  Technical featuresThe principle of H1 technology is the idea that superior web properties can be attained through oblique angled needle penetration. Such penetration is achieved by means of an asymmetrically curved needling zone and straight needle movement.
Advantages- A longer needle path through the web creates better fibre orientation. - Randomisation can be attained far earlier without an increase in draft as a result of fibre reorientation. - By the employment of the H1 technology higher strength, density and delamination values can be reached. - The asymmetric curve of the perforated plate prevents web flutter, while simultaneously providing controlled needling, increased web stability and reduced width shrinkage ApplicationsMachines using H1 technology are mainly employed where web stability, a 1:1 MD/CD ratio and high end product strength are of decisive importance, e.g. for geotextiles, synthetic leather, filters, shoe linings, automotive textiles and papermaker felts. |
