Abstract
Strand positional guide implements, for use in connection with hot melt adhesive strand coating applicator assemblies, comprise a plurality of V-shaped strand guide slots wherein the apex portions are oriented outwardly away from the hot melt adhesive material dispensing nozzles. Accordingly, an enlarged air space is effectively defined between the plurality of elongated strands and its respective hot melt adhesive material dispensing nozzle such that the plurality of elongated strands are not adversely affected by the heat or thermal radiation generated by or emanating from the hot melt adhesive material dispensing nozzles thereof.
Claims20
A strand guide system for guiding at least one elongated strand of material past a material dispensing apparatus such that material dispensed from the material dispensing apparatus can be properly coated upon the at least one elongated strand of material, comprising:
- a material dispensing assembly having at least one material dispensing nozzle disposed thereon for dispensing a material to be coated upon at least one elongated strand of material as the at least one elongated strand of material is conveyed past said at least one material dispensing nozzle;
- a module assembly for supplying the material to be dispensed to said material dispensing assembly and said at least one material dispensing nozzle disposed upon said material dispensing assembly;
- means for mounting said material dispensing assembly upon said module assembly;
- and
- a strand positioning guide mechanism mounted upon said module assembly and having at least one strand guide slot defined therein for guiding the at least one elongated strand of material as the at least one elongated strand of material is conveyed past said at least one material dispensing nozzle, wherein said at least one strand guide slot has a substantially V-shaped cross-sectional configuration, comprising an apex portion, with said apex portion of said at least one strand guide slot oriented so as to extend remotely away from said at least one material dispensing nozzle.
A strand guide system for guiding at least one elongated strand of material past a material dispensing apparatus such that material dispensed from the material dispensing apparatus can be properly coated upon the at least one elongated strand of material, comprising:
- a material dispensing assembly having at least one material dispensing nozzle disposed thereon for dispensing a material to be coated upon at least one elongated strand of material as the at least one elongated strand of material is conveyed past said at least one material dispensing nozzle;
- a module assembly for supplying the material to be dispensed to said material dispensing assembly and said at least one material dispensing nozzle disposed upon said material dispensing assembly;
- means for mounting said material dispensing assembly upon said module assembly;
- and
- a strand positioning guide mechanism mounted upon said module assembly and having at least one strand guide slot defined therein for guiding the at least one elongated strand of material as the at least one elongated strand of material is conveyed past said at least one material dispensing nozzle, wherein said at least one strand guide slot has a substantially V-shaped cross-sectional configuration, comprising an apex portion, with said apex portion of said at least one strand guide slot oriented so as to extend remotely away from said at least one material dispensing nozzle whereby the at least one elongated strand of material will be sufficiently spaced from said material dispensing assembly, having at least one material dispensing nozzle disposed thereon, so as not to be adversely affected by thermal radiation emanating from said material dispensing assembly and said at least one material dispensing nozzle disposed thereon.
