  • Method and apparatus for producing chopped strands
    Patent number: 4537610
    Abstract: Method for producing discrete bundles of filaments includes applying a non-aqueous, hot melt coating material to continuous filaments and gathering the coated continuous filaments into a bundle. The coating material is solidified on the continuous filament bundle so as to establish a first cross-sectional shape and the bundle is then severed into discrete segments whereby the bundle segments are deformed so as to exhibit a second cross-sectional shape at the severed regions. The bundle segments are then heated sufficiently to soften the coating material to permit the bundle segments to substantially return to the first cross-sectional shape.The apparatus of the invention includes a primary applicator for applying a production coating to the filaments and an interim applicator for applying a start-up coating to the filaments.
