The next generation of the Flex Flow Accumulator from Nercon Eng. & Mfg., Inc. provides accumulation essential to the efficiencies of food and consumer goods manufacturing lines. It operates on the concept of an expandable travel path which automatically changes length to match fluctuations in production. The in-line accumulation delivers a more consistent product flow to downstream equipment which in turn increases the operational reliability of these production line machines. An upgraded side transfer feature helps reduce maintenance time due to improved chain take-up that increases life of the chain. The system allows for multiple in-feed and discharge locations.
