This "STANDARDIZED" Line Model is for slitting a mother-coil, maximum 1500mm wide, to narrower strips that, can either be cut to length and stacked or recoiled.
It can also single-blank, or rewind full-width complete or lighter-weight coils with no slitting operation.

When slitting and recoiling, the max. line speed is 75m / min; when blanking/multi-blanking, it is ca. 20-25m / min 'on average' (varying with the parts length).

Workcycle (blanking/slitting/recoiling), function/s of each line part

The coil is loaded onto the decoiler mandrel using the coil car.

> "Loop" & "pull" modes: when processing thin material, this is left hanging free on loop between the decoiler and the straightener/slitter unit; with thicker material, the straightener/slitter pulls the material from decoiler.

The straightener's work rolls, although they are supported by back-up rolls may leave small marks onto sensitive materials. Therefore it is not advisable processing these with the line.

The slitter is equipped with 15 pairs of slitting knives. The minimum strip width is 40 mm.

The guillotine shear is for cutting the front-edge of a coil when feeding this in, or when interrupting its processing; or for producing sheets with the line.

The scrap choppers allow an easier handling of the waste.

The stacking table is also used for supporting the material when this is taken over the loop pit into the strip tension unit and, further onto the mandrel of recoiler.
As soon as the line is ready to start slitting, the table is taken to aside of loop pit and the material is left hanging free allowing "flexible" control of loop.
When blanking/multi-blanking, the sheets are collected by the stacking table which automatically goes down according to the height of bundle.

The strip tension unit holds the strips tight during recoiling, so that each of the narrow coils gets properly tightened.
