Why use Roller Frames?

TENSION LOSS after printing is easily controlled. Quickly (30-60 secs.) rotate only one roller to retension and restore your mesh to it's original tension (Newtons) level; increasing your fabric life and gaining control of printing variables.

NO NEED TO STORE FRAMES. Reduce your frames on hand, increase valuable shop space, and library only your film and digital file.

INVEST YOUR MONEY. Like other capital equipment in your shop, STF Frames are a long-term investment engineered to last! In most cases, STF Frames can be combined with lease purchases.

Can be used in industry Standard Stretch Tables

STF Roller Frame Information

While promoting pre-stretched textile frames to our distributors, Sefar has seen shops that use static frames, shops that use roller frames and shops that use both. To balance our Textile Frame program, and to give our distributors another sales tool, we have developed the STF (Self Tensioning Frame) Roller Frame. Originally
targeted for the textile segment, the STF Roller Frame can be used by any market segment that can utilize a roller frame.

STF Roller Frames are available in two roller diameters. A 1.4" diameter roller is designed for manual and automatic textile presses, and a 1.6" diameter roller is designed for automatic textile presses and medium format graphic printing. The textile-standard sizes for STF Roller Frames are 18x20 ID, 23x26 OD, 23x28 OD, 23x31 OD and 25x36 OD. The 18x20 size through 23x31 size in the 1.4" diameter roller are also available with a square bar on one side to accommodate back clamping manual presses (see photo below left). Other diameters are currently being developed for larger formats over 50".

Each STF Roller Frame, textile-standard size, is packaged in a box with all the necessary hardware (see above). The hardware consists of locking strips, bolts, washers and corners. Unlike other roller frames on the market, the corners of the STF Roller Frame are preassembled on the long rollers, and the short rollers have the bolts and washers installed. All bolts are pre-lubricated with anti-seize to minimize assembly time of the STF Roller Frame. In addition, locking-strips are pre-cut and inserted in each roller/square bar.

The design of the STF Roller Frame allows the frame to coexist with other models of single locking-strip roller frames, currently on the market. The STF Roller Frame also utilizes the same roller frame tools and stretching systems that are currently in shops today. Conversely, the STF locking strips, Torque Wrench and Wrench will also work with existing single-locking strip roller frames. Here are some additional STF Roller Frame features that add value to the frames:

• Encapsulated end caps do not allow water to enter the cavity of the frame through the bolt.

• Robust cast corners and end caps are the same material and quality that is used in high end pneumatic tools.

• Roller wall thickness of 0.080" helps resist frame deflection under tension.

• Stainless steel bolts & washers resist corrosion to give years of service.
