摘要 |
Methods of making roofing products. One such method includes (a) creating a mixture having a filler and a polymer; (b) forming a sheet from the mixture; (c) cooling the sheet; (d) embossing the sheet; (e) forming multiple roofing products from the sheet; and (f) bundling at least some of the roofing products. Steps (a)-(f) are performed using an automated procedure. Another of the methods involves (a) creating composite roofing products using mold cavities; (b) using a robot to transfer some of the roofing products from some of the mold cavities to a conveying system; and (c) stacking together at least two of the roofing products that have different colors or different surface configurations.
