With the pleater 91 XPR we supply a couple of marking rollers with the pleat dimension (height) suggested by the Customer. Each additional pleat height requires a different couple of rollers.
Couple of rollers with multiple engraving blades to compose a compact module.
A series of alternate blades carries out the pleating groove at a constant distance on the media.
The sectors between the blades can be smooth (smooth marking rollers) or tool-worked to generate on the dragged media a series of reliefs, so to keep a safe distance between the media faces thus allowing an easier passage of the fluid to be filtered (marking rollers with embossing)
In the marking rollers with pleat-lock, the ridge of the engraving blade is interrupted at constant pitch by a flat relief.
This generates short sections with a lightly wider pleat along the pleated ridge, so to avoid that the media faces close one on the other.
