Ease of closure of the seam depends greatly on the particular design of the polyester screen. There are clear differences in the fitting procedure between polyester spiral screens and woven screens. Once the seam is closed during using, it must be possible to remove the closing aids easily and simply.

No seam mark or wear Studies have shown that one reason why polyester dryer screens are changed frequently.Polyester spiral screens rule out any risk of seam marking and wear, as there is no seam used in the paper machine.It is wear in the seam area and in the seam itself. Damage and wear in the seam area may cause marking in the paper, especially in the first drying groups , also originating from differing permeability in the seam area.

Woven fabrics product by our company may be distorted in the weaving process already (mesh distortion from fabric centre to the edges). In woven dryer screens this is noticeably in the "lead" when installing the screen during the drying process. This property does not apply to non-woven systems, because the manufacturing process of different products has differs completely.
