摘要:
A method for incorporating graphics (21, 21a, 21b) into absorbent articles (10). The method involving: providing a moving substrate (17) to a print cylinder (85); sensing a line speed reference signal from a line speed target machinery component; rotating the print cylinder (85) at a predetermined speed, based on the line speed reference signal, printing a series of graphics at a predetermined distance frequency; sensing a phase difference signal from a phase target machinery component; and setting an actual print cylinder phase angle, based on the phase difference signal, to thereby position a series of graphics.
摘要:
The web leading edge (E) of a paper roll (R) for a rotary press or the like is held and prevented from raveling by three or more pieces of strong adhesive tape (Ta) during handling and loading onto a paper feed machine of the printing press. On the paper feed machine, perforated tear lines (15) are formed across the tape pieces (Ta) by a device comprising a rotary perforating wheel (42). a mechanism for moving the wheel from one end to the other ofthe roll (R) and also moving it against and away from all of the tape pieces (Ta), and a tape detecting device (BS) and a controller (45) for automatically operating the mechanism. The tape pieces (Ta) can then be easily torn to release the web leading edge (E) immediately prior to web splicing.
