manner each of the internal carriers is angled somewhat differently from its neighbor thus each of the discs will be rotating in a slightly different direction from that of its neighbors an application for this version of the pulley lies in the control of webs which need to be stretched in a crosswise manner as referred to the web direction to a variable degree in this case the center disc 54 will have its particular rotating axis perpendicular to the web travel direction the neighbor discs on either side 56 and 57 will have their respective axes angled one to the right and one to the left each by a small degree other discs laying yet further from the center disc will have axes that are progressively slightly more angled in this manner the full width of the web is placed in tension by means of this cross web tension creases may be ironed out of the web as in running newsprint in another use the web may be stretched to a thinner thickness dimension as in the case of continuously stretching a deformable plastic web material referring to fig1 it will be seen that in this application the web 58 is not expected to wrap around the pulley.
