Specification of the machine

We are speaking about the specialized single-purpose rolling line for manufacture of one horizontal external louver type. This line can process the steel sheet of max. 0.5 mm thickness and aluminum sheet of max. 0.7 mm thickness.

The rolling line consists of the 3 main assemblies:

The first part is created by the active unwinding unit with ultrasound sensor, regulating the unwinding speed. Roll of material with the central screw is fixed on the unwinding unit.

The second part is represented by the rolling line itself: stands with rolling wheels are fixed on the machine stand; the rolling wheels are manufactured by a special technology guaranteeing their long service life. The material passes through the rolling wheels, where it is converted to the shape and dimension requested by the customer. The unit also comprises the straightening head, eliminating minor vertical and horizontal deformations which can appear on the plate during rolling. The rolling line also comprises individual cutting and punching tools.

The third unit is represented by the threading and/or stacking unit. When the material is shaped, when all holes are punched and when the plate is cut to the necessary length, the plate is moved by the next plate towards the threading unit, directly between the textile ladder. This unit can is applicable only for the plates of the "C" and "Flach" type.

In case of the "Z" type the stacking unit is used; it enables to stack the rolled plates to the so called packets. When rolling the "Z" type plates, the following operations are carried out: sealing rubber rolling, cutting and flanging of the hole for the guide textile band, punching of the hole for the side guide pin, fixing of hooks and cutting off to the requested length as the last operation.

When rolling the "C" and "Flach" type plates, the following operations are carried out: cutting and flanging of the hole for the guide textile band, punching of the hole for the side guide pin and cutting off to the requested length.

Operation is done by the rotary panel with the touch display placed directly above the rolling line. The rolling line can be connected to the local network, using another PC. Dimensions of individual orders can then be sent from the information system of the company. In case of certain software failures the rolling line will be connected to internet and our company will remove them.

Great advantage and plus of this rolling line: nearly all operations are carried out directly on the machine and the rolled plate need not be loaded and fed into other tools and assemblies.
