Abstract

A method of and device for attaching a web of material rolling off to a processing machine to the beginning of a fresh web that is wound on a reel. To provide a method that will inexpensively and rapidly ensure a reliable attachment between the two webs, the first web is separated upstream of a stored section with the processing machine turned off and the separated section at least partly reserved, the section of web with the second web is then forced into contact, and the end of the reserved web section attached to the beginning of the second web as it arrives by releasing the reserved web section with the processing machine in operation. The device comprises an upright with the replacement reel mounted on it, a mechanism for reserving a supply of web, and a mechanism for cutting the web. To provide a device for carrying out the method that will be simple in design and universally applicable, a transfer mechanism that accommodates at least part of a separated section of the first web and that can be forced into contact with the outer surface of the replacement reel is positioned between the cutting mechanism and a reservoir.
