Abstract (en)
[origin: US4593865A] The winding mandrel comprises a cylindrical winding drum or body which has two circumferential web members on its inner side. Each web member lies substantially in a plane which lies outside the center of gravity of the winding mandrel together with the coil or wound package. The winding mandrel bears upon two driven and tandemly arranged support wheels with one of its web members. A support roll is arranged beneath these support wheels. A lateral support surface of the web member bears against this support roll. The support wheels are constructed as friction drive wheels and, in addition to supporting the winding mandrel, serve to drive the winding mandrel. Due to the overturning or tipping moment induced by the eccentricity of the bearing points of the winding mandrel upon the support wheels in relation to the center of gravity, the winding mandrel is pressed against the support roll. This has the effect that the winding mandrel maintains the desired position during its rotation. This position is partly determined by the support roll constituting a contact roll arranged to be immovable in the direction of the longitudinal axis of the winding mandrel.
