The MESH LINE CO240-A line has been devised and manufactured to produce electrowelded wire mesh panels in standard or standardized size for big production lots and to be used for 24 hours a day.
It is fed in continuous with line wires by coils while with cross-wires by pre-straightened bars.
The line is available in two configurations:
Configuration 1
CO-A 		Configuration 2
CO-A-MULTISTEP



Configuration 1

 back to top

SVV-3T

Line-wires coils holder:

Steel structure with vertical axis decoiler suitable to uncoil metal coils having a maximum capacity of 3.000 kilos each.
The installation is equipped with double pneumatic breaking system.

RAS

Line-wires guides:

Steel structure suitable to drive the line-wires from the decoilers towards the straightening/towing group.
Besides driving the line-wires, it stops the whole line in the absence of wire.

RAD-5

Line-wires straighteners:

Steel structure on which the single straightening groups suitable for wires from 4 to 10 metres are assembled.
By means of two levers it is possible to adjust all groups at the same time and quickly (in a few seconds).
It is also possible to adjust each roller one by one.

TR

Line-wires drawing system:

Steel structure made up with two towing units and a device to check and align the line-wires by operating on the forwarding speed.

RAD-WEL

Line-wires straighteners:

Steel structure on which the single straightening are assembled.
It is also possible to adjust each roller one by one.

AV

Line wire advance system (roller advance):

Steel structure fitted on the welder body. The single towing groups for each line-wire are assembled on a spline shaft.
The correct forwarding movement of the wire mesh is gained by using n° 2 servomotors and a correct pneumatic pressure exerted by the upper rollers onto the wire.
The operator can set the forwarding movement of the wire mesh (interaxis of the cross-wires) with 0.1 mm increases and guarantee of absolute exactness, from the control console.

CO-A

Mesh welding machine:

Steel structure where the welding transformers (from 6 to 12) and all accessories (lower and upper electrodes, welding presses, position electromagnets and so on) that allow welding of smooth and ribbed wires with diameter from 4,0 to 10,0 mm, are placed.

ATR

Cross-wire feeder:

Steel structure assembled on track movable trolley. It feeds the welder in automatic mode drawing the cross bars from a big magazine (2 tonnes). It is equipped with n°2 servomotors; one moves the feeding disc and the other pushes the bar below the welding presses.
It is suitable for wires having diameters from 4 to 12 mm.
It can feed up to 130 bars per minute.

ACW

Automatic Cross Wires Feeding System (optional)

COM.IT has developed a new device to automatically feed the magazine loader "ATR" of the welding line called "CO-240-A".
The wires are held by two spools placed on rotating reels with pneumatic braking.
Towing and straightening are carried out by two straightening machines.
The cutting table and the support structure are designed so as to be able to straighten, cut and unload wires with length from 1400 to 2500 mm and a diameter from 3,0 to 10,0 mm.
ACW can be installed on new welding lines or in the revamping of existent plants.

CUT

Line wire shear:

Sturdy structure moving on tracks.
The machine is suitable to cut n°24 wires (diam.10 mm) at the same time with no need to stop production line during cutting operation.

RIB6

Turning-stacking unit:

With this unit the operator can:
  • Extract the already cut panels by the shear
  • Turn and stack the wire mesh panels
This operation allows halving the size of the produced material, and saving money both in the storing and moving operations.

ROLL 6,5

Roller conveyor:

the motorized roller table, placed after the turning-stacking unit, allows having a station to tie and evacuate the produced wire mesh packs, with no need to stop production line.

CON-240A

Electrical control cabinet:

the box is completely sealed and thermically conditioned, and it contains all necessary components to make the line work and to check it.

Control unit of the line:

touch screen display to:
  • Program the types of wire mesh to produce.
  • Store up to 100 different types of wire mesh.
  • Check and vary the production parameters.
  • Display production statistics
  • Display error messages

Control unit TR:

touch screen display to:
  • Select the wires to use
  • program slow or fast towing speed

Control unit RIB6:

for the working and checking in manual or automatic of the turning-stacking unit.

ICE057

Water cooler:

This is a water cooling unit suitable to cool water at the exit of the welder (transformer, current cables and electrodes) and of the control board (SCR).

AIR300

Compressed air station:

It is made up with:
  • compressor
  • dryer
  • tank
  • filter

It is dimensioned according to the Customer’s requirements.

INT

Intermediate extractor:

This unit is necessary to extract the wire mesh panels from 2.500 to 4.000 mm in length.

CO-A-MULTISTEP

Mesh welding machine:

Steel structure where the welding transformers (from 6 to 12) and all accessories (lower and upper electrodes, welding presses, position electromagnets and so on) that allow welding of smooth and ribbed wires with diameter from 4,0 to 12,0 mm, are placed.
The forwarding movement of the wire mesh is driven by a servo-motor that moves forward a trolley carrying the pneumatic drawing grippers.

The operator can set the forwarding movement of the wire mesh (interaxis of the cross-wires) with 0.1 mm increases and guarantee of absolute exactness, from the control console.
