Patent number: 5545285Abstract: The disclosure describes an apparatus and method for applying strips of tensioned elastic material transversely to a moving sheet or web of material, such as a component of a disposal diaper. The heart of the invention is a pair of inclinded, spaced apart transfer wheels located in mirror image relationship across the moving web. The transfer wheels are inclined relative to each other so that the distance between them is greatest at a point on their circumference that lies adjacent the web and least where a point on their circumference is at the greatest distance from the web. A supply drum provides an untensioned elastic strip to the transfer wheels at the point of least distance between them. As the transfer wheels move through 180.degree. of rotation, the elastic is stretched and then released at the plane of the web where it is adhesively bonded to the web. A drive system for the transfer wheels rotates them at a circumferential speed essentially equal to the linear speed of the moving web.Type: GrantFiled: November 16, 1994Date of Patent: August 13, 1996Inventor: Nordahl K. Johnson
