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;
- structure for mounting said material dispensing assembly upon said module assembly;
- and
- a strand positioning guide mechanism mounted in a surface-to-surface contact manner 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, triangular cross-sectional configuration, comprising a base portion and an apex portion, and wherein, when said strand positioning guide mechanism is mounted upon an undersurface portion of said module assembly, said strand guide slot of said strand positioning guide mechanism is oriented such that said base portion is disposed beneath said at least one material dispensing nozzle while said apex portion of said at least one strand guide slot is located upon said strand positioning guide mechanism so as to be disposed beneath said base portion remote from said at least one material dispensing nozzle such that the at least one elongated strand of material will not be adversely affected by thermal radiation emanating 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;
- structure for mounting said material dispensing assembly upon said module assembly;
- and
- a strand positioning guide mechanism mounted in a surface-to-surface contact manner 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, triangular cross-sectional configuration, comprising a base portion and an apex portion, and wherein, when said strand positioning guide mechanism is mounted upon an undersurface portion of said module assembly, said strand guide slot of said strand positioning guide mechanism is oriented such that said base portion is disposed beneath said at least one material dispensing nozzle while said apex portion of said at least one strand guide slot is located upon said strand positioning guide mechanism so as to be disposed beneath said base portion remote from said at least one material dispensing nozzle whereby the at least one elongated strand of material will be spaced a predetermined distance from said material dispensing assembly, having said 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.
