摘要:
A method and apparatus for accurately slitting a rod into two equal sections in which the rod is longitudinally advanced to a slitter and is laterally shifted by an in-line guide adjustment system or 1GA so that the slit sections will be equal. The rod sections are measured by the 1GA after slitting to evaluate any difference in size therebetween while the sections are advancing, and the 1GA transversely shifts the rod before it enters the slitter to eliminate any size differential between the slit sections.

A method and apparatus for transferring rod sections from a flying shears to a cooling bed via a run-in table wherein electromagnetic coils are placed in hollow rollers at a downstream end of the run-in table to pull the leading ends of the rods onto the rollers and prevent bouncing of the rods whereafter braking force is applied to the trailing end of the rods before the rods are lifted by a lifting apron for transfer to the cooling bed. The rollers containing the electromagnetic coils are hollow and detachable to gain access to the interior of the rollers and the electromagnetic coils therein.

A no-twist ("NTA") apparatus and method for manufacturing steel reinforcing bar which allows steel reinforcing bar to be manufactured with greater speed and precision than by conventional methods. The NTA method employs numerous stands, with the shafts of the rolls of the first two stands offset 45.degree. from a predetermined plane and 90.degree. from each other. The third and fourth stands comprise rolling and splitting stands and are the shafts of their rollers are perpendicular or parallel to the predetermined plane and form equal angles with the shafts of the first two stands so that the bar can be fed to the rolling and splitting stands without intermediate twisting and the single bar can be split into a plurality of bar segments. The remaining stands are arranged into at least two lines of stands, in each of which the sides of the rolls of the first stand are offset 45.degree. in a first direction from the predetermined plane and the sides of the rolls of the second stand are offset 45.degree. in a second direction opposite to said first direction relative to the predetermined plane. Alternatively, the sides of the rolls of the first and second stands in the two lines are respectively offset either by 90.degree. and 0.degree. or 0.degree. and 90.degree..
