  • Device for controlling supply of a filament
    Patent number: 11167493
    Abstract: The present invention relates to a device (10) for controlling supply of a filament (14). The device (10) includes a grooved rotatable wheel over which the filament (14) runs and biasing means (22 & 24). The wheel (12) has a hub (16) and a pair of flexible flanges (18 & 20) extending radially from the hub (16). The biasing means (22 & 24) are adapted in use to force the flexible flanges (18 & 20) to bend towards each other so as to embrace the filament (14) thereby pressing the filament (14) tight against the hub (16).

  • Apparatus and method for retreading tires
    Patent number: 9889617
    Abstract: The present invention relates to an apparatus (10) and a method for retreading a tire (16) having a worn surface (12). The worn surface (12) is made of a thermoplastic elastomer. The apparatus (10) includes a heater (34) and a 3D printer (18). The heater (34) is adapted to heat up the worn surface (12) to a desired temperature. The 3D printer (18) is adapted to lay one or more layers of the thermoplastic elastomer onto the heated worn surface (12). The or each layer of thermoplastic elastomer is capable of adhering to the heated worn surface (12) or previously laid layer without requiring an adhesive medium or agent.
