ABSTRACT:
A method for producing an oriented plastic strap having a predetermined desired thickness for use in strapping packages and the like is passed between a pair of cylinders or rollers placed closely together at a desired nip for reducing the thickness of the sheet. One roller is rotated at a faster lineal rate of speed than the other, and the rollers rotate in opposite directions. This method achieves milling and stretching of the material substantially simultaneously at the nip of the rollers.
