SI 2-Stream Rotary Cutter and “TDT” Tape Delivery Table

The SI 2-Stream Rotary Cutter and the “TDT” Tape Delivery Table are advanced finishing solutions engineered for high-volume direct mail and commercial applications. These systems are designed to streamline the processing of inline folded products and enhance overall productivity, reliability, and product quality.

SI 2-Stream Rotary Cutter

Overview

The SI 2-Stream Rotary Cutter is built to handle two streams of inline folded products side-by-side, enabling the production of up to five around products per stream. It features chip removal capabilities, ensuring clean inline finished products suitable for direct-mail and other commercial uses. The unit operates independently, powered by a servo motor, with its own dedicated software and controls provided by SI.

Standard Basic Features

• Two-stream capability for simultaneous processing.
• Entrance fold hold roller assembly to maintain product alignment.
• Driven textured entrance draw rolls with upper and lower nip wheels for secure feeding.
• Helical gear drive train equipped with anti-backlash gear for precise cut accuracy.
• Knife location arm featuring replaceable locator tips and a safety interlock for operator safety.
• Hard chrome-plated two-around anvil cylinder, super finished for extended cutting surface life.
• 15-gallon temperature-controlled forced oil lubrication system to main bearings, ensuring thermal stabilization.
• Computer-controlled, push-button “on-the-run” knife adjustment for efficient operation.
• Push-through pin capability in the anvil cylinder, supported by pin rods for handling heavy chips.

Additional Standard Basic Features

• Swivel mount information display panel with operational readouts.
• “On-Demand” product length change using the Knife Positioning Program (KPP).
• Five-around capability with a minimum chip size of 0.25” for full web processing.
• Non-contact air chip removal system integrated with a vacuum hood.
• Automatic lubrication system for reduced maintenance.
• Manual machine side lay adjustment of +/- 1” for precise product positioning.

Available Options

• Expanded web width capability for greater flexibility.
• Alternate stream capability to accommodate various production needs.
• Cassette cylinder section for multi-cutoff capability.
• Dedicated cover production components, including 20” wide standard knife blocks and spacers.

“TDT” Tape Delivery Table

Overview

The SI “TDT” Tape Delivery Table is designed for integration with both inline and offline production systems, including cover production applications. Like the rotary cutter, it is independently servo driven with software and controls provided by SI.

This system is engineered to improve finishing operations by reducing jam-ups and unscheduled stops, which are common in other delivery solutions. The result is less spoilage, increased running speeds, and shorter production times on press.

Standard Basic Features

• First-stage fast tape section for precise product gap spacing.
• Common side-lay configuration for both upper and lower fast tapes, ensuring consistent alignment.
• Two-stage wide belt slow down tables for controlled product deceleration.
• Head stop wheels for effective management of shingled products.
• “On-the-fly” manual second-stage height adjustment for operational flexibility.
• Power assist roll back for easy product handling and setup.

Conclusion

The SI 2-Stream Rotary Cutter and “TDT” Tape Delivery Table collectively offer a robust solution for businesses seeking to optimize their finishing operations. With advanced automation, precise control, and flexible configuration options, these systems are well-suited for demanding direct-mail and commercial production environments.
