Abstract
Abstract A process for the manufacture of filiform reinforcement elements of steel in the form of ribbons is improved by projecting a jet of liquid steel onto a cylinder rotating in a cooling medium and imparting a relative reciprocating movement parallel to the axis of rotation of the cylinder between the jet of liquid steel and the cylinder in order to undulate the ribbon in the direction parallel to the axis of rotation of the cylinder.

Process for the manufacture of filiform reinforcement elements of steel in the form of ribbons by projecting a jet of liquid steel onto a cylinder rotating in a cooling medium, characterized by imparting a relative reciprocating movement parallel to the axis of rotation of the cylinder between the jet of liquid steel and the cylinder in order to undulate the ribbon in the direction parallel to the axis of rotation of the cylinder.
Claim 2
Dependent Claim
73 words
Process for the manufacture of filiform reinforcement elements of steel in the form of ribbons by projecting a jet of liquid steel onto a cylinder rotating in a cooling medium, characterized by imparting a relative reciprocating movement parallel to the axis of rotation of the cylinder between the jet of liquid steel and the cylinder in order to undulate the ribbon in the direction parallel to the axis of rotation of the cylinder.
Claim 3
Dependent Claim
23 words
Process according to claim 1, characterized by imparting a reciprocating movement to the jet parallel to the axis of rotation of the cylinder.
Claim 4
Dependent Claim
20 words
Process according to claim 1, characterized by imparting a reciprocating movement to the cylinder parallel to its axis of rotation.
Claim 5
Dependent Claim
35 words
Process according to claim 1, characterized by thereafter passing the undulated ribbon between two grooved rollers in order to also undulate the ribbon in the direction perpendicular to the axis of rotation of the cylinder.
Claim 6
Dependent Claim
24 words
Process according to claim 2, characterized by traversing the jet with an alternating electric current and passing the jet through a constant magnetic field.
Claim 7
Dependent Claim
24 words
Process according to claim 2, characterized by traversing the jet with a constant electric current and passing the jet through a variable magnetic field.
