BOBBIN AND DEVICE TO DETERMINE PROPERTIES OF BOBBIN MATERIAL

摘要

FIELD: textile, paper.;SUBSTANCE: bobbin comprises a cartridge and a large number of material layers wound on it. The material is a tape or a thread. At least one marking is provided on the bobbin. The marking is made as a specific variance in the laying angle. An rpm sensor is connected to the bobbin. When reeling on the marking section, the sensor produces an output signal. When reeling on sections without marking, the output signal is not produced. The output signal of the sensor is transmitted to a computing device. From the computing device the signal is sent to a control and processing device.;EFFECT: making it possible to early detect approaching of the thread end.;12 cl, 4 dwg
