摘要： A three roller film winder and method for loading photographic film. In the method, a film cartridge is positioned in a cartridge chamber of a camera frame assembly. The camera frame assembly has the cartridge chamber, a supply chamber, and an intermediate section between the chambers. The film cartridge includes a spool and a filmstrip. The filmstrip has leading, main, and tail portions. A sleeve is introduced into the supply chamber. An upper roller is disposed over the sleeve. A pair of lower rollers are introduced into the supply chamber. The upper and lower rollers together define a substantially cylindrical scroll space. The leading portion of the filmstrip is advanced out of the cartridge and into the sleeve. The leading portion is curled within the sleeve and scroll space into an initial filmstrip scroll having at least one turn. The sleeve is retracted after the curling step. The main portion of the filmstrip is propelled between the upper and lower rollers to wind the main portion over the initial scroll. During the propelling, the spatial separation of the lower rollers from the upper roller is increased. This increases the diameter of the scroll space. The rollers are removed and the camera frame assembly is light-tightly closed.
摘要翻译：一种用于装载摄影胶片的三辊胶卷卷绕机和方法。在该方法中，将暗盒定位在相机框架组件的暗盒室中。相机框架组件具有盒室，供应室以及室之间的中间部分。暗盒包括卷轴和胶卷。影片有主要的，主要的和尾部的部分。将套筒引入供应室。上辊被设置在套筒上。一对下辊被引入供应室。上辊和下辊一起限定了大致圆柱形的涡旋空间。胶片的前导部分从盒中推出并进入套筒。前导部分在套筒内卷曲，并将空间滚动到具有至少一圈的初始胶片卷轴上。在卷曲步骤后套筒缩回。胶卷的主要部分在上辊和下辊之间推动，以将主要部分卷绕在初始卷轴上。在推进期间，下辊与上辊的空间分离增加。这增加了滚动空间的直径。拆下滚筒，并将相机机架组件轻轻关闭。

摘要： A method and apparatus for loading photographic film. In the method, a curling guide is introduced into a supply chamber of a film holder. An inner roller is introduced into the supply chamber. The inner roller defines an inner roller axis and a film gap overlying the inner roller. An outer roller is disposed over the inner roller adjoining the film gap. A leading portion of a filmstrip is advanced through the film gap. The leading portion is curled around the inner roller and back to the film gap to define an initial filmstrip scroll. The initial scroll has an axis offset from the inner roller axis. The curling guide is retracted after the curling step. The main portion of said filmstrip is propelled through the film gap to wind the main portion of the filmstrip over the initial scroll. The rollers are removed. The film holder is light-tightly closed.
摘要翻译：一种用于装载摄影胶片的方法和装置。在该方法中，将卷边引导件引入到胶片保持器的供给室中。内辊被引入供应室。内滚轮限定内滚子轴线和覆盖内滚筒的薄膜间隙。外辊设置在邻近膜间隙的内辊上。电影胶片的前导部分通过胶片间隙推进。引导部分卷绕在内辊周围并返回到胶片间隙以限定初始胶卷卷轴。初始卷轴的轴线偏离内滚轴。在卷曲步骤之后，卷曲导片缩回。所述胶卷的主要部分通过胶片间隙推动，以将胶片的主要部分卷绕在初始卷轴上。滚筒被取下。胶片夹紧紧闭合。
