Abstract:
1. An opening method for continuous filaments, comprising the steps of: transporting crimped tow by means of a plurality of rolls; and applying a resistance on at least one side of said tow by slidingly contacting a plurality of sliding bodies onto said tow at a position between said rolls, whereby continuous filaments stacked in a thickness direction of said tow are caused to shift in a transporting direction of said tow to open said tow and to spread said continuous filaments in a latitudinal direction of said tow, wherein each side of said tow is slidingly contacted by at least one of said sliding bodies, and each sliding body is adjustable about a tilt angle relative to a line perpendicular to a transporting path of said tow and a penetration amount into the transporting path of said tow.
