Title: A method in the production of double varnished packing blanks made from printed carton sheets,and a related production system and punching machine
Inventor: SCHUR AXEL
IPC: B41F23/08
Filed: 1992-03-11
Abstract: In the production of blanks for canon packings carton sheets are used which are at first printed corresponding to a number of printed and varnished packing blanks, whereafter the sheets, collected in piles, are moved to a station comprising one or more punching machines (6), in which the single blanks are punched out from the sheets. It happens that the blanks are desired to show a double varnished high gloss finish, and since it is hardly possible to effect more than a single varnishing in direct continuation of the printing, it is normal practice to make use of an additional varnishing unit (12) having an associated feeder (8), in which unit the prevarnished sheets are processed after being thoroughly dried, e.g. overnight. Thereafter the piles of double varnished sheets are brought to the relevant punching machine. According to the invention it has been found that it is perfectly possible to convey the sheets to the punching unit directly from the separate varnishing unit (12), through an intermediate drying station (16), whereby the work is facilitated and the feeder (8) on the selected punching machine (6) can be avoided. <IMAGE>
