Multi-format cutting lines

The levellers commonly used on these lines come in 3 heights, and can process materials with a maximum thickness of up to 4-5 mm. As with the cross-cutting lines, these levellers are equipped with functions such as automatic cassette changing (< 5 min), LSA (Leveller Setting Assistance), a roller cleaning system, levelling roller materials and finishes, and other features.

Depending on the speed of the line, the material to be processed and its thickness, the shears used in this type of line are:

• Rotary shears: These are intended for high-production lines (up to 200 cycles/minute) in which the shear cuts the material by means of the synchronised rotation of the upper and lower head. They are lines that work by pulling, and feeding is controlled by a pre-feeding roller and measuring wheel. Because the lines work by pulling, they do not need a pit and therefore are simple installations. The shears are equipped with a blade change feature and automatic clearance adjustment.
• Transversal shears: These cut from top to bottom and therefore have the highest accuracy in terms of cutting linearity. In addition, because the material is stationary at the time of cutting, these shears achieve minimum burr values. On the other hand, the productivity of these shears is lower than that of the presses, since they are lines that work in a pit and the feeding is done cyclically. The shears are equipped with an automatic die change feature (to make curved cuts, omega cuts, etc.) and automatic clearance adjustment.
