Pester's overwrapper for luxury products is efficient, too

Consumers' expectations for high end cosmetics and pharmaceuticals call for the use of premium cartons and perfect overwraps.  Full overwrapping combines an esthetic quality, protection, plus the ability to display product and regulatory information without detracting from the premium look of the carton once unwrapped.

Pester Pac's new PEWO-fold C120 meets this requirement hands-down. With an output rate of 120 cartons per minute regardless of carton size and changeovers in only 5 to 10 minutes with minimal change parts, luxury packaging becomes very practical.

Willi Rassl, product and development manager for full overwrappers, explains the role of ELAU automation technology in delivering gentle, precise handling at high speed.  Even premium cartons with sensitive, glossy finishes can be wrapped without scratching or scuffing.

“The unique selling point…is the gentle way in which products are fed in despite the high speed….Altogether, 12 ELAU servo motors are responsible for a continuous, gentle product flow on a single level,” explains Rassl.

Through constant tensioning of the film, The PEWO-fold C120 creates a tight, smooth overwrapping. Precise temperature control means consistent surface finish and pinpoint sealing accuracy.  

Product-specific orientation enables longitudinal or transverse wrapping for added flexibility in package design.  So does the fast and easy format change capability and constant throughput rate.

A fully automatic film splicer, a wear-free transport system (excluding tongs and vacuum belts) and a special film cutter assure maximum availability.

The ELAU automation system's advanced technology makes it easy to program and easy to select cycle rates and formats.  Rassl believes it to be the first continuous motion machine in its category.

The machine concept is based on ELAU's master-slave servo architecture to provide a modular building-block design that integrates advanced motions through simplified drivetrains such as crank mechanisms.  The ELAU technology is highly dynamic, minimizing footprint, while the cantilever design allows easy service access to drive components.

The entire machine was developed in just 6 months using ELAU's software development environment from the outset of project planning.  The result was a simulation model that was used to realistically test structural parameters and substantially simplified tasks such as drive sizing and determined machine geometry.

“The result is a clearly structured, very customer-oriented machine design that went from draft to serial production within only six months,” reports Torsten Gietenbruch, responsible for the software engineering.
