Abstract
An apparatus for the series application of patterns in the form of individual pattern elements to a spread, web-like flat structure, which pattern elements adhere thereto upon application of pressure and/or heat, comprising a transport device for the step-wise transport of the flat structure to which patterns are to be applied past work stations. At least one device serves for lifting at least one pattern element from a stack of pattern elements arranged upon a support, for transporting such lifted pattern element over the flat structure and depositing such thereon at a first work station. There is also provided at least one pressure and/or heat exerting device in order to adheringly bond the pattern element deposited upon the flat structure at a work station which follows the first work station in the direction of travel or transport of the flat structure. Control means serve for the step-wise transport of the flat structure past the work stations and control the working operations of the aforementioned devices in such a manner that when the flat structure is stationary, pattern elements are deposited thereon and at the same time previously deposited pattern elements are connected…
