Abstract
A method for rolling a rigid vinyl siding elongated sheet of selective dimensions into a convenient transportable compact coil for easier handling and shipping, and products derived from practicing the method. The method includes rolling the sheet onto a spool having a particular axle shape and diameter which varies with the thickness and design of the siding. The shape of the coil may be determined by the shape of the spool axle. For example. the use of a tapered-shaped axle diameter for the spool may produce a substantially conical-shaped coil. Thus, a predetermined length of siding can be rolled with an appropriate spool size to produce a coil product of a desired shape. A method step relates that the granular side of the siding initially contact the surface of the spool and that the smooth side of the siding face outwardly. Fasteners hold the compact coil in a secured manner before the coil is boxed for shipment. In an alternative embodiment, an insert and support spacer sheet made of cardboard or the like is utilized in rolling the siding sheet into a coil.
