ABSTRACT:
A machine for wrapping a plurality of individual packages, or other containers arranged in a bundle, with a stretchable material, of generally transparent constituency, said machine including automatic means to wrap said bundle of packages with successive layers of such overlapping stretchable material, and said machine including additional automatically actuated holding and cutting bars which serve to cut the trailing edge of said wrapped material while the wrapping material is disposed in a vertical position, with further means on said machine to position said holding and cutting bars in a position beneath the load to be wrapped in order that said holding and cutting bars do not interfere with the wrapping cycle. Said holding and cutting bars may optionally have electrically headed resistance wires integrally disposed therein for facilitating the process of cutting the wrapping material at the end of the wrap cycle.
