Device to collect and convey plastic strands, issuing from nozzles, on a discharge plate, over which cooling water flows, with a device to indicate the undisturbed passage of the plastic strands over the discharge plate or their accumulation on the discharge plate. At least one temperature-dependent electric resistor, which triggers a signal by way of a threshold value switch when the specified temperature is exceeded, is attached to a cooling water-free zone on the underside of the discharge plate in the region of impact of the plastic strands. |
