Machines
A.D. Rolling Machineries India designs and builds coil processing machinery in Gujarat — roll forming lines, slitting lines, cut-to-length lines and tube mills — plus the roll tooling and spares those machines run on.
Slitting Lines
Cut a wide coil lengthways into narrower coils.
10–36 cuts · 0.15–14 mm · coil up to 2200 mm
Illustrative rendering
Cut-to-Length Lines
Flatten a coil and cut it into sheets of exact length.
0.5–32 mm · coil up to 2600 mm
Illustrative rendering
Tube Mills
Form strip into a round or shaped tube and weld the seam.
10–20 stands · 0.5–10 mm · up to 2000 mm

Spares & Reconditioning
Shafts, spacers, roll re-grinding and re-profiling.

Roll forming
The thicker the steel, the more stands the line needs.
A heavier machine is used for the thicker range.

Final specification is confirmed per profile at quotation stage.
Sections our lines form
Every section below starts as one flat strip of steel and is bent into shape as it passes through the rolls.
These are sections the lines are designed to form.

Inside the machine
The forming stand
A pair of shaped rolls grips the strip and bends it a little further. A line has many stands in a row, each bending slightly more than the last.
Illustrative rendering
The slitter head
Rows of circular knives cut one wide sheet into several narrow strips. Knife spacing sets the width of each strip.
Illustrative rendering
The weld point
The strip is rolled into a tube and its edges heated by an induction coil. Two side rolls squeeze the hot edges together so they fuse into one seam.

Tooling & spares
Illustrative rendering
A roll forming machine runs on its tooling. When you add a new profile, or a roll wears, you need new or re-ground rolls. We make roll sets for our own lines and for machines built by others, and supply shafts, spacers and re-grinding.
