Patented folding system<br />

The DigiFold dispenses entirely with buckle plates or<br />

conventional knives, using an electronically controlled<br />

“flying knife” contoured around extra large diameter<br />

rollers.<br />

The speed is mathing the dem<strong>and</strong>s of damageable<br />

digital prints. The DigiFold uses a dynamic sheet deflector<br />

that only touches the leading edge of the sheet. This<br />

reduces the risk of scratching or marking.<br />

Materials <strong>and</strong> applications<br />

• Difficult digital stock<br />

• Varnished print<br />

• Art paper<br />

• Coated or laminated material<br />

• Covers (stapled or glued)<br />

• Cardboard<br />

• Substrate with wrong grain direction<br />

• Thick paper<br />

• Menus<br />

• Greeting cards<br />

An extensive program sets the creasing<br />

<strong>and</strong> folding automatically<br />

Flexible <strong>and</strong> user-friendly<br />

For st<strong>and</strong>ard configurations, the DigiFold works in an<br />

automatic mode. Once the required fold <strong>and</strong> sheet<br />

length have been selected, an extensive program<br />

automatically sets the creasing <strong>and</strong> folding positions.<br />

An individual operation is employed when extra creases<br />

are needed or difficult configurations have to be programmed.<br />

In this mode the operator enters the creasing<br />

<strong>and</strong> folding positions manually via the joy stick.<br />

Proven creasing technology<br />

To avoid cracking of the substrate, the DigiFold works<br />

with a technique by which the fibres are embossed <strong>and</strong><br />

weakened. The creasing mechanism consists of a male<br />

creasing rule <strong>and</strong> a female matrix which get pressed<br />

together to perform an exact <strong>and</strong> crack-free crease.<br />
