摘要: A film flattening apparatus and method of operation for a printer particularly operable in mode image frames filmstrip segments attached by side tow web transported through transport path gap between the an aperture formed stationary base. The is first second clamping members suspended apart from base retracted position during moved toward to contact pressing against longitudinal or lateral transverse edges frame mode. are with longitudinally transversely extending elements, respectively one another advance sequentially nested relation In mode, elements guide tend flatten excessively, curled segments. positioned further out interference segment leading ends centrally member. Preferably, has thickness within which sculpted, arcuate reliefs centered on mid-point opening provide upward guidance
