Claims
- 1. In an apparatus for forming a pair of web panels for use in preparing protective garments from sheets of polymeric materials, said apparatus having a pair of platens which have an open and closed position, wherein the improvement comprises: one platen having a first heating element comprising a wire in a pattern to form two halves of a protective garment, each half having a seamed leg and arm portion, spring means tensioning said first heating element, and the other platen having a second heating element comprising a band which is adjacent to said first heating element so as to be in a side-by-side relationship causing a scissoring effect when the platens are in the closed position, said pattern configured to form first and second adjacent panels, each panel having a leg portion and an arm portion with the leg portion of the first panel being adjacent to the arm portion of the second panel and the arm portion of the first panel being adjacent to the leg portion of the second panel, and heating means on each platen for separately heating said first and second heating elements at different temperatures so as to cut and fuse the polymeric material when the platens are placed in the closed position.
- 2. The apparatus of claim 1 wherein said heating element comprises a metallic wire.
- 3. The apparatus of claim 1 wherein said heating element comprises a metallic band.
- 4. The apparatus of claim 1 including means for feeding sheets of polymeric materials between said platens.
- 5. The apparatus of claim 1 wherein said first heating element is coated with a halogenated hydrocarbon.
- 6. In an apparatus for forming web panels for use in preparing protective garments from sheets of polymeric material, said apparatus having a pair of platens which have an open and closed position, wherein the improvement comprises: said platens have on each surface that comes in contact with said sheets, at least one heating element forming a pattern for said element on each of said platens, said pattern configured to form first and second adjacent panels, each panel having a leg portion and an arm portion with the leg portion of the first panel being adjacent to the arm portion of the second panel and the arm portion of the first panel being adjacent to the leg portion of the second panel, said heating elements on each of the platens are positioned so as to be in a side-by-side relationship causing a scissoring effect when the platens are in the closed position, and heating means on each platen for separately heating said heating elements to different temperatures so as to cut and fuse the polymeric material when the platens are placed in the closed position.
