There are provided a vehicle interior finishing laminate sheet in which a polypropylene resin foam board of high foaming extent having interconnected cells is used as a core member, a vehicle interior trim material, a method for manufacturing the vehicle interior finishing laminate sheet, and an apparatus therefor. The present invention relates to a vehicle interior finishing laminate sheet 1 provided with a core member consisting of a polypropylene resin foam board 2. The polypropylene resin foam board 2 is extrusion molded into a plate shape, and has an interconnected cell ratio of 50% or higher and a foaming extent of 10- to 50-fold. A plurality of polypropylene resin foam boards 2, 2 are joined to each other by the hot plate welding method or the laser transmission welding method, whereby a large-size core member of vehicle interior finishing laminate sheet 1, which is used for a roof lining or the like, can be formed.

An attaching construction includes a first member having a circular tubular welding portion at a distal end and, at a rear end thereof, a holding portion which is integral with the welding portion. The attaching construction includes a second member having an annular first positioning rib, and an annular second positioning rib inside the first positioning rib. The welding portion is positioned within the first positioning rib, and the welding portion is friction welded in place within the first positioning rib while the first member is rotated.

A support coil for radially supporting an elastically expanded tube material includes an extruded profile body consisting of a plurality of windings wound about a longitudinal axis of the support coil. Each of the windings has opposing end faces. A ratchet arrangement joins the end faces of the adjacent windings with respect to the longitudinal axis of the support coil. A tongue and groove arrangement joins the end faces of the adjacent windings with respect to a radial direction of the support coil. The tongue and groove arrangement is spatially separated from the ratchet arrangement.

A method of forming a unitary, composite structural member, and a member formed in accordance with the process. The process involves stitching a plurality of warp knit panel sections together to generally form a plurality of independent panel sections. The sections are placed within the dies of a molding tool such that a rib portion of each section aligns. Inflatable bladders are then slipped into voids formed in between the various panel sections of the assembly. The bladders are inflated to hold with one another. Resin is then infused into the panels that make up the assembly. The assembly is then cured. When the panels are removed from the molding tool a unitary, complexly shaped, composite structural member is formed.

A multiple lap-joint for sheets of thermoplastic laminates, the laminates having edges separated by high temperature removable film separators. The laminate sheets are heated under pressure and formed. The separators are then removed and the feathered edges of two adjoining sheets are interleaved and the sheets are reheated under pressure forming an integrally formed lap-joint.
