Method for checking the formation of continuously advanced products.

摘要

In order to check the formation of continuously advanced (conveyed) products, preferably the formation of folds and/or the formation of bottoms of paper bags and/or impressions or the like, a picture is taken of the area to be checked by a CCD semiconductor camera, and the picture is checked visually or is compared, by a processor, with a pattern corresponding to the required formation of the product. In order to be able to carry out the check of the bottoms on a short conveyor section, successively at least two part pictures of the area to be checked of the product are taken, which can be combined into the whole area to be checked.
