ABSTRACT:
An arrangement for feeding sheets from a bundle of sheets includes a wheel, roller or belt which, in operation, is located at one end of the bundle and which functions to feed-out the outermost sheets of the bundle, and a lifting mechanism for lifting the bundle in a direction towards the wheel. The lifting mechanism includes a post and a bundle-carrying plate which is movable up and down the post. The arrangement includes a spring element which functions to lock the plate to the post in a rest state and has a free-end which is fitted to the post and defines, with the longitudinal axis of the post, an angle other than 90.degree. and whose remaining end is attached to the plate and movable perpendicular to the post. The arrangement also includes an actuator which is fitted to the post close to the spring element and which is releasably attached mechanically to a drive mechanism for moving the plate relative to the post. As the actuator is moved along the post, the actuator acts on the spring element so as to release the plate and enable it to move along the post.
