1. Simple and quick seaming
Time-limited stoppages demand quick and easy seaming of dryer screens. The installation aids facilitate the closing procedure. Today there are various different techniques employing zip fasteners for a seam to be closed in just a few minutes. Ease of closure of the seam depends greatly on the particular design of the screen. There are clear differences in the fitting procedure between spiral screens and woven screens. Once the seam is closed, it must be possible to remove the closing aids easily and simply.
2. No seam mark or wear
Studies have shown that one reason why woven dryer screens are changed frequently, 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. spiral screens rule out any risk of seam marking and wear.
3. Optimum dimensional stability (crossmachine stability)
Woven fabrics 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. This property does not apply to non-woven systems, because the manufacturing process differs completely. |

4. The Permeability
We may insert the lines into the spiral loop to low down the permeability .The resulting differences in permeability influence the drying procedure. |

5. Maximum length 150m
The spiral belt also can be used in the following areas: Food, farming and agriculture Mining and mineral processing Chemical, textile. |
