Abstract: A bobbin changing device for feeding bobbins to and/or removing bobbins from a processing device which can wind a strand-form material onto a bobbin and/or from a bobbin, wherein the bobbin changing device has at least one conveyor device, wherein the bobbin changing device has a swivel fork which is suited for feeding bobbins to and/or removing bobbins from such a processing device and for feeding bobbins to and/or removing bobbins from the conveyor device.

Abstract: A winding spool for a transportable package is disclosed. In one aspect, the winding spool includes a first flange and a second flange, wherein the winding core top is arranged detachably with at least the first flange at the first end of a winding core top and is connected with the second flange. The conical hollow section of the winding core top has a thin-walled configuration. The conical hollow section has a length l between the first and second flanges, and an average wall thickness t. The conical hollow section has a modulus of elasticity in the range of 1000 N/mm2 to 30000 N/mm2. An aspect ratio of l/t is selected for this conical hollow section in dependence of the modulus of elasticity. The product of the modulus of elasticity and the aspect ratio can be greater than 0.1×106 and less than 2.5×106.

Abstract: The invention relates to a bobbin changing device (1) for feeding bobbins to and/or removing bobbins from a processing system (40) which can wind a strand-like material onto a bobbin and/or from a bobbin, wherein the bobbin changing device (1) has at least one conveyor system (30) which comprises, for example, two conveyor belts (31, 32), and a swivel fork (10). At least one bobbin receiving site (21, 22) on which a bobbin can be placed is formed on the swivel fork (10). By lifting, lowering and/or swivelling the swivel fork (10) in a specific sequence and repeating same, bobbins can be fed to the processing system (40) and the conveyor system (30) and/or removed therefrom and in this way a bobbin change can be carried out. The conveyor system (30) and the movement area of the swivel fork (10) may be at least partially interpenetrating.

Abstract: A spool is provided for receiving winding material, having a rotationally symmetrical, in particular conical, spool core for receiving the winding material, wherein the spool core has a first end and one or more first latch areas, and a first flange comprising one or more first latch elements. In order to enable the first flange to be mounted on the spool core as reliably as possible and with a simplified construction, one or more second latch areas are provided on the first end of the spool core and one or more second latch elements are provided on the first flange, wherein the second latch areas are formed on the spool core and the second latch elements are formed on the first flange, such that the second latch elements engage with the corresponding second catch areas when the first catch elements are engaged with corresponding first latch areas.
