Process and device for producing a package of elongated winding material

A process for manufacturing a package with elongated winding material which can be transported without packaging, said process using a winding bobbin comprising a conical winding core having a longitudinal axis, spaced radially extending snap-in-juts, and a first and a second flange, in which the second flange on the winding core side having a smaller diameter is detachably connected to the winding core with the second flange having second radially protruding holding juts with spacing therebetween;

• including the following procedure steps in chronological sequence:
• composing said winding bobbin by assembling said detachable flange to said winding core, said assembling being performed by
• nserting the winding core into said detachable second flange in such a way that spaced radially extending snap-in-juts of the winding core are inserted into said spacing of said spaced radially protruding holding juts of said second flange;
• twisting the winding core and the second flange with respect to each other so that each snap-in-jut engages one holding jut, thereby establishing an axial connection between the second flange and the winding core;
• securing the connection between said detachable second flange and said winding core, by at least one locking element, said locking element being provided in said detachable second flange and being elastically deformed out of a first position when the snap-in-juts are inserted between the holding juts and moves back in its previous first position when said second flange and the winding core have been twisted, thereby establishing a radially secured connection such that the detachable flange cannot get loose from the winding core during winding and transport;
• integrating the winding bobbin into a winding device;
• receiving the winding bobbin in the winding device by means of two bobbin holding members, centering the two flanges and supporting them against the winding pressure on flange surfaces opposing the winding core, each of these surfaces being directed towards an adjacent bobbin holding member;
• winding up the winding material on the winding bobbin, said winding being controlled by a control unit such that a predetermined winding type will be formed on the bobbin;
• terminating the winding process and removing the winding bobbin from the winding device as soon as the bobbin is as full as desired.
