For laminated plates production with a polyurethane core there are used coated sheet metal plates bought in circles because the production of plates is continuous and as far as possible uninterrupted. The length of a a rolled sheet metal plate on a circle often exceeds 1 km and frequently it happens that the sheet metal plate has some deviations in the roll. Unwrappers installed on our first line possess system of sensors which check deviations and if they appear, the distances are corrected so that in the next part of the line other problems wouldn't appear. Such system has a particular meaning for a correct performance of locks that connect plates and consequently - easier instalment of plates on a building site.

Profiling section of the sheet metal plates is located just behind the unwrappers, and its aim is to give an aesthetic look to tin linings and to create an adequate shape of the lock which connects plates. Profiling of tin linings is made by means of profiling rolls which owing to an adequate depth of valleys give already installed wall a harmonious look in light which is reflected. During the process of making profiles in a connective lock, particular attention is paid to its most vital feature: equality of performance. Correctly made connective lock makes the instalment on a building site easier, increases thermoinsulating power and fire-fighting safety of housing.

The most difficult stage during laminated plates production is connection of tin linings with a polyurethane core. To do this and to avoid mistakes in this process, a series of activities have to be done. The polyurethane foam consists of three main components that connect themselves in Foam Portal -at the beginning liquid foam in a few seconds grows and hardens and connects permanently with tin linings. For the process to proceed without troubles the adequately heated sheet metal plate must connect in a specific time with the top of the growing foam. This process is extremely vital and influences further aesthetic and technical properties of a plate. Modern devices used in the processing line allow more detailed control over this process.

It is the heart of the processing line. In it, a series of chemical reactions take place which happen inside the polyurethane core and which influence the thermoinsulating power and durability of plates. Constant temperature on a specific level, the speed of line which passes along the furnace, the time when the plates are inside CONTIMAT furnace provide high quality of laminated plates which are produced.

Electronically controlled band cross-cut saw cuts plates accurate to 1 mm. It is equipped with an additional circular saw which makes so-called lap cuts. Laps on roof plates are used to combine plates when the length of the roof exceeds 16 m.

Just after the laminated plate leaves the Heat Furnace, the core of the plate is still hot and likely to be deformed. To start stacking, one have to make sure that the core of a plate is cool enough to put one plate on the top of the other. Line without such section would definitely decrease the quality of produced plates.

Equipped in the system of pneumatic suction cups the stacker provides placing piles of plates without the need of external help, and in such a way it eliminates any possible occurrence of damages. Additionally, computer controlled sequence of placing plates on the pile, according to requirements of the performer of a building, makes assembly easier and more effective
