THE CUTTIN’LINES® CONCEPT : PRODUCTIVITY AND scope of application and anticipated benefits Based on its wide standardised coil feeding lines program, DIMECO offers a large range of Cut-To-Length and slitting lines showing outstanding price for value. Annual capacity of a Cut-To-Length line DIMECO Cut-To-Length lines are suitable for coils from 100 kg to 33 tons and up to 2 metre wide. WHY INVESTING IN A CUT-TO-LENGTH LINE ? At manufacturers, the decision, is based on a “make or buy” analysis between purchasing blanks from service centres or in-house manufacturing on a new Cut-To-Length line,...

FLEXIBILITY line structures and development process The training of your operators is often carried out in your own language thanks to the international network of DIMECO agents. Decoiler Short line layout LINE LAYOUTS A Cut-To-Length line is generally made up of a coil management and decoiling module, a device for straightening the strip, a shearing system and a blank packaging module. The “conventional” layout of the line reveals a loop and a start-stop shear. It enables relatively high output and significant versatility. The “short” line which integrates a combined straightener-feeder, is...

COIL MANAGEMENT AND DECOILING At 30 m/min, only 30 minutes are required to fully consume a 8 t coil. (1000 mm x 1mm). Double decoiler NUMEROUS COIL CHANGES The high decoiling speed of a Cut-To-Length line leads to frequent coil changes. Furthermore, sites following the “Lean manufacturing” practices are constantly seeking cuts in inventories. They only cut the number of blanks required for subsequent production, thus multiplying the number of coil changes. The Cut-To-Length line operator often has to change the coil more than 10 times per shift. Without special attention to the changeover time,...

FLATTENING THE STRIPS WHICH DEFECTS TO BE CORRECTED ? High quality coils only present a single shape defect i.e. the coiling defect called “coil set”. With coils of a lesser quality, other defects may be found (crossbow, camber, long or wavy edges, centre buckles) which may be more difficult to correct with the straightening equipment. When it crosses the straightening rollers, the strip passes through a succession of alternate deflections. Depending upon the design of the straightening machine and its adjustments, a variable portion of the strip thickness exceeds the yield strength of the material....

SHEARING AND STRIP PREPARATION The shear is the machine which generally defines the speed of the Cut-To-Length line. Flying shear Oscillating shear THE CUTTING SHEAR The shear is obviously the key machine in the CutTo-Length line. Depending up on the output rate, thicknesses and types of material to be cut, one may opt for a pneumatic, hydraulic or electromechanical shear. Pneumatic shears are reserved for light applications for cross sections less than 650 mm2. Electromechanical shears enable highest output and big cross sections. Hydraulic shears enable cutting of the largest sections but are...

SLITTING AND RECOILING LINE STRUCTURE DIMECO slitting lines feature reasonable performances, well suited to the requirements of Original Equipment Manufacturers wishing to integrate the slitting process in their works. The production process of coils at steel mill results in variable thicknesses within the strip. Indeed, the strip centre shows a slightly greater thickness than the edges. After slitting, the recoiling of several strips on the same mandrel results in different linear speeds. The differences are greater as the thickness is less and the number of cuts is increased as the coil quality...

STACKING AND PACKING SECTION Well designed packaging facilitates storage and subsequent operations. A WIDE RANGE OF SYSTEMS The design of the stacking system will depend up on numerous parameters: line speed, size and weight of the blanks, type of material, complexity of the stacking pattern. We can arrange the output of your Cut-To-Length line by selecting various features from a wide range of available solutions. GRAVITY PROCESS For basic applications, a simple retractable flap system implemented immediately after the shear will be adequate. The blank will be dropped onto the pallet and positioned...

OTHER INTEGRATED FUNCTIONS countless possibilities The PROFIBUS system ensures straightforward networking of various machines and accessories. Lengthwise shear HIGH PERFORMANCE LINE SUPERVISION A DIMECO Cut-To-Length line is monitored by standardised SIMOSTAR® control based on the SIMOTION® technology from SIEMENS®. It offers numerous possibilities of control and interfacing with other devices (Profinet, Profibus, Ethernet, etc.). On the basis of an optimised kernel, DIMECO engineers develop programs specific to your application. The colour graphic touch screen terminal is programmable in Wincc....

FROM THE CUT-TO-LENGTH LINE TO THE F.M.S. a very simple step to make TINUOUS FORM The addition of a few punching or forming operations improves the profitability of the Cut-To-Length line. LINAPUNCH® MC-E N.C. punching machine variable feed-length The MULTISTEP punching technology : principle SCRUTINISE DOWNSTREAM MANUFACTURING OPERATIONS The majority of blanks produced from a Cut-ToLength line later undergo other punching or forming operations. A more cost effective process is obtained by achieving the greatest number of operations possible on the Cut-To-Length line before packing the blank....
