Abstract
An elongate and arcuately curved yarn heating plate of the type adapted for use in a false twist yarn crimping machine which utilizes a specific relationship between the curvature of the heating plate and the heat imparted to the yarn so as to permit the length of the heating plate to be shortened as compared to conventional lengths. More particularly, the present invention involves the shortening of the radius of curvature of the heating plate from known and accepted values, which has been found to permit the length of the heating plate to be shortened while still providing adequate heat transfer to the yarn.
