Possible Tension values for SEFAR® PET high-modulus mesh Headquarters mm* N/cm 0.553 50 0.613 45 0.691 80 70 70 40 0.912 35 30 70 70 64 64 55 64 55 64 55 64 55 48 20 1.750 15 2.455 10 40 40 40 25 1.340 48 48 70 34 40 34 34 34 31 34 31 31 31 32 43 45 48 51 54 61 64 68 73 The stated values are in [N/cm] according to DIN 16611 (screen printing standard) and measured using SEFAR® Tensocheck 100. The above values refer to tensions measured after stretching only (before gluing to the frame). These values are valid for dimensions of 1x1m. Larger formats will show a reduction of approx 4% every 0,5 m of additional shank length. Tensioning system requirements In view to obtain the above values, the performance of your tensioning system should be: –Stretching clamps SEFAR® 2, SEFAR® 3A or any other system that guarantees even and balanced tension. –A mesh clamping system that does not allow the mesh to slip, even under high tensions. It should be regularly cleaned and exempted of contaminants such as oil and dirt. –Tensioning clamps should be regularly checked in view to avoid sharp edges which could damage the mesh. –High humidity and high temperature could have influences on stretching performances. This may lead to difficulties during the stretching process. 31 34 31 *Protec STG 75 NA 4PD01081 EN 08/2012 55 48 40 55 1.086 Sefar AG Hinterbissaustrasse 12 9410 Heiden Switzerland Phone +41 71 898 57 00 Fax +41 71 898 57 21 printing@sefar.com www.sefar.com Nominal thread diametre µm 70 80 80 70 0.786 80 27 27 27 77 81 90 95 100 110 120 130 140 150 165 180 190 mesh-count/cm Stretching process / Relaxation: Loss of tension after gluing process Tensioning process lasts up to 3 minutes until the desirable tension is achieved.
