Abstract (en)
Apparatus for splicing the end of a first printed web (20) to the beginning of a second printed web (22) to maintain a desired spacing between consecutive registration marks (24) printed on each of the webs. The apparatus includes a plate (62) that is adapted to contact a deflecting roller (40) to reduce the speed of the web (20) that passes over the roller (40), and for moving the plate (62) in a tagential direction relative to the roller (40) at a predetermined linear speed for a prdetermined interval of time. While the web has its speed reduce while passing around the deflecting roller (40), two oppositely disposed joining rollers (34, 34a) are caused to contact each other, one of the rolls carrying the leading end of the upstream web (20) and the other roll carrying the replacement web (22), the replacement web including a double faced tape (22a), the replacement web including a double faced tape (22a) to adhere the leading end of the replacement web to the trailing end of the initial web. A tension control roller (44) is provided downstream of the plate (62) and deflecting roller (40) to provide a loop of web, and movement of the tension control roller (44) to reduce the size of the loop permits the take-off speed of the web from the device to be maintained while the splicing operation takes place.
