Is this a packaging box machine?
No. The BK series stretches canvas onto wood frames. It is kept separate from our case-making and collapsible-box products.

Where it fits
Automate canvas-to-frame stretching.
The BK series is for canvas frame production, not rigid-box or hardcover case making. The supplied 2026 catalogue describes automatic feeding, visual robotic positioning, canvas stretching and nailing to the wooden frame.
Selection starts with outer frame dimensions, wood-frame thickness, canvas type, edge allowance and how the finished piece should be fastened. The larger BK-800 increases maximum format but has a larger footprint.
