  • Plastic reel for material winding
    Patent number: 5379965
    Abstract: The reel comprises a two-part core 2 with a shape of a hollow cylinder, with a flange 3 at each of its two ends. The flange 3 and the core 2 are positively engaged in the circumferential and radial direction, and are connected to one another by at least four detachable connection elements per flange 3. By means of this design, large forces and torques can be transferred between the flange 3 and the core 2 so that larger reel diameters of plastic can also be constructed.
