Underpinners - Frame Assembly Machines

Semi-Automatic | Pneumatic Underpinner

The U-400S has been designed for ease of operation and is particularly well suited for joining frames up to 80mm in width.

Supplied with a tilting floor stand, the machine can be operated from the front or back and has a three stage pneumatic foot pedal that activates the Horizontal Clamp and Vertical Clamp securing moulding during the joining process.

After the framer sets the two position stops for measuring the max distance between strokes, a hand lever is then used to position and actuate V-Nail driver inserting V-Nails anywhere along the pre-set stroke distance.
