Method for printing of packaging parts
First Claim
1. A method for printing packaging parts (2) comprising;
- providing packaging parts having at least two differently disposed surface levels (3, 4) in a vertical direction, the packaging parts (2) being a part of a continuous foil web (1), the packaging parts (2) lying at a distance from each other and being in connection with one another via the foil web, feeding the continuous foil web with the packaging parts forward towards a printing section (B), sensing a preselected portion of the packaging parts and stopping the feeding of the continuous foil web, calculating a position for printing a preselected number of the packaging parts in the printing section, advancing the foil web such that the preselected number of packaging parts arrive at the calculated position for printing and simultaneously sensing another preselected number of packaging parts to be printed which are stopped at an entrance to the printing section, and calculating a position for printing the preselected number of packaging parts stopped at the entrance to the printing section such that they are subsequently precisely advanced to the calculated position for printing.

Abstract
A method for printing packaging parts which constitute a part of a continuous web of foil 1, in that the individual packaging parts 2 lie at a distance from each other and are in connection with each other via the foil, whereby the continuous web of foil with the packaging parts is fed forward to a printing section B, where the printing of the packaging parts 2 is effected with print-pads 10, and each printing cycle comprises a packaging part or several packaging parts lying parallel and at the side of each other with a distance between them, and the position of the parts being sensed at an entrance to the printing station, a controller receiving a signal from the position sensor and calculating an amount of movement for precisely positioning the packaging parts for printing, and controlling a drive for the foil web to assure that the packaging parts are moved to the calculated position for printing.
