An automatic rolling machine with flat chasers, comprising a motionless plate and a movable plate that is fixed to a support that has a reciprocating motion actuated by a chuck, by means of a rod-and-crank system, the chuck being rigidly coupled to a base. The base comprises a first motionless part, which is rigidly coupled to the frame of the machine, and a second movable part, which constitutes the support of the chuck, the position of the movable part with respect to the motionless part being adjustable by a means for varying the position of the movable part with respect to the motionless part.
