Abstract
An in-line process for forming pre-finished siding manufactured from cellular poly vinyl chloride comprising embossing, milling, parting, punching, and coating the poly vinyl chloride such that the resulting siding is suited for use in an environment exposed to a wide range of fluctuating temperatures and moisture. The process accommodates the natural expansion and contraction of cellular poly vinyl chloride by producing a novel milled clapboard configuration that, when used as siding, can be installed to create a historically correct clapboard installation.
Claims19
A cellular poly vinyl chloride clapboard siding formed from a method comprising:
- profiling a cellular poly vinyl chloride board in a moulder to yield a two-up back-to-back configuration, wherein the profiling comprises:
- milling a first end and a second end of a cellular poly vinyl chloride board to form a profiled end, a radius, and a lower assembly groove on each of the first and second ends;
- milling a first and a second face of the cellular poly vinyl chloride board to qualify a thickness of the board;
- and
- milling a first saw groove and a first upper assembly groove on the first face and a second saw groove and a second upper assembly groove on the second face;
- sawing the profiled cellular poly vinyl chloride board at the first and second saw grooves to yield at least two cellular poly vinyl chloride clapboards;
- and
- coating the cellular poly vinyl chloride clapboards with a polyurethane based coating.
A cellular poly vinyl chloride clapboard siding formed from a method comprising:
- feeding a cellular poly vinyl chloride sheet into a gang rip saw at a speed of about 20 feet per minute;
- cutting the cellular poly vinyl chloride sheet into a plurality of cellular poly vinyl chloride boards;
- conveying each of the cellular poly vinyl chloride boards into a moulder at a speed of about 100 feet per minute;
- milling each of the cellular poly vinyl chloride boards;
- conveying each of the cellular poly vinyl chloride boards to a band type sawing machine at a speed of about 100 feet per minute;
- parting each cellular poly vinyl chloride board with a band type sawing machine to form individual cellular poly vinyl chloride clapboards;
- feeding the cellular poly vinyl chloride clapboards to a paint application booth at a speed of about 200 feet per minute;
- coating the cellular poly vinyl chloride clapboards with a polyurethane based coating;
- and
- drying the coated cellular poly vinyl chloride clapboards, wherein drying comprises exposing the coated cellular poly vinyl chloride clapboards to about 10 minutes of flash-off time at ambient temperature, to about 20 minutes of cure time at approximately 125 degrees Fahrenheit, and to about 10 minutes of cool down.
