Abstract
An assembly of closely spaced attachments, a method of manufacturing an assembly of closely spaced attachments and a method of applying interleaved attachments to objects. The assembly has alternating attachments having different types of heads and having different lengths. The shorter attachments may be subsequently stretched to engage the longer attachments. In this manner the spacing between attachments can be decreased. One result of using such an assembly with a conventional dispensing device is that the advancing mechanism of the device can advance attachments two at a time by only contacting a single position at every other attachment in the assembly.
