Abstract (en)
[origin: WO2010028642A1] The aim of the invention is to devise a contactless method for controlling the thickness of a preparation layer applied to a yarn and a circuit arrangement for carrying out said method which allow the monitoring and optionally the control of the preparation application online and continuously during the production process of the filament yarn spinning on every spinning nozzle and which also allows already existing textile machines to be retrofitted. According to the invention, the field effect is directly detected via the induction effect caused by it and without first compensating it. As a result of the induction effect, an electrical voltage which is proportional to the induction is generated and the electrical voltage is evaluated in terms of its level and curve. The invention also relates to a contactless method for controlling the thickness of a preparation layer applied to a yarn and to a circuit arrangement for carrying out said method.
