- flying pasters usually have two or three roll mounts
- they require precise timing to splice properly
- have other functions such as roll alignment and tension control
- are used on high speed web offset heatset presses

2. The splicing arm comes down to a position that puts the running roll in very close proximity to the new running roll.
3. A signal is given when the expiring roll is down to the minimum diameter.
4. The splicing arm quickly presses the running roll against the new roll at the precise spot where the two sided tape has been placed.
5. The splicing arm cuts the expired web immediately after pasting onto the new roll.
6. The new roll rotates into a running position that allows the expired roll to be unloaded and a new one accepted.
Many flying pasters have web guidance systems built in. While many offset presses have a steering box after the rollstand, newer flying pasters work by moving the actual roll. A closed loop system will then keep the running roll aligned with the press.
