RotaDobe – your cutting machine becomes a mini cutting line

Do you run a business in the polyurethane industry and you are struggling to manage materials logistics and crosscuts on your foam blocks? Does all this result into low productivity for your company? There is only one solution, which is RotaDobe.

The RAM RotaDobe integration can be fitted on all our horizontal contour cutting machines – with a view to transforming them into mini cutting lines. Whether you choose an endless band-knife (e.g. our SLC EV), an oscillating blade (e.g. our SPL EV), or an abrasive wire contour cutter (e.g. our SFI EV), you will still get the opportunity to integrate this optional to your machine.

But what exactly does the RAM RotaDobe do?

It enables you to set up automatic cutting mode so as to manage the loading-unloading cycle as well as the entire processing of the foam block. In more details, thanks to the RotaDobe configuration, once the block in input has been loaded onto the machine:

    • it will automatically align and wait in the inlet of the machine, until the previous block has been completely processed. Isn’t it cool?
Thanks to the smart aligning function, indeed, you won’t need extra space outside the body of your machine to be able to align your blocks. Everything is done on board!
  • Afterwards, the foam block will slide forward towards an automatic rotating table (while the previous block shifts towards the outlet).
  • Lastly, while the first block has been unloaded in the outlet and the second one is being processed on the cutting table, a third block can be loaded in the inlet, to continue with the workflow.

In other words, it is a concatenated manufacturing process that, potentially, could repeat endlessly, provided that there is material in input.

Why is the rotating cutting table automatic in the RD configuration?

The RotaDobe system has been conceived to enhance productivity, therefore it is time- and effort-saving. An automatic rotating table entails that you can perform crosscuts without human intervention needed to move the block. A crosscut consists in two consequent cuts, on two different sides of the block, so as to obtain a 3D result (see picture below).

The RotaDobe’s evolution over time

  • In 2004, the first version of the RotaDobe system was designed. However, this model was still far different from the current one. Its working phases being identical notwithstanding, indeed, the workflow and working time were completely different. In more details: alignment, loading, cutting and unloading were four different phases in a row and none of them used to overlap.
  • In 2015, our technical team and engineers managed to launch a new, enhanced configuration. RotaDobe II was now able to align a second block in the inlet of the machine, while the first block was being processed, thus reducing time and increasing productivity.
  • However, the greatest success concerning the RotaDobe integration has arrived this year. RotaDobe III currently enables to manage three blocks at a time: when block no. 1 is resting in the outlet of the machine (parking area), block no. 2 is being processed, and block no. 3 is being aligned in the inlet of the machine. In other words, the cutting phase of block no. 1 overlaps with the aligning phase of block no. 2, and the unloading phase of block no. 1 overlaps with the loading of block no. 2. That’s why we talk about a mini cutting line!
