  • Patent number: 7827667
    Abstract: A packaging arrangement for smoothly and conveniently providing small hardware items to an assembly line operator is described. The items are fastened onto a flexible band, lined up in the order in which they are to be installed on an article being assembled. The band is divided into equal segments defined by index marks, each segment containing the hardware items required for the assembly of one article. The items are fastened to the band off-line using securing features fashioned from the band itself in a manner and orientation by which each item can be plucked from the band with a tool that can grasp the item, pull it off the band, transport it to the article being assembled, and install it on the article without intermediate disengagement from the tool. The utilization of the band improves the productivity and reliability of manually assembled articles such as disk drives.
