Abstract
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.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
73 words
An elastic band sealer comprising: (a) means to feed elastic from a source of elastic; (b) means to pull said elastic from said feed means; (c) means to serrate said elastic into a strip after it is pulled said strip having ends; and (d) means to fuse said strip into an elastic band including means to rotate said ends toward one another to form a continuous band without any overlapping of said strip.
Claim 2
Dependent Claim
73 words
An elastic band sealer comprising: (a) means to feed elastic from a source of elastic; (b) means to pull said elastic from said feed means; (c) means to serrate said elastic into a strip after it is pulled said strip having ends; and (d) means to fuse said strip into an elastic band including means to rotate said ends toward one another to form a continuous band without any overlapping of said strip.
Claim 3
Dependent Claim
32 words
The elastic band sealer of claim 1, wherein said means to fuse said strip includes a heating head capable of partially melting said elastic strip and fusing it into an elastic band.
Claim 4
Dependent Claim
20 words
The elastic band sealer of claim 1, wherein said means to pull said elastic includes means to measure said elastic.
