Packaging machine has parallel transport chains for feeding continuous packaging material web passed around chain wheels coupled for synchronous rotation

摘要

The packaging machine has a frame with 2 opposoing side frame elements and a transport device for gripping and transporting a packaging material web (7), provided by 2 parallel transport chains (5,6) engaging the material web side edges, passed around respective chain wheels (10,11), which are coupled together for synchronous rotation via a shaft (12) with high torsional rigidity.
