Abstract

Improvements in the apparatus for manufacturing screws, comprising a chopping mechanism for cutting the round bar into pieces, a mechanism for sharpening the pieces and a mechanism for upsetting the head of the screws, characterized in that the sharpening mechanism (3) comprises a turret disk (5) having in its circumference seats (6) for traces (2), a clamping cover (7) arranged along a portion of the circumference of the turret disk (5), a pin (8) of pressure arranged in an articulated joint mechanism (11) with a piston (12) and a spring (13), a head (9) of sharpening blades adjacent to the seat (6) in the working position and a weigher (10) of ejection that cooperates with the next seat (6) in the position of expulsion, the cutting mechanism (1), the sharpening mechanism (3) and the upsetting mechanism being joined by a conveyor (4).
