Granulators for Thermoforming Operations are either beside-the-press or under-the-press.  Under-the-press machines sit below the thermoforming press to immediately recycle the plastic skeletal waste. They grind plastic as part of the continuous thermoforming line.  Beside-the-press granulators are separate from the process.  These can be used to feed plastic skeletal remains or entire sheets of bad product.  Both types are usually fitted with speed adjusted pull rolls to either synchronize with the press or adjust for the product.

An example of a beside-the-press granulator can be found here:
