K1X Jumbo: Built for Heavy-Duty Corrugated Production

Oct 30, 2026 | Alexis Fritkin

When corrugated manufacturers need to produce oversized, heavy-duty boxes, standard converting equipment may not provide the size, strength, or stability the job demands. The K1X Jumbo is designed specifically for large-format corrugated production, giving manufacturers the capacity to handle demanding industrial applications with confidence.

Designed for Jumbo Applications

Built to process large sheets and heavy board grades, the K1X is well suited for manufacturers serving industries that require oversized or high-strength corrugated packaging. Its heavy-duty construction supports consistent production while handling materials up to triple-wall board.

The K1X is available in 2253, 2255, 2653, and 2655 sizes and can operate at speeds of up to 4,800 sheets per hour. This combination of size and production capacity allows manufacturers to take on large-format work without sacrificing efficiency.

More Capabilities in One Production Line

The K1X can be configured as a flexo folder gluer or flexo printer slotter, depending on a plant’s production requirements. Available capabilities include printing, computerized slotting, full-width rotary die cutting, folding and gluing, and optional stitching.

By bringing multiple converting processes together, the K1X can help streamline production and reduce the number of separate machines or handling steps required to complete a box.

Key available features include:

  • Lead-edge feeding
  • Motorized side guides and backstop
  • Vacuum sheet cleaning
  • Motorized board-caliper controls
  • Electronic running registers
  • Touchscreen operator controls
  • Dual slotting sections
  • Computerized slotting-head setup
  • Full-width rotary die cutting
  • Motorized vacuum folding rails
  • Gluing and squaring systems
  • Downstacking
  • Optional stitching capability

Features and configurations may vary by machine model and application.

Built for Strength and Consistency

Large corrugated sheets can be difficult to control as they move through production. Accurate feeding, registration, board handling, and setup become especially important when working with heavier materials and oversized dimensions.

The K1X uses motorized and computerized controls to help operators manage critical machine settings. Servo-controlled registration, motorized adjustments, and touchscreen interfaces support repeatable setup and consistent performance across demanding production runs.

Its heavy-duty components—including chrome-plated shafts and cylinders, pneumatic frame locks, and an available anvil-grinding system—are designed to support the demands of large-format converting.

Expanding Large-Format Capabilities

For box plants looking to expand into jumbo packaging, increase capacity, or replace aging equipment, the K1X offers a flexible production platform built around heavy-duty applications.

With multiple sizes and configurations available, manufacturers can select a solution based on their product mix and production goals. Whether the operation requires a printer slotter, a complete flexo folder gluer, rotary die cutting, or optional stitching, the K1X can be configured to support the work.

More Boxes Every Minute

The K1X Jumbo gives corrugated manufacturers the strength, size, and production capacity needed to compete in the large-format packaging market. It is built to handle demanding materials, consolidate converting processes, and help manufacturers get more from every production minute.

MORE BOXES EVERY MINUTE… PERIOD!
