The line is intended for profiling of open U/UD and closed C/CD profiles according to the Knauf classification from thin-sheet galvanized steel 0,55 ... 0,60 mm of thickness. The excellence of final products is ensured with automatic control system and monitoring of master schedule exactitude.

The line consists from two-console non-drive uncoiling device, on mandrels symmetrically located on one axis from two parties of cantilever of which the rolls of measuring pre-form - strips fasten. Second number in a line is the rolling mill with profiling fitting-out, two autonomously working independent from each other strands of which allow to make simultaneously two types of a profile - CD/UD or C/U. Moreover, the mill for production of C/U profiles is delivered with the additional instrument intended for fast re-fitting to production of other standard C/U profile. Additionally, the mill can be universal, in this case one strand makes the nomenclature U/UD of profiles, and second - C/CD. Thus, the shift from manufacturing of one profile on another is carried out with the standard delivery package of the instrument, which provides re-fitting with other things being equal (the professionalism of the attendants etc.) in one hour. Such opportunity lowers the investments in the equipment and reduces the manufacture areas.

The device with a cuneiform knife and pneumatic drive is applied for cutting of a rolled profile, which provides necessary quick action and striking force. Such mechanism operates in profile of each independent strand and is installed on the welded cradle of the rolling mill.

The management of a line is carried out on-line from the board (one on each strand), which opportunities allow smoothly adjusting rolling speed, amount and length of produced profiles. 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 profile ? 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.

The feedback "the gauge of a loop - control system - frictional pair", which is necessary for adjusting uncoiling speed of a roll and working speed of profiling is provided with any of the above of control systems.

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.

The line of UD profile production can be willingly completed with rotor chopping press for piercing of holes of an equal diameter in pre-form. It is installed on the welded cradle of the rolling mill before the first stand with profiling instrument.

The line of U profile production is willingly completed with the carving device for making shaped "butterfly" holes, which cuts simultaneously in three sequentially located points on one axis on a course of pre-form movement. The drive of downing of puncheon is pneumatic and is in a circuit of influence of control system. At such variant of the complete set of a line it is urgently recommended to complete a line by operating console "Elite", the exactitude of cutting of a profile in such case is (+2) mm that cannot be reached at use of control systems of lower level.
