  • Patent number: 10266285
    Abstract: A method for producing partially embossed blanks is disclosed. The method is to provide a continuous web of an embossable material, and guide it between two cylinders which emboss its surface. The embossed web is fed to a stamping device to punch blanks from the web. One of the embossing cylinders has a marking which is readable by a first sensor. The first sensor reads the position of the marking and produces a signal which triggers a printing device to produce a print mark on the web identifying the position of the embossing. The print mark is read by a second sensor which produces a signal for controlling and adjusting a feeding distance by which feed rolls supply the web to the stamping device that punches blanks from the web in register with the partial embossing of the blank. A device for conducting the method is also disclosed.
