Abstract (en)
A device for automatic wire tension adjustment during the various steps of winding in machines for winding electric coils, comprising a supporting structure (2) that supports a series of elements that define a path for the wire (3) to be fed to the coil being wound; along this path there are means (5) for detecting the tension of the wire (3) and a takeup arm (6) that can rotate about an axis (7) with respect to the supporting structure (2) due to the variations of the tension of the wire (3); the device further comprises, along the path for the wire (3), an element (4) for pushing and braking the wire (3) and means (8) for detecting the rotation of the takeup arm (6) about the axis (7) relative to the supporting structure (2) and the means (8) for detecting the rotation of the takeup arm (6) are connected functionally to the pushing and braking element (4) for an automatic adjustment of the degree of thrust or braking applied to the wire (3) as a function of the detected value of the rotation of the takeup arm (6) about the axis (7).
