The present invention provides a method for distributing paste using a paste distributor mechanism and an atmospheric pressure feeding device using the method. In the method, the paste distributor mechanism horizontally moves a distribution head at a distribution speed relative to the workbench to distribute the paste to a substrate to form a paste pattern having a straight line portion and a curve line portion. The distribution head containing the paste passes through a nozzle driven by a distribution pressure; the workbench is provided with substrates. Steps of the method are showed as follows: reducing the distribution speed from the straight line distribution speed to the curve line distribution speed from the starting position of the curve line or from a precalculated position in front of the starting position of the curve line to another precalculated position in front of the ending position of the curve line; then maintaining the distribution speed at the curve line distribution speed from the speed reducing starting position to the ending position of the curve line or to the speed increasing starting position in front of the ending position of the curve line; reducing the distribution pressure from the straight line distribution pressure to the curve line distribution pressure from the speed reducing starting position to the speed reducing ending position; then maintaining the distribution pressure at the curve line distribution pressure from the speed reducing ending position to the speed increasing starting position.
