Abstract
The invention pertains to a apparatus for performing operations, in particular cutting, embossing, creasing, folding and/or sealing, on a moving web provided with a series of identical images, which apparatus comprises a sensor for at least partially detecting the images on the web, and a processing unit which, dependent on a comparison of the data obtained with the sensor and a reference, generates an output signal to be used for one or more of the said operations. The processing unit comprises a memory and is arranged to select at least part of the detected data, store the selected data in the memory, and utilize the selected data as the reference. The invention further pertains to module for performing operations on a moving web and method of generating an output signal.
Claims11
An apparatus for performing cutting, embossing creasing, folding and/or sealing, on a moving web provided with a series of identical images, which apparatus comprises a sensor for at least partially detecting the images on the web, and a processing unit which, dependent on a comparison of data obtained with the sensor and a reference (R), generates an output signal to be used for one or more of the said operations, wherein the processing unit comprises a memory and in that the processing unit is arranged to select at least part of the detected data, store the selected data in the memory, and utilize the selected data as the reference (R), and wherein the processing unit is arranged, if data obtained with the sensor deviates from the reference (R), to store such deviation data in the memory and, if such deviation data occurs again, to utilize the deviation data as the reference (R).
A module for use in a apparatus for performing cutting, embossing, creasing, folding and/or sealing, on a moving web provided with a series of identical images, which module comprises:
- an input to be connected to a sensor for at least partially detecting the images on the web;
- a memory;
- and
- is arranged to select at least part of the data received at the input, store the selected data in the memory, utilize the selected data as a reference (R), and, dependent on a comparison of the data obtained with the sensor and the reference (R), generate an output signal to be used for one or more of the said operations, and, if data obtained from the sensor deviates from the reference (R), to store such deviation data in the memory and, if such deviation data occurs again, to utilize the deviation data as the reference (R).
A method of generating an output signal to be used for one or more apparatus operations comprising cutting, embossing, creasing, folding and/or sealing, on a moving web provided with a series of identical images, which method comprises:
- at least partially detecting the images on the web,
- selecting at least part of the detected data,
- storing the selected data in a memory as a reference (R),
- generating, dependent on a comparison of subsequently obtained data and the reference (R), the said output signal, and
- if data obtained from the sensor deviates from the reference (R), to storing such deviation data in the memory and, if such deviation data occurs again,
- utilizing the deviation data as the reference (R).
