It is proposed that, during the receiving and/or outputting, the plate (14) carries out a non-linear compensation movement relative to the drum (12) with a radial movement component.

METHOD AND APPARATUS FOR DEPOSITING DISCRETE ELEMENTS ON A SUPPORT ELEMENT

A method and apparatus for depositing discrete elements on a support element. The discrete elements may be separated from each other or joined to form a continuous web. The discrete elements are fed into a pick-up station defined at a rotor which includes circumferentially adjacent pick-up members. Each discrete element is associated with a respective pick-up member having a first orientation with respect to a respective second axis of rotation. Each pick-up member is moved along the rotation direction towards a release position downstream with an at least partially accelerated or decelerated motion. Each pick-up member is rotated about the respective second axis of rotation until it takes, at the release position, a second orientation. Each discrete element is released on a support element at the release position. Each pick-up member is subsequently moved towards the pick-up station with an at least partially decelerated or accelerated motion.
