Machine Direction

The direction that is parallel to the direction of the movement of the forming wire on a papermaking machine. It is the forward movement of the forming paper web on the forming wire that induces the paper's grain. The machine direction is also called the grain direction. The direction perpendicular to the machine direction is known as the cross-machine direction, or the cross-grain direction.
