Device for slipping winding cores onto expanding shafts with a given relative positioning

A device for placing a plurality of winding cores on an expandable winding shaft with a given relative positioning of the winding shaft, said device comprising:

• a stand,
• a frame mounted on said stand,
• said frame having sets of mutually parallel guide tracks for a coaxial, adjacent plurality of winding cores fed thereto in a transverse position and spaced from each other by said mutually parallel guide tracks,
• a distance between the guide tracks being equal to a width of the winding cores and a distance between the winding cores located on the tracks corresponds to a desired spacing of winding cores on the winding shaft,
• abutments and recesses located in front parts of said tracks for engaging foremost winding cores,
• tong-like grippers located in the stand for each respective winding core, said grippers having gripping jaws arranged to substantially simultaneously engage opposite sides of the winding cores, and
• the grippers and the frame being moved relative to each other so that the winding shaft may be inserted through aligned bores of the plurality of winding cores when the winding cores are separated from the tracks and held by the grippers.
