Web Material Advancement Arrangement With An Entry Drive System In A Packaging Machine

A web material advancement arrangement for a packaging machine acting on a web, wherein the web material advancement arrangement defines an upstream end in the downstream end, comprising:

• a pair of endless spaced-apart web engagement members, each of which is configured to engage the web adjacent one of a pair of opposite edges defined by the web;
• a pair of rotatable drive members located at the upstream end of the machine, wherein each rotatable drive member is engaged with one of the endless web engagement members;
• and
• a drive system for imparting rotation to the pair of rotatable drive members, wherein the drive system comprises a motor having an output, a rotatable input member to which each of the pair of rotatable drive members is secured, and a drive arrangement between the motor output and the rotatable input member, wherein operation of the motor causes rotation of the motor output and rotation of the pair of rotatable drive members through the drive arrangement so that the rotatable drive members are driven together in response to operation of the motor.
