<p>An elastic band sealer for forming a continuous non-overlapping band from a source (3) of material in which the band sealer includes apparatus (22) to extend a length of material from the source, apparatus (15, 16) to cut the material into a strip after it is extended, and apparatus (40, 41) to fuse the strip into a continuous non-overlapping band. The band sealer can also include apparatus (19-21) to measure the extended length of material such that it may be cut into discrete strips. The apparatus for fusing the strip generally includes a heating head (41) and additional apparatus (32-35) which rotates the ends of the strip toward one another such that the heating head can fuse the strip into a continuous non-overlapping band. A method of forming a continuous non-overlapping band from a source of material is also considered, which includes extending a length of the material from the source, cutting the material into a strip after it has been extended, and fusing the strip into a continuous non-overlapping band.</p> |
