Web guiding apparatus
View Patent ↗A web guiding apparatus is provided. The web guiding apparatus includes an angle bar and an angle bar support supporting the angle bar. The angle bar support has a first end portion and a second end portion. The web guiding apparatus also includes a first actuator coupled to the angle bar support for moving the first end portion along a vertical axis and a second actuator coupled to the angle bar support for moving the second end portion along a horizontal axis. A folder for a printing press is also provided.
1. A web guiding apparatus comprising:
a first support;
a second support;
a first angle bar for guiding a first web movably coupled to the first support and the second support; and
a second angle bar for guiding a second web movably coupled to the first support and the second support;
the first support being coincident with a vertical axis and the second support being coincident with a horizontal axis.
2. The web guiding apparatus recited in claim 1 further comprising:
a first angle bar support coupling an upper end of the first angle bar to the first support and a second end of the first angle bar to the second support; and
a second angle bar support coupling an upper end of the second angle bar to the first support and a lower end of the second angle bar to the second support.
3. The web guiding apparatus recited in claim 1 further comprising at least one further angle bar coupled to the first support and the second support.
4. The web guiding apparatus recited in claim 1 further comprising a horizontally aligned first compensator roll upstream of the first angle bar for guiding the first web in a horizontal orientation to the first angle bar, the first angle bar configured to reorient the first web to a vertical orientation.
5. The web guiding apparatus recited in claim 4 further comprising a horizontally aligned second compensator roll upstream of the second angle bar for guiding the second web in a horizontal orientation to the second angle bar, the second angle bar configured to reorient the second web to a vertical orientation.
6. The web guiding apparatus recited in claim 5 further comprising a pair of vertically aligned gather rolls downstream of the first and second angle bars for merging the vertically oriented first and second webs.
7. The web guiding apparatus recited in claim 6 further comprising a horizontally aligned former downstream of the gather rolls for longitudinally folding the merged first and second webs.
8. A web guiding apparatus comprising:
a first support;
a second support;
a first angle bar for guiding a first web movably coupled to the first support and the second support;
a second angle bar for guiding a second web movably coupled to the first support and the second support;
a first actuator for moving the first angle bar with respect to the first support;
a second actuator for moving the first angle bar with respect to the second support;
a third actuator for moving the second angle bar with respect to the first support; and
a fourth actuator for moving the second angle bar with respect to the second support.
9. The web guiding apparatus recited in claim 8 further comprising:
a first angle bar support coupling an upper end of the first angle bar to the first support and a second end of the first angle bar to the second support; and
a second angle bar support coupling an upper end of the second angle bar to the first support and a lower end of the second angle bar to the second support.
10. The web guiding apparatus recited in claim 8 further comprising at least one further angle bar coupled to the first support and the second support.
11. The web guiding apparatus recited in claim 8 wherein the first support is coincident with a vertical axis and the second support is coincident with a horizontal axis.
12. The web guiding apparatus recited in claim 8 further comprising a horizontally aligned first compensator roll upstream of the first angle bar for guiding the first web in a horizontal orientation to the first angle bar, the first angle bar configured to reorient the first web to a vertical orientation.
13. The web guiding apparatus recited in claim 12 further comprising a horizontally aligned second compensator roll upstream of the second angle bar for guiding the second web in a horizontal orientation to the second angle bar, the second angle bar configured to reorient the second web to a vertical orientation.
14. The web guiding apparatus recited in claim 13 further comprising a pair of vertically aligned gather rolls downstream of the first and second angle bars for merging the vertically oriented first and second webs.
15. The web guiding apparatus recited in claim 14 further comprising a horizontally aligned former downstream of the gather rolls for longitudinally folding the merged first and second webs.
