Abstract
Improved web printing and handling apparatus (10, 84, 88) is provided which includes an improved digital printing assembly (12) having a bidrectionally rotatable impression drum (18) presenting an outer surface (20), as well as at least one digital print head (22) adjacent the drum outer surface (20). The overall apparatus (10, 84, 88) also has a downstream web cutting and handling assembly (14) with an adhesive applicator (32), laser cutter (40) and image collection assembly (44). In use, a web (16) traverses the drum (18) with essentially no relative movement between the web (16) and drum surface (20), and the print head(s) (22) are actuated to form individual images on the web (16). Thereafter, the printed web passes into and through the assembly (14) where adhesive is applied and the individual images are laser cut and collected using assembly (44).
