Abstract: An automatic machine for producing reinforcement blanks, in particular of the type of reinforcement chairs, the automatic machine comprising two outer moulding units (A, A?) and two inner moulding units (B, B?), wherein each of the moulding units (A, A? and B, B?) comprises a pair of mandrels—a movable mandrel (8, 5) and a stationary mandrel (7, 6) connected to a power mechanism (11, 2). A method for producing reinforcement chairs from reinforcement sections comprising simultaneously forming the two support legs of the reinforcement chair in mutually opposite directions by the two outer moulding units (A, A?) and then simultaneously forming the two vertical supports of the reinforcement chair by the two inner moulding units (B, B?).
