The Janome CoverPro 1000DX with electronic control is a uniquely designed, dedicated cover stitch only machine with 3 needles and a wide triple cover hem stitch.
It is not an overlocker. Its innovative design is based on the marriage of an industrial style cover hem machine and a convenient home sewing machine. The resulting union has produced a high speed, long arm, heavy duty cover hem machine, that looks and operates like a sewing machine.
The differential feed ratio, which is adjustable from .05 to 2.25, provides exceptional control for handling all types of fabrics and for creating desired special effects.
Threading is very easy due to color-coded thread guides. And when you lift the presser foot for rethreading, the thread tensions are automatically released so you can draw the thread smoothly.
The CoverPro 1000DX has been designed around a sewing machine rather than an overlocker. This means it sews like a sewing machine with all the dials conveniently located. It has a much larger arm space than competitor models and it has a freearm facility that is unique to this type of machine.
