Abstract
A takeup magazine is provided for automatically loading a strip of material such as photographic film onto a removable core. A housing contains a rotatable platter. A friction ring is mounted coaxially above the platter for rotation therewith. A removable core having a diameter smaller than that of the friction ring is mounted coaxially above the platter for rotation with the platter and the friction ring. An opening in the housing receives an end of a strip of material to be wound onto the core. The end of the material is guided to engage the core and the friction ring when the strip is pushed into the opening. The guiding of the strip can be accomplished using a first pivoting arm for guiding the end in the direction of the core and at least one second arm for urging the strip against the core.
