    • A method for reducing curl in a stored photographic film which aids in preventing serious difficulties with downstream film transport and handling of the film. The film, which has been stored as a roll wound on a first core or mandrel is unwound from the first core and wound onto a second core or mandrel in a first direction. The film is then unwound from the second core to yield a traveling web portion. The traveling web portion is preheated to a predetermined temperature while being continuously delivered to a housing. The film is wound onto a third core or mandrel located within the housing in a direction opposite the first direction where it is maintained at about the same predetermined temperature.
    • 一种用于减少保存的照相胶片中的卷曲的方法,其有助于防止膜的下游胶片输送和处理的严重困难。 已经被卷绕在第一芯或心轴上的卷存储的薄膜从第一芯展开并在第一方向上卷绕到第二芯或心轴上。 然后将薄膜从第二芯展开,以产生行进的纤维网部分。 行进的腹板部分被预热到预定的温度,同时被连续输送到壳体。 该薄膜沿着与第一方向相反的方向卷绕在位于壳体内的第三芯或心轴上,在该方向上保持大约相同的预定温度。
