Apparatus for granulating strand materials including a stationary knife, a rotatable knife, and a drawing-in device. Part of the housing is pivotable to enable the drawing-in device to be easily removed for maintenance. An oblong hole on the housing is used to locate the drawing-in device.

Granulating device for strand materials

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.

The invention relates to a granulation apparatus for strand material having pull-in apparatus for gripping the strand material and transporting it to a counter knife, a knife roll cooperating with the counter knife for cutting the strand material into granulate, and a housing accomodating the pull-in apparatus, the counter knife and the knife roll, wherein a motor driving the knife roll and the pull-in apparatus is arranged beside the housing and is connected by means of a drive axle to the rotating components contained in the housing, and wherein the motor and the housing are mounted on a common support. The mounting assembly includes two mounting devices which, in a projection onto the support, are arranged in the region of the two side portions of the housing which are beside said drive axle such that, due to the torque acting on the housing, the one mounting device (tension holding device) receives a tensile force away from the support and the other mounting device (the pressure holding device) receives a force of pressure against the support. The tension holding device, due to its hook-like formation, releasably holds the housing onto the support, and the pressure holding device is formed as a catch, thus preventing movement of the housing away from the tension holding device.
