A continuous sandwich panel line needs to run production non-stop even during a coil change. If a continuous line stops during production, it can result in several meters of scrap panel and wasted time. By utilizing a Bradbury automated coil joining unit and four uncoilers, a Bradbury continuous insulated metal panel line automatically joins coils together for uninterrupted manufacturing of panels.
How does the coil joining process work? As the coil in process is depleted, the new coil is fed directly to the trail end of the leading coil. Positioned by coated rolls, the material is fed through a shearing station which generates straight ends on both strips. The strips continue through the joining unit, end to end, where they are connected by the automated adhesive process. The strip accumulating station allows the line to continue while the joining station is activated.
What advantage does this system bring to your production? The automated joining unit allows you to safely change the color of your panel on the fly or simply add another coil without stopping the line. Our smart controls know where to cut your panel to remove the adhesive seam with a minimal amount of scrap. The joining unit is a stand-alone system and can be installed into any production line.
