Abstract

Method and corresponding apparatuses for manufacturing screw-tips with sections of various shapes characterized in that rounds of steel or another metal or alloy of several of suitable diameter are converted by one or several passages between the rollers of a mill in wires of quadrangular triangular section pentagonal hexagonal or other multilateral and the wires thus obtained are transformed by one or more steps between other rollers of the rolling mill into wires with star-shaped section of three four five six or more points with concave sides and protruding edges whose protrusions after subjecting these wires to a mathematical twist constitute to the exclusion of the use of all ordinary threading machinery and all loss of material the screw thread of our cold-stamped screw-tips with or without a head after twisting operation.
