Narrow Belt Live Roller

Narrow Belt Live Roller Conveyor is a traditional AC powered design with a narrow belt under the rollers that provides roller drive for transportation or accumulation applications. The accumulation version, Narrow Belt Accumulation (NBA), is a key technology in applications like high-speed merging and process buffering to create high-density singulated flow.

Our modern reinvented NBA technology provides the highest levels of throughput, control flexibility, gentle zero pressure product density, durability and reliability and is also available for non-accumulating very high-speed transportation.

Narrow Belt Accumulation Overview

Trew’s Narrow Belt Conveyor Line takes on industry-wide challenges head-on through its innovation and intentional design.

 

Modern re-engineered design delivers operational confidence, throughput, gently zero pressure product handling and reduced maintenance.

Intelligent accumulation conveyor controls are easy to understand and configure enabling gently zero pressure accumulation and high-rate releases to downstream conveyor.

Used to buffer containers, balance workflow between processes, or build up queues for merge and sortation systems, Trew’s Narrow Belt Conveyor Line provides high-density pneumatic minimal pressure accumulation with less product damage and fewer jams. The factory-installed zone control provides field selectable accumulation modes and two release options with high visibility diagnostics and error notifications for faster installation, improved maintenance response time, and improved overall operational performance.

Narrow Belt Conveyor - Transportation

NBT.png

Trew’s Narrow Belt Transportation conveyor allows for a cost effective solution when  accumulation is not required. Because the NBT utilizes similar components from the  Accumulator, upgrading your transportation unit is seemless. This conveyor line ensures  maximized system uptime by taking advantage of industry leading belt retention capabilities.

Narrow Belt Controller

The Narrow Belt Controller provides industry-leading functionality and diagnostic features factory mounted and ready for installation. The pneumatic dual zone controller provides “on conveyor” logic for Standard Singulation, Local Singulation, and Auto-Slug accumulation modes, Slug and Singulation release options, and settings that enable increased efficiency and maximum product density.

 

Each controller provides high-visibility indicators to help maintenance and operations quickly identify accumulation behavior, individual zone health, accumulation network status, and jam conditions. Easy to integrate interface modules allow system-level controls to provide control signals or monitor the status of a zone.
