NBS®90 Narrow Belt Sorter

Reliable, accurate 65 cpm sortation


TGW’s NBS 90 conveyor employs a series of narrow belts, each with patented individual take-up. High-friction rollers raise to grip and gently divert products at a 90-degree angle right or left, on-the-fly. Continuous contact between belt and product provides maximum tracking accuracy, for optimum sort reliability. The NBS 90 carries products at speeds up to 300 feet per minute and achieves a sort rate of up to 65 cases per minute (single side). 

TGW-Sortation-NBS90-drive-unit-2Diverts in the NBS 90 experience less product tipping and skewing, and overall superior diverting characteristics. Unstable products are successfully diverted with the exclusive limited slip-clutch design that provides a small acceleration ramp for diverting. Energy consumption of the TGW NBS is over 87% less than belt with pop-up wheel sorter with a conventional sorter construction. This energy savings translates into less noise, belt pull, and component wear. Energy usage is 60% less than for conventional sorters. In addition, installation time for NBS sorters is close to half of conventional sorters. NBS diverts are easily repositioned to suit the application or to reconfigure. Belt mistracking is eliminated with the total belt retention system. Maintenance requirements are minimal.
