Abstract
Apparatus for extending film tube from high density polyethylene biaxially oriented in longitudinal or machine direction as well as in cross machine diameter-increasing direction, and for joining extruded closure strip carried helically on one wall of the tube correspondingly stretched as a result of the biaxial stretching to which the film of the tube is stretched. The closure-strip-carrying, biaxially oriented tube is adapted to be converted into a ribbon sheet form with the closure strip extending as individual closure strip sections across the ribbon sheet form at longitudinally spaced intervals, and adapted for making bags.
