CoverPro 900CPX Coverstitch Machine The Janome coverstitch 900 CPX is an innovative design based on the marriage of an industrial-style cover hem machine and a convenient home machine to bring you the perfect home coverstitch machine. The resulting union has produced the Janome 900CPX, a high-speed, long arm, heavy-duty cover hem machine that looks and operates as easily as a sewing machine but with wonderful coverstitch results.
