The G-STRETCH 201 is a rugged duplex stretching clamp. The wider G-STRETCH 201 clamp allows for the use of fewer clamps on stretch devices, making for a more efficient, optimized, stretching process.
The ergonomic structure of the G-STRETCH 201 clamps allows for easy opening and closing. Additionally, due to the wide opening of the upper stretching beam and the mesh insert edge, the mesh can be inserted rapidly and in true alignment with the thread. The lower half of the clamp remains static while the upper part effectively stretches the mesh without slipping.
The G-STRETCH 201 can be easily repositioned on Grünig stretching devices. This allows it to easily compensate for high extension of the mesh, in either weft or warp direction, when the tension is increased.
Features
- Automatic mechanical amplification of grip force
- No parts require calibration
- Clamps are integrate with V2A guideway system
- High quality aluminum construction
- Existing stretch devices (H-21, H-24 and H-28) can be retrofitted with G-STRETCH 201 duplex clamps, as well as updated guideways

The G-STRETCH 202 PLUS is a cost-efficient, flexible solution for stretching even large screens. It is a step up from the G-STRETCH 202, featuring increased stretch distance and heavier duty construction.
As a low-cost introduction to automatic stretching, it still features advanced programmable controls allowing for individual adjustment of the stretching force in both the warp and weft directions. In addition, it is inherently a flexible system, and can be expanded to accommodate larger frame sizes with the simple addition of more clamps.
The G-STRETCH 202 PLUS stretching process includes automatic pre-stressing of the screen frame, while the mesh itself is stretched off-contact from the frame. After reaching the preprogrammed tension value, the mesh can be lowered onto the frame with a preset amount of pressure.
Featuring the highest quality materials and engineering, the G-STRETCH 202 PLUS is designed to last. Its ergonomic design and retention arm that protects against clamp rebound in the case of mesh failure make it comfortable and safe to use.

The G-STRETCH 202 is a pneumatic stretching system that represents a cost-efficient first step into professional stretching, enabling a high precision, reproducible process. The G-STRETCH 202 includes a pneumatic two-circuit control panel, and provides automatic pre-bowing of the screen frames as well as simple adjustment of the frame profile height.
The desired stretch strength only needs to be adjusted for the first screen of a series. While the mesh is being stretched, the screen frame is prestressed with the same counter-stretching force. During the stretching process, the mesh is automatically pulled over the frame. Once the stretching process is completed, the mesh can be glued directly onto the frame. In the event of mesh tearing, retaining straps prevent the stretching clamps from bouncing back.
Features
- Modular extension is possible in 10″ (250 mm) increments
- Pneumatic stretching with highest precision
- Automatic pre-bowing of the screen frames
- Simple adjustment of the frame profile height
Product Options
- Version A1
- With the addition of a manual control console, the stretching values for both axes can be programmed independently from each other. The stretching process is controlled via a central switch.
- Version A2
- In the automatic mode, the system offers you 30 total freely programmable programs. Upon starting the machine, the mesh is stretched in a fully automatic manner.
- Option Z250
- The system can be enlarged as required, in increments of 250 mm, by the addition of stretching clamps.

The G-STRETCH 215 is an efficient and user-friendly pneumatic stretching machine. The mesh is automatically stretched by means of pneumatic stretching clamps.
The simple and easy-to-use control module contains three separate circuits regulating the X, Y and Z axes. This allows for individual adjustment of the stretching power and speed. Additionally, the stretching power needs only to be adjusted for the first screen of a series. The clamps themselves are actuated by means of two manual switches, one controlling the X/Y axes (mesh tension), and the second for the Z axis (frame contact pressure).
The G-STRETCH 215 can be adjusted in seconds to a range of screen sizes, from large to very small.

The NBC Precision Stretcher is a pneumatic stretching machine developed by NBC in response to customer demands for higher stretching tension. A high end precision device, it features many sophisticated controls not found on conventional stretching equipment.
It also employs techniques that are counter-intuitive to traditional stretching in order to tension extremely low elongation meshes such as V-SCREEN. Designed for ease of use, the NBC Precision Stretcher is a stretching device that allows anyone to stretch V-SCREEN to very high tensions with little training.
The real ground breaking feature of the Precision Stretcher is its diagonal stretching. Adding tension in the corners is counter to traditional stretching methods, as most stretching equipment adds slack in the corners to avoid tearing the mesh during stretching. However, this conventional approach creates distortion in the corners of the mesh. The Precision Stretcher’s novel approach allows for uniform tensioning even in the corners, every time.

The Newman Roller Master Series of pneumatic stretching devices is designed to quickly and easily stretch Newman Roller Frames.
Newman Roller Master stretching devices feature a flat and level table surface that, combined with the precise pneumatic actuation, enables rapid mesh tensioning and stabilization, along with more uniform screen tension.
The 4-way simultaneous stretching enabled by these devices, combined with a 3 minute holding stress, is equivalent to approximately 7 to 10 retensionings. Meanwhile, retensioning mesh with a Roller Master device after the first print run and reclaiming, combined with a 1 minute holding stress, is equivalent to approximately 3 to 4 retensionings.
Additionally, PB models are expandable for different frame sizes.
Features
- Produces at least 3 times as many screens per hour as manual stretching
- Requires less physical effort than manual stretching
- Requires less skill on the part of the operator, and has a simple learning curve
