ABSTRACT:
The present invention provides a process and apparatus for the separation of strip sections from a first moving material web, for the subsequent application of these strip sections on discrete areas lying at a distance one behind the other of a likewise moving second material web, wherein the predetermined distance is achieved by moving the separated strip sections apart. In the case of a transfer of the strip section to the second material web, the strip sections and the second material web are kept at an equal constant speed during the entire transfer process. The apparatus for carrying out the process comprises a multiplicity of conveying elements rotating on a circular periphery. In the peripheral direction, the conveying elements have a distance to one another which changes during each rotation. A bipartite lever rod system takes care of this change of distance between the conveying elements which system always connects a conveying element with a common driving disc. The lever rod system is controlled on a curve path in such a way that the conveying elements may rotate at a constant speed over extended stretches.
