In a league of its own: High-speed valve bottomer ad*starKON SX

Combining outstanding production speed, high-precision bottom closure and superfast format change, the latest model in the Starlinger AD*STAR conversion line series gives converters a technological head-start in poly-woven block bottom sack production.

The keyword is efficiency: Increased production efficiency translates into increased profits. In converting, high production efficiency means quick material roll change and format change, little machine downtime and a low waste rate. All these criteria have been taken into account in the development of the new ad*starKON SX to create a highly efficient, fast and reliable conversion line for the patented AD*STAR sacks made of coated polypropylene tape fabric. Designed for the economic production of standard, open mouth, 2-ply, pocket valve and BOPP laminated AD*STAR sacks the conversion line runs at a production speed of up to 85 sacks/minute, with a pin-free continuous sack transport system and highly precise bottom forming system ensuring reliable bottom and top closure without harming the fabric.

Even if the width of the tape fabric on a roll used for sack production varies, the ad*starKON SX will be able to convert it into perfect block bottom valve sacks. An integrated fabric width monitoring system continuously checks the fabric width and automatically compensates width variations, ensuring constant high-quality bottom geometry. This not only avoids unnecessary machine stops but also reduces the number of rejects significantly. And changing the sack format is now easier than ever: It is done automatically by key press on the main control panel.
