ABSTRACT:
An unwind stand provides apparatus for aligning and tracking reclosable stock pouch material having a thickened pouch closure formation. Substantially vertical material runs provide a material path of significant distance between a level wind supply roll, from which stock material wavers transversely as it is unwound, and biased guide and alignment apparatus for aligning the material against transverse movement. Loop forming apparatus and unwinding and alignment method steps are included.
