1” from “0”
  • The higher the setting of the paper feed pressure adjustment lever, the stronger the force of feeding
  • Increase the folding speed level by one.

Note:

It is recommended that above adjustment is done at middle folding speed of 3.

speed by one step at a time if necessary.

5-6-1 : Slant adjustment

If the folding position is slanted because the paper is cut at a slant or for other reasons, it can be adjusted using the slant adjustment knob.

Turn the slant adjustment knob to the right direction 1, if the lower side of the folded paper slants to the right. Turn the knob to the left to the direction 2 if the lower side slants to the left. (The basic position of the knob is the center where the pin is aligned with the slot.)

Caution !

Check if there is any space between the paper

guides and the paper.

In cases other than single fold, put the folded paper at Table 1 face down to make a slant ejection adjustment. If paper is reset at the paper feed table, start slant adjustment over again. After specific job is completed, return the slant adjustment knob to its basic position, i.e., center in the slot.
