METHOD AND APPARATUS FOR OPENING CONTINUOUS FILAMENT

摘要

PROBLEM TO BE SOLVED: To solve a problem that in opening a crimped tow, qualities of a fiber layer after opening are not stabilized and the change of various opening conditions is difficult when the kind of the tow is changed. SOLUTION: Sliding plates 11 and 12 are brought into contact with a crimped tow 2A being transported between a transfer roll 4a and transfer rolls 5a and 5b. Continuous filaments arranged in the thickness direction of the tow 2A are provided with a shear by a sliding force produced when the tow 2A is slid on the sliding plates 11 and 12 and opened so that a fiber layer 2B in which the continuous filaments are dispersed in the width direction can be obtained.
