Abstract
A rollstock support spool supports rollstock formed from a continuous web of bags of non-uniform thickness along their length. The spool has a hollow core and first and second opposed rims. The hollow core has opposed axial ends, an inner peripheral surface defining a tubular opening configured for mounting over a spindle, and an outer peripheral surface configured to support the rollstock. The rims are located at or near the first and second ends of the core, respectively. A radial spacing between the outer peripheral surface of the core and the outer peripheral surface of each of the rims is greater than a maximum thickness of the rollstock. Also provided are an unwinder assembly incorporating such a rollstock support spool and an automatic bagger incorporating such an unwinder assembly.
