The machine works with a flat printing process with stamping foils, which requires a short standstill during the printing process. Likewise, the print quality is excellent on the finest silk, wool and cotton fabrics right down to the thickest felt.
Due to the varying degrees of fabric thickness, the contact pressure can be easily adjusted. The standard version of the machine is designed for operation from roll to roll. Alternatively, the machine can also operate from bulk batches, from stack to stack, or combinations thereof.
The fabric is fed into the machine via a driven feed roller, from a small roll, stack or large batch. The fabric is then brought to a short standstill by two guide rollers swinging in a certain rhythm, and the fabric is then fed directly to the reel via the second feed roller. During the short standstill, however, the unwind, feed and winding rollers continue to run continuously without any fabric distortion, which ensures that the machine runs absolutely smoothly.
The printing apparatus operates with a flat printing set. This may be composed of standard letterpress types and LOGO. It is not necessary to engrave special clichés, as is the case with rotary printing. This allows the machine greater "freedom of movement" and ensures that all customer requirements can be met.
The maximum font length is 22 cm ("85⁄8") and the maximum height is 2 cm ("25⁄32").
During foil printing, the galley is electrically heated. Since the working temperature is different for different types of foil, as well as for different fabric qualities, it can be optimally adjusted by a control thermostat. A thermometer is built in for monitoring purposes.
The feed of the printing foil occurs automatically and can be adjusted according to the font height. The foil wear is extremely low in contrast to the rotary printing process. All parts can be removed in a few simple steps without the need for tools.
A mechanical device also makes it possible to stamp at pressure intervals of 1, 2 or 3 meters (or yard). For an extra charge, printing can be carried out in meters and yards.
The print head is automatically guided along the selvedge, controlled by an optical sensor, so that printing can be directed precisely onto the selvedge.
In the rotary printing process, a narrow foil strip is used according to the font height + safety distance. With our method, the distance between two prints on the printing foil is only 1 mm.
The foil wear is approx. 70% compared to the 25% with the MAAG flat printing process. The amount of printing foil used is approx. 150% higher in comparison with the cost-saving MAAG system.
