When installing, do not pull the panels apart or press them together (see figure below).
The lateral expansion (B) of the panels must be taken into account: This spacing can vary depending on the roll former and system used.
Attention
Install only one sheet at a time, set the grip pliers, close the seams and fix the clips afterwards!
Double and angle standing seams can be closed manually using an angle seam closer or mechanically using seaming machines. The following must be observed in particular when closing the seams mechanically.
Before closing the fold mechanically, first tack the fold lightly at intervals of approx. 1 meter with the angle standing seam closer (see figure below).
Fix the tray over the entire length with seam clamps (see Image 1) at a distance of approx. 1.5–2.0 m (see Image 2). Thus both vertical legs will be compressed to 90°.
Seam clamps with plastic jaws (e.g. MASC type SGZS) every 1.5–2.0 m (Fig. 1).
At least 2 seam clamps are required for closing the seam, they will be readjusted during the process. Setting the grip pliers (Image 2).
Before the fold closer is inserted into the fold, the fold must be preworked over a machine length of approx. 35 cm according to the illustrated scheme (see figure above).
Seaming: With coated aluminium coils, little pressure is required from the pushing rollers (as opposed to more brittle, harder materials).
Adjust the pressure on the seaming machine. Lubrication is not necessary. The spacing between the metal sheets is determined by the seaming machine (seaming system) and should be approx. 3-5 mm.
Note
seaming machine adjustment: Care must be taken to ensure that the seamimg machine is equipped with the correct set of rollers to prevent indentation of notches in the profile sheet. A notch in the lateral
profile sheet inevitably means that the sheets will bulge (see manufacturer’s manual). Adjust the fold spacing to the laying temperature: When using a folding machine, too great fold spacing can lead to deformation of the folded edges and thus to dishing up of the sheets. A small spacing prevents lateral expansion.
