A thought…borrowed from our good dealer in New Zealand, PPT Products. It is unwise to pay too much, but is unwise to pay too little. When you pay too much, you lose a little money! That is all. When you pay too little, you sometimes lose everything. Because the thing you bought was incapable of doing the things you bought it to do. The common law of business balance prohibits paying a little and getting a lot. It can’t be done! If you deal with the lowest bidder, it is well to add something for the risk you run. And, if you do that, you will have enough to pay for something better. John Ruskin 1819-1900

2 ROLL Machines/ Model 2R
HIGH SPEED, HYDRAULIC, TWO-ROLL SHEET BENDING AUTOMATIC OPERATIONS
The 2 roll machines feature a hardened and ground steel roll on top, with a large diameter roll in the bottom, made of high molecular density urethane. ONE PASS ROLLING with speeds of 4000+ parts/ day. These machines are the ultimate in high speed production of round shells in Aluminum, Stainless Steel, Copper and Steel. Punched, engraved and pierced plates do not deform with this method of rolling.
This method of rolling gives you perfectly round shells without flats at the lead-ing and trailing lips of the shell

SPECIALIZED CONE ROLLING MACHINES
HIGH SPEED, HYDRAULIC, TWO-ROLL SHEET BENDING AUTOMATIC OPERATIONS– Model 2R-K
The 2 roll machines feature a hardened and ground steel roll on top, with a large diameter roll in the bottom, made of high molecular density urethane. ONE PASS ROLLING with speeds of 4000+ parts/ day. These machines are the ultimate in high speed production of tapered shells in Aluminum, Stainless Steel, Copper and Steel. Punched, en-graved and pierced plates do not deform with this method of rolling. OMCCA snc has capitalized on this high speed phenomenon and has used it to roll cones to high levels of quality.
This method of rolling gives you the cones without flats at the leading and trailing lips of the shell

SPECIALIZED CONE ROLLING MACHINES
HIGH SPEED, MECHANICAL, FOUR-ROLL SHEET/ PLATE CONE BENDING OPERATIONS– Model DTS-K
4 ROLL Machines/ DOUBLE PINCH/ TAPERED ROLLS/ Model DTS-K Although cones are rolled on three and four roll standard straight roll machines. OMCCA snc has
researched this technology and has been designing and manufacturing very specialized cone bending machines. The machines are built on the DTS, HDTS and the 2R machine chassis. They
have conical tapered rolls which minimize the slip caused by the peripheral speed difference at the two ends of a cone being rolled. This solves many of the cone rolling shortcom-
ings of the classic straight rolled machines.

A SPECIAL PROJECT IN AUTOMATION:
This was a project undertaken by OMCCA in Sicily, in the town of Caltanissetta. The customer was LO CASCIO SALVATORE & C srl In 2001 a line of helical rolling of tanks was delivered. The material was mild steel 8mm thick, the machine had 6 meters length rolls and it was rolling tanks 1500mm to 2600mm diameter.
The basic idea is that of directly transforming the coil into a helical skin for tanks. This helical pipe was manufactured by unwinding a coil, automatic flatten-
ing, helical rolling, automatic welding from the inside using procedure 135 (EN 288) and from the outside using procedure 121 (EN 288) and subsequent plasma
cutting to the predefined length. The result of this production process is a pipe having geometrical and re-
sistance properties that are clearly superior to those that can be obtained with the classic straight rolling methods.
Indeed, as we had predicted, the result is a tank skin design that even without convex end plates, notwithstanding its considerable diameter compared to its
thickness, is basically self-supporting and so, in total unloading conditions, the distortion due to its own weight proves to be considerably less than what can be
encountered in metal sheets rolled using the traditional method. The concept of this structural stiffness is easy to understand if account is taken of the progress of the welding which, in fact, stiffens the pipe by following the helical cross-section of the metal sheet and contributes to the stability of the
structure with its transverse component.

CORRUGATED STEEL SHEET ROLL BENDING MACHINE
Model CORR
The CORR line of machines is basically a four roll double pinch machine. It was specifically designed for bending corrugated materials in steel and aluminum. Riveted corrugated steel tanks and agricultural silos are typical applications of formed sheet passing through the machine. The design is specific, because the requirement was for the machine to bend a corrugated sheet, which has a much larger section modulus (measure of stiffness) than the plane flat sheet. Thus, all the bending rolls have slide blocks at their ends sliding in guide-ways and are driven in translation via worm and pinion gear boxes. The rotation to the syn-chronized gear boxes is provided by hydraulic motors.

The frames are from high strength steel, laser cut, welded, stress relieved, sandblasted and then precision machined. Top and pinching rolls are driven by independent hydraulic motors. Rais-ing and lowering of the pinching roll is also accomplished by hydraulic motor/ worm and pinion gear boxes.
The drop-end is manual. Hydraulic is optional. Hydraulic units are by MARZOCCHI and the valves by DUPLOMATIC.

19
Roll sets with American and European corrugated steel sheet wave forms have been used on the CORR The most popular European wave is the 76mmX18mm with thickness ranging from 0,5mm to 2,0mm and also the American wave forms of 2.667" X 1/2" and 3" X 1", 0.034"- 0.168" thick.
Each CORR machine is made to customer requirements of width, wave size, material used, the thickness used and the radii which need to be rolled. So as such, there are no specifications of standard sizes. Please contact our sales department for optimized selection and discussion of the CORR machine
which will perform well for you and meet your expectations.
