A stable, continuous, high-speed roll film media path is established between supply and take-up film reels. Supply and take-up path segments isolate a core transport path section from significant non-linear forces, thereby enabling continuous, high-speed, high-accuracy scan line imaging of the media. The supply and take-up path segments each operate to continuously maintain open decoupling loops in the film media while accurately controlling the speed, tension and alignment of the film media as transported through the core transport path section. A microcontroller operates two motor driven capstans to establish the film media speed and tension within the core transport path section. Optical sensors provide feedback to the microcontroller in managing two additional motor driven capstans to maintain the decoupling loops. The film media within the core transport path section is thereby isolated from frictive, inertial, and skewing forces that could otherwise degrade the media imaging.

The invention relates to a method for smoothing the speed of a high speed numerical control processing track corner in the numerical control processing field wherein, initial speed of a transition curve generation place of the corner is determined according to processing errors of the corner, acceleration and profile; interpolation motions are performed simultaneously through adjacent processing sections under the condition of corner transition according to a space vector theory; a transition curve of the corner transition is synthesized by addition of displacement vectors which are obtained according to interpolations of the adjacent processing sections, thereby speed smoothing transition is realized. The invention simultaneously performs the interpolation motions in the adjacent processing sections under the condition of corner transition; a transition track obtained is continuous and derivable, and speed in the corner transits smoothly and can not be reduced to zero, thereby the speed during the manufacturing process can not start and stop frequently. Simultaneously, transitional initial speed is related to preset allowable processing profile errors, thereby processing precision of the transition track can be guaranteed, and speed smooth transition on the high speed numerical control processing corner is realized.
