ABSTRACT:
An apparatus and method for producing elongate variably shaped bodies at least partially comprising thermoplastic material a profile is extruded from an extrusion system head and engaged in a flexible conduit created by cavities formed inside a series of calibration plates attached flexibly together. The calibration plates slide freely over a rotating mold to adopt the shape of the mold's outer contour. The profile is driven through the flexible conduit and winded around the rotating mould like coils. In an embodiment of the apparatus and method, the profile is winded around a size-variable mould creating three-dimensional objects in real time.
