METHOD AND DEVICE FOR MAKING COMPOSITE SHEETS |
摘要 |
<p>The invention concerns a method for making composite sheets consisting in: introducing continuously at least one yarn layer, this layer comprising at least two materials having different melting points, in a zone where it is heated at a temperature ranging between said melting points and less than the degradation temperature of the material having the lower melting point; passing over the layer at least a turning bar heated at a temperature ranging between said melting points and less than the degradation temperature of the material with the lower melting point; compressing the layer as it comes out of the bar or bars and cooling it so as to form a composite strip; collecting the strip in the form of one or several composite layers. The invention also concerns a device for implementing the method as well as the resulting products.</p> |
