Key Features of the Patch applicator
Multi-Web Compatibility
Capable of working with multiple supplementary webs for double-width or wider production.
Register Control for Pre-Printed Webs
Achieve perfect alignment when using pre-printed supplementary materials.
Flexible Patch Lengths
Freely define the patch length to match your production needs and combine it with varying repeats on the carrier web.
Precise Cutting and Placement
The unit includes an infeed for supplementary webs, a knife cylinder for cutting, and a vacuum-supported anvil cylinder to position patches accurately on the carrier web.
Integrated Silicone Liner Rewind
Ideal for laminates, with the silicone liner rewound directly before the cut-off process.
How It Works
The applicator comprises four primary elements: an infeed system, a rubber counter-pressure cylinder, a knife cylinder, and an anvil/vacuum cylinder.
- The knife and vacuum cylinder operate in synchronization with the main web speed, ensuring flawless cutting and placement of patches.
- The infeed system controls the patch material’s speed, dictated by the desired patch length, which is easily set using a touch screen interface.
- For pre-printed materials, an electronic gear combined with register control ensures patches are cut and applied in perfect alignment with the print on the supplementary web.
Depending on the application, the unit offers two infeed systems: a traditional cylinder infeed or a vacuum band infeed system, the latter being particularly suited for applying hot melt glue to the supplementary web.
