Abstract
The invention relates to a granulating device for strand materials comprising a pull-in device for feeding the strand material, conducted through an inlet shaft, and transporting it to a knife roll for cutting up the strand material into granulate, said pull-in device having a pull-in roll, and a counter-roll, of which rolls at least one is driveable and both form a inter-roll gap for pulling-in the strand material. A proximity-type switching element is disposed in the region of the inlet shaft, particularly in front of the entrance thereof, said proximity-type switching element raising, when actuated, the setting of the inter-roll gap and increasing the inter-roll gap to such a width that the further pulling-in of the strand material is abruptly stopped.
