Straight Shooter B-12 + D-12 Batch / Demand Feeder
Product Details
The Straight Shooter B-12 batch counting feeder + D-12 demand feeder feeds substrate in defined batch counts — used for inserter lines, sortation feeds, and any production workflow that processes mail in discrete batches rather than continuous streams. This video shows the batch feeder in operation.
What this video shows: Substrate loaded into the batch feeder magazine, the feeder presenting defined batch counts to the downstream line, and the workflow that distinguishes batch feeding from continuous feeding. Batch-end signaling for downstream batch-aware stations.
Who runs the Straight Shooter B-12 + D-12: Folder-inserter lines that process mail in defined batches (one insert per batch per envelope). Sortation operations that need batch-discrete feeding for bin-level routing. Pressure-seal operations running batched form jobs. Any production line where batch boundaries matter for downstream routing or counting.
Why batch over continuous feed: Continuous-feed delivers a stream without batch awareness. Batch feed delivers exactly the count needed for each downstream cycle — eliminating mismatched-count errors and supporting batch-aware downstream logic. For inserter and sortation lines, batch feeding is the standard.
Key specs: Straight Shooter B-12 + D-12 batch feeder | Substrate: paper, card stock, mail pieces | Batch count: configurable per job | Throughput: matches downstream line rate | Batch-end signaling for downstream stations
Frequently asked
Can the batch feeder switch between batch and continuous modes?
Configuration is typically batch-or-continuous per job. Switching between modes is a setup change, not an in-job toggle.
How does the feeder know batch counts?
Batch count is set in feeder configuration. The feeder counts pieces and signals batch-end at the configured count, then either pauses for downstream cycle or continues to the next batch.
Is a batch feeder right for high-volume continuous mail?
For continuous high-volume operations without batch boundaries, a continuous feeder (Walco VF, pile feeder) is the right choice. Batch feeders shine where batch boundaries matter to the downstream workflow.
