The line is intended for manufacturing of metal siding such as "herringbone unary", "herringbone double", "ship lath" from a sheet of galvanized steel of 0,3 ... 0,6 mm width or metal with varnish-paint decorative defending cover. The excellence of final products is ensured with automatic control system and monitoring of master schedule exactitude.

The line consists of the non-drive cantilever uncoiling device, rolling mill with the recharging device, cutting device with figurate knifes, receiving table and operating console.

To a mandrel of a non-drive uncoiling device the roll of measuring pre-form fastens, which fixing is made by the hand-operated unclasp mechanism. For the coordination of roll uncoiling speed and working speed of profiling, the construction of the uncoiling device is supplied with a frictional pair, which drive receives a signal through the coupling circuit ? "the gauge of a loop - control system". The rolling mill, which part is the recharging device intended for longitudinal centering of a sheet, consists of the working stands with the profiling instrument. The process of manufacturing of sheets conducts by method of sequential profiling. The design solution of accommodation of shafts with the working instrument allows in a short time to rebuild a line for manufacturing of other type of siding by introduction or deduction from the master schedule of working stands responsible for shaping of a profile section element. For cutting of a rolled sheet the pneumatic cutting device is used, which figurate knifes precisely iterate a relief of cross-section of a metal siding. To exclude the bias of working planes of the rolling mill and guillotine rather one another during adjustment and operation, the body of the guillotine is installed closely and fastens to the welded cradle of the rolling mill.

The management of profiling part of a line is carried out on-line from operating console, which opportunities allow smoothly adjusting rolling speed, amount and length of produced sheets. These opportunities are given by control system "Standard", more capacious system "Elite", which circuitry is constructed on inverter technology, provides smoothly varying execution of commands "start-up", "stop". Thus, the inertness of process is considerably reduced, the exactitude of profiling on length of a sheet is augmented, the wear of the details and mechanisms subjected to abrasion is diminished by several times and term of life of the equipment increases.

The alternate solution of problem of management of a line is the console "Minimum", principle of operating of which is providing of feedback ? "length of a ready siding ? cutting device" - by means of the induction gauge with which the receiving table is equipped. Moreover, the migration of the gauge along a table proportionally reflects on the length of final products.

Receiving table is intended for reception of final products, which length corresponds to length of a table, has an accumulator for temporary warehousing. The construction of the receiving table is designed in view of ergonomics of human operator movements and allows performing the job without special efforts.
