ABSTRACT:
A cylindrical guide for varying the width of a bundle of continuous filaments has a surface in contact with the bundle that has an array of nonparallel grooves. The grooves converge until a minimum distance is reached on the guide surface and from thereon diverge to a maximum distance. With this arrangement of grooves it is possible to control the width of the bundle of filaments in a widening or narrowing manner by simply rotating the cylindrical guide one direction or the other until the desired width is reached.
