  1. An Introduction To: Orbital Head Technology

  2. History of the Orbital Head • Texwrap started development of the servo driven orbital head in 1998. • By 2000 the design was perfected and fully tested. • The model “146” wrapper was the first wrapper to utilize the orbital head. • Texwrap received patent# 6,854,242 in February, 2005. • The first146 wrappers are still running today, with over 500,000,000 cycles logged.

  3. What so different about the orbital head compared to other cross seal types? • Watch the orbital head in action • The sealing jaw is held in the vertical position • Observe the opening height of the jaws • Notice how smooth the motion is at high speeds.

  4. The Orbital Seal Head is different from Box Motion Seal Heads because: • The Orbital Seal Head does not have to come to a complete stop when cycling. This drastically reduces stress on the components. • The Orbital Seal Head uses inertia to its advantage, it does not fight against it every cycle like a reciprocating Box Motion Seal Head. • The Orbital Seal Head will cycle at much higher rates! At 200 packages per minute the Orbital Seal Head is exposed to very minimal stresses. A Box Motion Seal Head running at this speed would fail in a very short time due to the repeated high stresses resulting from reciprocating motion. • The Texwrap Orbital Seal Head will run at these high rates for the life of the machine!

  5. The Orbital Seal Head is different from Rotary Seal Head machines because: • The Orbital Seal Head knife and cushion maintain vertical orientation during the entire seal cycle. Vertical orientation allows for reduced cutoff lengths and increased film savings. • Shrink films prefer a vertical sealing motion rather than a sweep sealing motion like rotary seal heads. • The Orbital Seal Head geometry accepts a much taller package. • The Orbital Seal Head allows for complete control of film relaxation on the leading and trailing edge of the product. Film relaxation is critical for strong seals in shrink film. • The Orbital Seal Head knife and cushion are optimized for shrink films. Rotary seal head machines are designed for hard (polypropylene based) films.

  6. What does it look like inside?

  7. Inside the gear head • Hardened gears for lifetime reliability. • High load needle style bearings. • Designed safety factor over 400% for all components.

  8. What about the belts that drive the gear heads? • Each gear head belt is designed with a safety factor over 1,000%! • Belts are designed for infinite life! • There has never been a belt failure since the inception of this design.

  9. Texwrap Orbital Seal Head Packaging Machines. • Made In USA • Continuous Duty High Speed Packaging • Low cost of ownership • Domestic parts availability • Proven track record in demanding 24/7 environments • Speed, Flexibility, Dependability
