Key Advantages
High-Speed Accuracy: Maintain incredible placement precision even at maximum throughput, hitting speeds up to 35,000 pieces per hour for single 1-inch tabs.
Versatile Tab Placement: Easily configure the machine to meet complex mailing requirements by applying 1, 2, or 3 tabs per piece, accommodating left, right, or flat tab (gate fold) orientations.
Modular Portability: Self-contained controls housed directly within the tabbing head allow operators to seamlessly move and integrate the unit wherever it is needed in the production line without bulky external control cabinets.
Automated Operation: Drastically reduce guesswork and setup times with automated features including automatic backer sensing, digital production counters, and clear error reporting.

Frequently Asked Questions
What tabbing machine runs 35,000 pieces per hour?
The Buskro BK730, which applies 1 to 3 wafer seals per piece at 35,000 pieces per hour with left, right, or flat placement, standalone or inline.
Is the Buskro BK730 USPS and Canada Post compliant?
Yes. It is built to apply wafer seals within the positional tolerances USPS and Canada Post automation requires, which protects automation-rate discounts.
What is the difference between the BK730 and BK730WL?
Tab width. The BK730 applies tabs up to 3 inches, the usual wafer seal size for self-mailers. The BK730WL applies tabs up to 5 inches for packaging, gate folds, and oversized seals. Speed and placement are identical.
Can a tabber run standalone or does it need a full line?
Both. The BK730 has self-contained controls with no external cabinet or PLC, so it runs as a standalone station or drops inline between an inkjet base and a folder or inserter, and moves between lines.
What size wafer seals does USPS require?
1 inch minimum diameter on most folded self-mailers, 1.5 inch on heavier pieces like newsletters and unbound booklets, always non-perforated for automation rates. Foil tabs are not recommended. Mailtech stocks compliant tab rolls locally.
