Abstract

Flats were made, which have wire fillet card clothings with wire-sets of 31mm adhered to flat bars of 33.3mm in width.With these flats, the relation between the sliver quality and the inclination of flats and the relation between the sliver qualit yand the flat acting angle were examined respectively.Besides, these newly made flats and ordinary flats with wire-sets of 22mm were compared.<BR>1) These newly made flats with the inclination of 1/37.5 are almost the same as ordinary flats in the amount of neps in the sliver.In newly made flats, the amount of neps decrease as the inclination of flats is made smaller than 1/37.5.This tendency is more remarkable in thecase of 90°of the flath acting angle than in the case of 75°.<BR>2) In these newly made flats, the amout of neps in the sliver is smaller in case of 90°than in case of 75°.<BR>3) In these newly made flats, the mean length of the fiber in the sliver remains same, regardless of the inclination of flats and the flat acting angle.
