Abstract: A molding comprising a U-shaped trim molding in which is defined a channel and from which extends a fastener comprising one or more flexible shanks. Each shank extends from the trim molding and has a lip that extends laterally outwardly and downwardly away from the channel. The shank has multiple serrations in an opposing relationship with the channel. The molding is mounted to a structural support such as a pinch weld or panel with openings of struck-out portions by inserting a portion of the structural support into the channel and seating a lower edge of a return flange of the pinch weld or an edge of the opening or struck-out portion against one of the serrations on the lip of the clip. The resiliency of the trim molding and the shank helps retain the molding to the structural support and accommodates pinch welds of different sizes.

Abstract: A system for molding elongated ribbon-like products from thermoplastic materials utilizing a plurality of molds which are moved in tandem along a production line. As the molds are moved along the line at successive stations they are, while open, thermally adjusted to a temperature suitable for forming the product to be molded and then a ribbon of plastic is deposited in them. They are then closed and cooled and reopened and the molded product removed. The system utilizes only enough molding pressure to assure distribution of the plastic to all parts of the mold cavity and shaping of the molded product to the geometric design of the mold. The system includes a transfer means for the molds which returns the emptied molds for recycling through the molding process.
