DESCRIPTION

• Frame made up of 4 independent metal parts. Each of these parts must be fitted on each side of the frame and the mesh, surrounding its entire perimeter
• Handwheel to stretch the mesh towards the outside of the frame
• Mechanical stretching allows you to tighten the entire surface of the mesh simultaneously and uniformly. This makes it easier to adhere the mesh to the frame by using fast-drying, solvent-resistant adhesives
• Easy to install, use and carry

THINGS TO KEEP IN MIND

• The mesh must be larger than the frame, at least 10 cm per side
• By combining two of these machines, you will have 8 parts to stretch the mesh, 2 per side. This allows you to stretch meshes of up to 1.20 cm
• We recommend the use of a tension meter for more precise results. It has a measuring range of 7-50 newtons
• It is not recommended to use staples to fix the mesh to the wooden frame. High tension may cause tearing when piercing the fabric with staples

WHAT DOES THE MACHINE INCLUDE?

MACHINE COMPONENTS FOR EACH METAL PART

• 3 clamps: hold the bars and keep them steady, at the same height as the base
• 1 bar with 2 platens: each bar is made up of 2 platens to hold the mesh. They must be placed inside the clamps, above and below the mesh like a sandwich. The lower bar is fixed, while the other can be removed. The part of the bar that touches the mesh is made of corrugated rubber for a better grip
• 3 adjustment knobs: to keep the mesh fixed inside the clamps while stretching the screen. They have a pressure-resistant conical washer at the lower end, which prevents damage to the contact surface of the bolt (upper bar)
• 1 base serves as a support and is perpendicular to the bars. It has 2 slots allowing the bars to slide. Sliding it forward or backwards will help adjust the structure to the frame. When stretching, the frame sits between the bars and a metal plate that works as a stopper
• 1 adjustment wheel: allows you to move the bar back and forth through the slots. The handwheel rotates and moves along a metal bolt. This bolt has 3 lock washers to prevent any damage due to pressure. The washers remain between the base and the handle when they reach the stop

INSTALLATION AND OPERATING INSTRUCTIONS

ASSEMBLING EACH PART OF THE MACHINE

To assemble each metal part you need 1 base, 1 bar with 2 platens, 3 clamps, 3 adjustment bolts and 1 adjustment wheel.

• Place the mesh clamp on the base. The central adjustment bolt must be positioned in the centre of the bar
• Fix the bars to the central clamp by adjusting the washers and the nuts. Use a 14” spanner to do this
• Place the plastic handle on the adjusting wheel and fasten the wheel with the nut

HOW TO USE THE SCREEN STRETCHING MACHINE FOR SCREEN PRINTING FRAMES?

• Place the parts of the machine on a flat surface suitable for this task
• The frame must have a thickness no greater than 5.5 cm and a maximum outer diameter of 60 x 60 cm. The size of the mesh must be larger than the frame, minimum 10 cm per side
• Put on each side of the frame one of the 4 machine parts
• Insert the frame into each base, with the front side facing upwards. The frame profile should be placed over the base slots, between the plate acting as a stopper and the bars
• Sandwich the mesh between the bars
• Tighten the bolts so that the mesh is securely held by the bars. Make sure that each bar has the same amount of mesh
• Turn the wheels until you reach the desired tension
• Apply a layer of adhesive on the mesh and the frame, following the adhesive’s instructions
• Wait for the adhesive to set completely, then remove the parts of the stretcher
• Trim off the excess mesh
