Abstract (en)

Device and process for the regulation of thread winding onto a bobbin (10) by applying a desired contact pressure P c of the operating bobbin, providing the bobbin-holder arm (11) with a counterweighing counterthrust P p , on the basis of a pre-established trend of the value of P c in relation to the advance length of the bobbin (10), indicating the weight of the bobbin (10) in relation to the ratio between the length reached and indicating the rising ± angle of the bobbin-holder arm (11), calculating the weight component due to the bobbin (10) and said arm (11) and applying a counterthrust Pp equal to the difference between said component and the pre-established value of the contact pressure P c referred to the length reached.
