ABSTRACT:
An elastic band sealer for forming a continuous non-overlapping band from a source of material in which the band sealer includes apparatus to extend a length of material from the source, apparatus to cut the material into a strip after it is extended, and apparatus to fuse the strip into a continuous non-overlapping band. The band sealer can also include apparatus 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 and additional apparatus 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.
