ABSTRACT:
A pull wheel for a form, fill and seal pouch packaging machine has a hub that includes an axially extending central bore and a circumferentially extending peripheral surface that is located radially outwardly from the bore. First and second circumferentially extending flanges are formed integral with and extend radially outwardly from the peripheral surface of the hub. The first and second flanges are axially spaced apart one from the other on the peripheral surface of the hub forming a groove between them. An integrally formed, annular shaped elastomeric body is located radially outwardly from the hub in part within the groove and in further part over and radially outwardly displaced from the first and second flanges such that the periphery of the elastomeric body is displaced radially outwardly from the periphery of the flanges.
