    摘要: This invention relates to a dual composition bar and extrusion nozzle therefore. The bar is formed of two different materials, preferably of separate colors, and has substantially sinusoidal upper and lower surfaces with a tongue and groove interlock therebetween. The extrusion nozzle utilizes two dies, the first of which has two die portions separated by a die element for forming a tongue and groove interlock between the two materials. The die element does not extend to the second die wherein the convoluted die portions squeeze the two materials together enhancing the interlock.
