TROUBLE SHOOTING IN THE PRINT INDUSTRY

Bubble & folding tolerances (folding pins)

Bubble & folding tolerances (folding pins)

What causes folding tolerances?
With folding pins in conventional design, it often happens that the inner ribbon tends to form bubble (see arrow), which can result in folding tolerances.
 

How can the folding tolerances be avoided?

The improved design with the tapered needle applies more tension to the ribbons and can thus avoid or completely eliminate this problem and improve the durability of the folding pin.
