1394303 Clips ILLINOIS TOOL WORKS INC 19 Jan 1973 [19 Jan 1972] 2920/72 Heading E2B [Also in Divisions B6 and C3] A moulding clip comprises a body portion from which extend fastening means designed to receive a member to 'be mounted, there being a recess in one surface of the body portion and, secured to the body portion within the recess, either a dry layer of a thermosetting composition that 'becomes adhesive on heating, the composition comprising a mixture of acrylonitrile polymer and phenolic resin or an adhesive tape comprising a sheet or strip carrying a layer of the thermosetting composition at least on its exposed side, the thickness of the layer or tape being greater than the depth of the recess. Preferably the composition also contains a coumarone-indene resin. The composition may additionally comprise a sterically hindered phenol, e.g. octadecyl 3-(3, 5- di-tertiary-butyl-4-hydroxyphenyl) propionate. Preferably the thermosetting composition comprises 20-140 parts of a canboxy-modified butadiene-acrylonitrile copolymer, 100-200 parts of the phenolic resin and 1-10 parts of coumarone-indene resin. Preferably the sheet or strip is a sheet or tape of flexible polyurethane. One or both surfaces of the sheet or tape may carry the thermosetting composition. The layer may be applied from a slurry or solution. As shown in Figures 4, 5 and 6 a moulding clip 30 has a main body portion 31 behind which is secured thermosetting adhesive tape 10 positioned within a recess 32. Clip 30 includes transversely extending tab segments 35 which prevent the metal moulding strip from coming into actual contact with the painted surface adjacent the clip. Clip 30 also includes a pair of parallel resilient undersections 33 and 34 which are flexed inwardly towards one another upon applying a moulding strip thereto. To ensure proper gripping the outer surfaces of the resilient finger portions 33 and 34 are angled as seen in Figure 6. The moulding clips are applied to the car body by heating. As shown in Figure 8 a moulding strip 39 is secured by means of clip 30 secured with adhesive tape 10 to door 41. Moulding 39 has inwardly turned edge portions 42 which are forced over the inclined surfaces 36 and come to rest against the tabs 35 and grip the inclined surface 37. A plurality of clips can be secured in spaced apart positions to a continuous sheet or strip of adhesive tape and each of the clips can be severed from the strip and applied as desired. |
