Apparatus for transferring labels or like flexible sheets

摘要

An apparatus for the transferring of labels or like flexible sheets, e.g. to a transfer drum or the application to bottles or other receptacles, comprises a pickup drum which is formed with a plurality of pickup heads adapted to roll along a stack of labels in a magazine and pick up an individual label for subsequent delivery to the transfer drum. The pickup face is formed as an involute, symmetrical about a median plane perpendicular to its pivot axis and has progressively increasing radius of curvature from a region proximal to the pivot and extending to either side away therefrom.
