Abstract:
A method of repeatedly stamping a foil image onto an elongated product web, each said stamped image being positioned a fixed longitudinal distance apart along said product web, said fixed distance corresponding to a defined product length, the method comprising the steps of:providing a rotary die holder having a rotary die thereon, said die extending over less than the full circumference of said die holder and defining a raised surface in the form of the image to be stamped onto said product web; providing a rotary counter roll, and positioning said counter roll adjacent to and spaced apart from said die holder such that the surface of the die engages said counter roll when the die holder rotates the die between the die holder and the counter roll; rotating said die holder at a constant speed so that the surface of the die is rotated against said counter roll at regular timed intervals; feeding a product web and a foil web in a forward direction between said die holder and said counter roll at a first feed rate during the periods when the surface of the die is engaging the counter roll; feeding said product web in a forward direction at a second product web feed rate during a period when the surface of the die does not engage said counter roll, wherein the second product web feed rate is different than the first product web feed rate, and wherein the second product web feed rate is greater than the first product web feed rate.
