Hot foil stamping machines RF 82 and RF 90
The hot foil stamping machine in round-flat-technology for highest quality requirements
The hot foil stamping machine in round-flat-technology offers you clear benefits: It gives you more stamping quality and more efficiency by innovative foil feed, more performance and efficiency due to newly developed foil reel bins, more accuracy due to height-adjustable form bed and more productivity through non-tool quick changeover feature of mounting plate. Through the precise fitting of the mounting plate, re-adjusting of the stamping dies is redundant.
More stamping quality and more operating efficiency due to new foil feed
The stamping foils are conveyed through spm steuer’s RF 82 and RF 90 with new methods: Directly after the nip, the foil is led off sharply upwards. This has two benefits:
Higher quality: Due to the fact that after the application, the foil webs are led off sharply upwards, they are not permanently exposed to the heat of the stamping dies. Therefore, they are less pre-activated. Consequently, when using specific foil qualities, an improvement of the stamping result and an increase in performance is achieved.
Easy handling: The foil feed provides optimum access to the stamping form, which makes it possible to re-adjust the stamping dies without any interference by the foil. For easy feed of a new foil web, the machine can be driven to a specific web feed position.
More performance and efficiency due to newly developed foil reel bins
With their newly designed foil reel bins, the RF 82 and RF 90 provide various benefits. Two of them are:
Full speed through brake: Sounds paradox, but when taking a closer look, it makes sense. The newly developed foil brake allows adjustment of the foil web tension during machine operation. This makes machine stops for re-adjusting the tension of the foil webs mostly redundant.
Unrestricted utilization of foil reel bins: Foil rolls with a diameter of up to 125 mm with the RF 82 and 150 mm with the RF 90 can be used without restrictions at any position of the foil reel bin. The widths are 800 mm with the RF 82 and 880 mm with the RF 90. The individual rolls are separated from one another by separation discs of only 2 mm thickness.
Pressure adjustment virtually as quick as a wink through height-adjustable form bed
With many other stamping machines using the cylinder principle, stamping is quite an affair. A miscalculation means reajusting, re-fitting and re-setting quite a few things. The RF 82 and RF 90 stick to the base, because they shift the adjustment of the nip to the form bed. The height-adjustable form bed means saving time and at the same time continuous quality:
Extreme reduction of setup time: A once fixed and set cylinder packing does not have to be change when requiring more of less pressure. The nip is adjusted to the pressure requirements through simple, fast and precise lifting or lowering of the form bed.
Cutting edge precision: Because the packing and thus the cylinder diameter remains unchanged when adjusting the pressure, there are no changes in print lengths and register. The 1/100 scale of the display allows optimum pressure adjustment.
Higher productivity due to non-tool quick changeover feature of mounting plate
The stamping dies of the RF 82 and RF 90 are mounted on a mounting plate, which is fixed precisely in the machine without using any tools. This also has two important benefits:
Less setup time: You can easily pull out the mounting plate. No tools are required to take out or switch the mounting plate. Fixing and unlocking the tool mounting plate is easily done via quick clamps.
Higher accuracy: Through the precise fitting of the mounting plate, possible registration inaccuracies are prevented. In most cases, re-adjusting of the stamping dies is redundant.
