Titan TN-9C High-Speed Bag Closing Machine

High-Speed Industrial Bag Closing for Demanding Production Lines

The Titan TN-9C is a high-speed, single-needle industrial bag closing machine engineered for continuous production environments where speed, consistency, and reliability are essential.

Designed specifically for closing filled bags and sacks, the TN-9C produces a strong two-thread 401 chainstitch at speeds of up to 2,700 stitches per minute. Its robust construction, automatic lubrication system, and integrated pneumatic cutting system make it an excellent choice for packaging operations handling everything from agricultural products and animal feed to chemicals, minerals, food products, and other bulk materials.

Whether installed as part of a dedicated sewing station or integrated into a complete automated bagging and conveyor line, the TN-9C provides the performance required for dependable, high-volume bag closing.

Built for Continuous Production

Production bag closing places very different demands on a sewing machine than conventional textile sewing. The TN-9C is designed specifically for this environment.

With sewing speeds reaching 2,700 SPM, the machine can keep pace with high-output filling and packaging operations while producing a secure, consistent closure. The bottom-feed system moves the bag smoothly through the sewing area, while an adjustable stitch length allows the machine to accommodate different bag constructions and production requirements.

The TN-9C can be vertically mounted on a pedestal and combined with an infeed system and conveyor, making it well suited to both semi-automatic and fully integrated packaging lines.

Automatic Thread & Crepe Tape Cutting

For applications using crepe tape reinforcement, the TN-9C incorporates a pneumatically operated cutter designed to cut the sewing thread and crepe tape automatically at the completion of the seam.

This eliminates a separate manual cutting operation and helps create a cleaner, more efficient production process, particularly in repetitive high-volume bag closing applications.

Automatic Lubrication for Industrial Reliability

High-speed sewing requires reliable lubrication.

The TN-9C uses an automatic oil-bath lubrication system to continuously lubricate critical internal components during operation. The design also incorporates dust-protection measures around key moving components, helping reduce wear in the dusty environments commonly found in grain, feed, fertilizer, mineral, and other bulk-product packaging facilities.

The result is a machine designed for extended production use with reduced routine maintenance requirements.

Strong 401 Two-Thread Chainstitch

The TN-9C produces a single-needle, two-thread Type 401 chainstitch, one of the most widely used stitch formations for industrial bag closing.

The chainstitch provides a strong, flexible closure while allowing filled bags to move efficiently through a production line. An adjustable stitch length of approximately 7–10.5 mm, with 10 mm as the standard setting, allows the closure to be optimized for different bag materials and operating requirements.

Suitable for a Wide Range of Bag Materials

The Titan TN-9C is designed for closing filled bags manufactured from materials including:

Kraft and paper bags

Woven polypropylene bags

Textile and cloth bags

Jute bags and sacks

Other common industrial packaging materials

This versatility makes the TN-9C suitable for packaging operations throughout the agricultural, food processing, feed, fertilizer, chemical, mineral, and general industrial sectors.

Technical Specifications

Designed for Complete Bag Closing Systems

The TN-9C can operate as the sewing head within a larger bag-closing system incorporating a height-adjustable pedestal, bag infeed equipment, crepe tape system, and conveyor.

This makes the TN-9C particularly well suited for facilities looking to move beyond manually operated portable bag closers and establish a dedicated production bag-closing station or automated packaging line.

For higher-volume applications, automated systems based around this machine platform can also incorporate photo-sensor start/stop control, powered conveyors, bag-top preparation systems, and automatic label or tag placement equipment.

Ideal Applications

The Titan TN-9C is an excellent choice for closing bags containing:

Agricultural products • Grain • Seed • Animal feed • Flour • Fertilizer • Salt • Sugar • Minerals • Chemicals • Food ingredients • Industrial bulk products

Its combination of high sewing speed, automatic lubrication, pneumatic cutting, and production-line compatibility makes it particularly well suited to facilities where filled bags need to be closed quickly and consistently throughout the working day.
