    摘要： The method of deforming a thermoplastic projection (20) of a workpiece (14) comprises coupling laser energy to the projection (20) for heating the projection and rendering it deformable, and while the projection is deformable, deforming it to a predetermined shape. The apparatus comprises a support (12) for supporting a workpiece (14); a source of laser energy (24) disposed for causing a laser beam (26) from said source to shine upon the projection (20) of the workpiece (14) disposed on said support (12) for heating the projection (20) and rendering it deformable; a die (30) having a shaping surface (32) disposed for engaging and deforming said projection (20) when said projection (20) is rendered deformable, and motion means (34) coupled to said die (30) for providing during a time interval forced engagement between said shaping surface (32) and said projection (20) for deforming said projection.

    摘要： A method and apparatus for forming a seam on a thermoplastic coated container, which container has been formed from a single blank (6) or a continuous by bending a substrate member (4) from which container was formed and overlapping edges (22, 24) thereof to form the seam. According to the practice of this invention, the edges (22, 24) of the substrate member (4) which are to be over-lapped and joined to form the seam are each heated, prior to their overlapping, by energy from a laser (16) to thereby render the thermoplastic coatings on the overlapped portions of the substrate member soft and tacky so that they will adhere to each other when pressed together and allowed to cool. The laser energy is applied by directing an unfocused laser beam of 10.6 µm wavelength over a zone of about 1,26399 cm (one-half inch) in width to each other to the two edges (22, 24), the web or blanks (6) being fed along a conveyor (12) past the stationary laser sources (16).
