    • An assembly for reshaping an elongated plasticized article includes a heated fixture upon which the elongated article is supported in adhering fashion to a contoured upper surface. Following heating, the article is transferred to a cooling fixture exhibiting a further contoured upper surface and, upon subsequent cooling, the article exhibits a final multi-dimensional extending profile matching the contoured upper surface of the cooling fixture. A further variation of the assembly includes an elongated and bowed track supporting a fixed jig at an end thereof. A slidable jig is traversable along the track and actuated by a ram in directions towards and away from the first jig. Upon a first length extending portion of the article being pre-secured to the slidable jig, a first forward feed direction of the article results in an end extending portion communicating within a multi-dimensional cavity establishing a contoured surface withing the fixed jig, subsequent rearward displacement of the slidable jig causes forcible reshaping of the elongated article as it is stretched and drawn against the contoured surface of the fixed jig.
    • 用于重塑细长的塑化制品的组件包括加热的固定件,细长制品在其上以与轮廓的上表面的粘合方式支撑在该组件上。 在加热之后,将物品转移到具有进一步成型的上表面的冷却固定装置中,并且随后冷却时,制品展现与冷却装置的轮廓上表面匹配的最终多维延伸轮廓。 该组件的另一变型包括在其一端支撑固定夹具的细长弓形轨道。 可滑动的夹具可以沿着轨道移动并且由冲头沿着朝向和远离第一夹具的方向致动。 当制品的第一长度延伸部分被预先固定到可滑动的夹具上时,制品的第一向前进给方向导致端部延伸部分在多维空腔内连通,从而与固定夹具建立轮廓表面,随后向后 可滑动夹具的位移导致细长物品在被拉伸并拉到固定夹具的轮廓表面上时被强制重塑。
