that the circular cam plate 33 sits down inside the center of the support pulleys 32 so that the circular cam plate 33 cannot jump out of the support pulleys 32 during use the circular cam plate 33 is comprised of a single unitary structure that is configured with a large centered opening 44 by large what is meant is that the opening 44 must be large enough to allow for the movement of the slidable elements of the pocket cassettes 37 back and forth within the centered opening 44 which slidable elements are discussed infra the circular cam plate 33 also has a center axis 43 running through the center of the opening 44 and exiting through the centered opening of the second circular cam plate 91 fig1 located on the opposite end of the lip rolling cassette 92 which second circular cam plate 91 will be discussed infra the circular cam plate 33 also has regularly spaced semi circular openings 45 fig3 through it which accommodates the perpendicular roller bearing pins 42 therein this accommodation allows the perpendicular roller bearing pin 42 to slide therein along the configuration of the semi circular openings 45 to assist in and participate in the adjustment of.
