Roller Master™ Stretching & Retensioning for Newman Roller Frames Patent #5,488,901 #5,913,263 #5,937,953 and Foreign Patents Pending |
Achieve Higher Screen Tensions Faster
"Using the Roller Master, you can tension any size Newman Roller Frame in seconds. We love how easy the Roller MasterTM is to learn and operate, and that it produces a flat screen every time.We're saving substantial time and energy in stretching frames and we have the ability to stretch fabric in all four directions at once. We also get consistent tension from screen to screen by easily pre-determining the air setting."

Tension the mesh quickly (approximately 1 minute) to one of the 3 different choices of tension (see chart below). Hold the tension for approximately 3 minutes and then lock the bolts as normal.
| The
low friction, 4-way simultaneous tensioning on the Newman Roller
Master™ , combined with a 3 minute holding stress, is equivalent
to approx. 7 to 10 retensionings. |
All the latest generations of super high strength filaments prefer to be tensioned and retensioned quickly to high Newton levels.
The following tensioning, retensioning, and printing data is the result of 10 months of intensive research and testing at the Stretch Devices, Inc. technical facility and field test sites. Tests were conducted on the Newman Roller Master™ using Newman Roller Frames. Tensioning and printing tests were conducted using a variety of meshes including Newman Roller Mesh™ , Sefar LE, Saati HT, NBC-EX, and Nitoku SS.
Mesh tensioned on the Newman Roller Master using these procedures increases the rate and level in which the mesh both work-hardens during the initial tensioning and during subsequent retensioning after the 1st and 2nd print runs. Retensionings thereafter will be much less frequently required. A quick check of your screen tension level with your meter should be made after each print run. Generally it should only be necessary to retension your screen if it has lost 2 Newtons or more. This quick procedure will keep your screen as a CONSTANT. The mesh tensioned in this way will exhibit very stable and durable properties.
This method of tensioning allows virgin mesh (new screens) to be far more stable during the first print run. As always, virgin mesh will not be as dimensionally stable as mesh that has been printed with, reclaimed and then retensioned back to the same CONSTANT NEWTON level.TECHNICAL FOOTNOTE: The mesh tensioned in this way will exhibit less overall internal differential stress

You can print at lower tension levels with any of the meshes listed on these charts assuming that in the end, you are satisfied with the print quality and the typically slower print speed. The Newman Roller Mesh has historically shown over the past 8 years, to print the best and the quickest for the 3 tension levels recommended for each mesh. However, many customers have also found their desired results at slightly lower tension levels. The proof is always in the print quality and being able to achieve the fastest and yet comfortable production rates. (Newman Roller Mesh will also print at higher tension levels than those shown.)
To do this, you would start by adjusting the initial tension approximately 5 Newtons lower. This will result in a stabilized tension before the 1st print run of about 5 Newtons lower as well. Over the past 8 years as the filaments have gotten strong; Newman Roller Mesh has been adjusted to provide a slightly larger percent open area. This has been done while still producing an exceptionally strong, durable, and abuse resistant screen printing mesh.
Drop in tension levels depends upon squeegee pressure, ink and chemical types, print run length, off-contact, and image size as a proportion of frame size. Be sure your existing Newman Roller Frame model and mesh brand will allow you to take advantage of this new level of tension technology.
Our testing and printing information shows the testing data at a conservative level. The remaining and new mesh counts will be tested. Call Stretch Devices, Inc. with a specific mesh count and diameter request.
