Linia CZS Zeman

The line was produced in 2010. Full modernization took place in 2020.

ZEMAN CZS LINE – SPECIFICATIONS
The fully automatic “PURLIN” line, ZEMAN’s flagship product, is designed for the production of open, cold-formed profiles such as C-, Z-, and Sigma-profiles in a variety of widths and shapes. This is enabled by fully automatic adjustment of the profile rollers. As input material, coils up to 750 mm in width and sheets with a thickness between 1.25 mm and 3 mm in grade S-390 and lower can be processed. The machine is designed to produce components up to 15 meters in length. The width of the specially hardened profile rollers can be continuously adjusted via dedicated software. A fully integrated punching unit creates all types of fastening holes. The entire process runs continuously, meaning the material does not stop for individual operations such as punching or cross-cutting. To ensure high production efficiency, the line speed is optimized dynamically. The machine automatically decelerates and accelerates without operator intervention.

A coil decoiler with a maximum working load of 15 tonnes is mounted on a trolley and allows precise centering of the strip before it enters the straightener.

The straightener, in combination with a camber correction system, straightens the material, ensures the required flatness of the sheet, and reduces the camber on the conveyor belt.

2. Punching section
This section features five double, “flying” punching portals which can be fitted with 20 small (up to 40 mm) or 10 large (up to 100 mm) tools (punches and dies) for punching fastening holes.

A combination of these tools is also possible.

3. Pre-cut shear
A “flying” shear is used for pre-cutting holes for the cutting shear. This process ensures material continuity and results in a more precise profile shape, especially at the beginning and end. It uses an adaptive guillotine that adjusts the width of the punched hole to the width of the strip.

4. Guiding trolley/SIGMA modules
The guiding trolley centers the strip before entering the roll forming machine. It can be interchanged with the module for producing Sigma profiles.
For S+ profiles, the guiding trolley is removed and two Sigma modules are used. These modules position themselves automatically and independently left and right.

6. Rotary cut-off saw
The rotary cut-off saw with hooked knives separates the finished profile from the material strip. It uses the holes made by the pre-cut shear. This is a “flying” cut-off saw, so the strip remains in motion during cutting. Depending on the desired profile, an appropriately aligned cutting cassette is used.

7. Receiving table
The receiving table serves for the automatic discharge of the finished profiles from the roller conveyor. The elements are subsequently manually grouped into a bundle. The design allows for easy bundling of the package. The table is dimensioned for the receipt of profiles up to 15 meters in length and enables access by forklift or overhead crane to pick up the profile bundle.
