Parameter control by tablet

Through Wi-Fi communication the equipment can be operated by tablet, cellular or notebook to control the variables. This allows freedom for the operator in any position, even when the machine is in confined environments.

Simplified substrate bonding system

The system developed for bonding the substrate in a loop is easy to use, with efficient results in several materials. The use of termo adhesive guarantees flexibility and resistance in the joint. In addition, a manual adjustment in the angle of the rubberized cylinder compensates possible misalignment.

Controled substrate tension

Automatic function keeps the substrate tension at the selected levels, avoiding tensioning losses caused by thermal expansion and accommodation of the plastic substrates.
