Two cable tray roll forming lines have finished assembly in our workshop and are ready to ship to a customer in Kazakhstan. One forms Russian type cable trays. The second forms the matching covers. The interesting part is not the destination, it is the layout: both profiles share one front end.
One front end, two forming sections
The shared equipment is one uncoiler, one leveler, one servo feeder, one punch press and one controller. Coil is levelled to remove coil set, the servo feeder measures each pitch into the press, and the press cuts the ventilation and fixing holes to the tray drawing. One controller holds the punch pitch, feed length and cut length recipes for both profiles, so a drawing change is made once.
After the press, the lines are independent. Each has its own roll forming part, hydraulic cutting unit, end expanding unit and hydraulic station. The end expanding unit flares the profile ends so two lengths nest together at the joint. Site assembly is faster, the joint line stays aligned, and cover ends match the trays they close.
Side shifting mills and plug-and-shift wiring
Both roll forming parts sit on a lateral traverse. The operator shifts the active mill until its entry guides line up with the shared feeder, while the idle mill parks beside the line. Every control cable ends in a keyed aviation style quick-connect plug at the shared controller. Changeover takes five steps: run out the coil and clear the strip, unplug the active section's connectors, traverse the mills, reconnect the keyed plugs and select the recipe, then thread the strip and check the first part. No rewiring, no electrician on standby.
There is one honest limit: one front end feeds one mill at a time. This layout suits a plant that needs two profiles now and expects the second to grow. It does not suit a plant that must run both on every shift. Sharing the uncoiler, leveler, feeder, press and controller removes the largest block of duplicated cost, and one strip entry means one coil handling area for both forming sections.
Built for the Kazakhstan drawing set
Russian type trays follow the GOST based drawing conventions used across the CIS region. Section, perforation pattern and cover lip come from the project drawing. The cover is a formed profile with its own tooling, not a press brake accessory, which keeps lip geometry and springback under control. Tooling is built to that drawing and factory acceptance runs on the customer's coil.
Believe Industry has built custom roll forming lines since 2005, with 80+ engineers, machines delivered to 50+ countries, and ISO 9001 and CE certification.
