    摘要： An apparatus and 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 apparatus and method achieves milling and stretching of the material simultaneously substantially at the nip.

    摘要： A strap (20), which can be a strip of metal, is provided for forming a tight loop about an object and for forming a sealless strap connection between overlapping strap portions. The strap has first and second oppositely facing surfaces (31,32) and two connecting regions (41,42) spaced apart lengthwise on the strap. Each connecting region has at least one joint element (44,46) for engaging a corresponding joint element on the other connecting region to connect the regions together upon displacement of the connecting regions lengthwise in opposite directions tending to increase the loop size. An engaging member (80) projects from the strap first surface at one of the connecting regions. A cavity (86) is defined in the strap at the other of the connecting regions and opens to the strap second surface for receiving the engaging member. The cavity is defined at one end by an abutment surface (92) for being engaged by the engaging member. The cavity is located on the strap relative to the engaging member so that, after the strap connecting regions have been relatively displaced lengthwise in the direction tending to increase the loop size and effect engagement between the joint elements, the engaging member can engage the abutment surface. This prevents relative lengthwise displacement of the connecting regions in the directions tending to decrease the loop size which would effect disengagement of the joint elements.
