    Abstract: A method of copying a three-dimensional surface having X, Y, and Z dimensions forms a translucent impression of the surface to be copied and then captures a two-dimensional image of the translucent impression. The captured image has X and Y dimensions and a grayscale value for each X, Y coordinate of the image. Then, the method converts each grayscale value of the image to a Z height value, thereby generating a digital file of X, Y, and Z values. The digital file may then be provided as an input to a numerically controlled machine, which can be operated to reproduce the surface to be copied. The method of the present invention finds particular application in digitizing handcrafted emboss dies and the like.

    Abstract: A rotary embossing machine includes an embossing mechanism in which an embossing gap is formed between an embossing cylinder and a counter pressure cylinder. For conveying an embossing film web through the embossing gap, the rotary embossing machine includes a conveying mechanism for producing a movement of the web at the same speed as a material layer to be embossed, during an embossing interval. The film conveying mechanism includes a pulling device downstream of the embossing gap which is provided with a slip drive for the embossing film web and a controllable film supply device upstream of the embossing gap which cooperates with the pulling device. This arrangement avoids the risk of the embossing films or foils tearing and improves the embossing quality.

    Abstract: A system is disclosed for securing registration of a patterned embossing roll with a similarly patterned printed moving web. The purpose of the embossing roll is to indent the surface of the printed web in register with the printing in certain designated areas. In one embodiment, a series of randomly spaced register marks on the printed web selvage edge and identically spaced register marks on the embossing roll are viewed by appropriate scanners. Electrical signatures representing the two sets of register marks are generated by the sensors and fed to a signal correlator for comparison. The correlator determines the degree of statistical error between the two signatures and displays this error in the form of a time delay on a CRT (Cathode Ray Tube). If manual registration control is desired, an operator can manually adjust the speed or phase of the embossing roll by observing the peaked wave display on the CRT to bring the roll into a statistical best fit of the embossing pattern with the printed pattern. Automatic control of embossing roll speed and orientation to achieve registration is also possible if the correlator is interfaced with a digital computer and servo correction motors on the embosser drive system. The disclosed system is an improvement over conventional benchmark oriented registration sensing and control systems in that it is capable of continuous error determinations and asynchronous error corrections on demand rather than periodically at the end of pattern length intervals.

    Abstract: The invention relates to a device for the treatment of packaging foils, comprising a first embossing unit having at least one embossing roll provided with embossing structures (7) that are arranged in a basic grid for satinizing and/or with embossing structures which deviate from the basic grid for the application of logos and/or of authentication features, the work cadence (A1) of the first embossing unit being synchronizable to a process cadence (P) of the packaging process, as well as a first regulating unit of the first embossing unit that is synchronizable to the process cadence (P) of the packaging installation, and a second regulating unit of the second embossing unit, the second regulating unit serving for the synchronization of the work cadence (A2) of the second embossing unit to the work cadence (A1) of the first embossing unit. To ensure a superior foldability of the packaging foil at a high process velocity during the subsequent packaging process, a subsequent second embossing unit is suggested which comprises at least one folding roll for applying folding breaks to the packaging foil.

    Abstract: A rotary die apparatus and method for determining a registration error of a pattern applied to a strip of material by a rotary die. The rotary die apparatus may comprise the rotary die and a control system which senses signals from a sensor and a rotary encoder to determine an actual position of the rotary die when a fiducial on the strip of material is sensed. The control system may calculate the registration error by comparing the actual position with a registration target corresponding to a pattern length. The pattern length may correspond to the number of encoder pulses output per revolution of the rotary die divided by the number of patterns spaced apart around the circumference of the rotary die. An encoder count used to determine the actual position of the rotary die may reset each time it reaches the pattern length.
