Non-trapped stripper belt
View Patent ↗A device for transporting a flat product includes a rotating transport cylinder and a continuous stripper belt. The rotating transport cylinder defines an axis of rotation and is configured to guide the flat product at a circumference of the cylinder over a first angle of rotation of the cylinder. The continuous stripper belt is disposed between the flat product and the axis of rotation over a second angle of rotation of the cylinder and is configured to guide the flat product away from the cylinder so as to strip the flat product from the cylinder. The stripper belt follows a continuous path that does not circumscribe the axis of rotation. In addition, a method for transporting a flat product includes guiding the flat product at a circumference of a rotating transport cylinder defining an axis of rotation over a first angle of rotation of the cylinder and stripping the flat product from the transport cylinder using a continuous stripper belt that follows a continuous path not circumscribing the axis of rotation.
1. A device for transporting a flat product, the device comprising:
a rotating transport cylinder defining an axis of rotation and configured to guide the flat product at a circumference of the cylinder over a first angle of rotation of the cylinder; and
a continuous stripper belt disposed between the flat product and the axis of rotation over a second angle of rotation of the cylinder and configured to guide the flat product away from the cylinder so as to strip the flat product from the cylinder, the stripper belt following a continuous path that does not circumscribe the axis of rotation.
2. The device as recited in claim 1 wherein the transport cylinder includes a gripper configured to releaseably grip the flat product during the first angle of rotation.
3. The device as recited in claim 1 wherein the second angle of rotation includes the first angle of rotation.
4. The device as recited in claim 1 further comprising a plurality of belt guides configured to guide the stripper belt along the continuous path.
5. The device as recited in claim 1 wherein the continuous path surrounds at least one half of the circumference of the cylinder.
6. The device as recited in claim 1 wherein the cylinder defines a groove in the circumference and wherein the stripper belt is disposed in the groove over at least part of the continuous path.
7. The device as recited in claim 1 further comprising a stripper roller having a second axis of rotation parallel to the axis of rotation of the transport cylinder, the stripper roller disposed adjacent to the transport cylinder.
8. The device as recited in claim 1 further comprising a second continuous stripper belt disposed between the flat product and the axis of rotation over a third angle of rotation of the cylinder and configured to guide the flat product away from the cylinder so as to strip the flat product from the cylinder, the second stripper belt following a second continuous path that does not circumscribe the axis of rotation.
9. The device as recited in claim 1 wherein the stripper belt has a round cross-section.
10. A method for transporting a flat product, the method comprising:
guiding the flat product at a circumference of a rotating transport cylinder over a first angle of rotation of the cylinder, the cylinder defining an axis of rotation; and
stripping the flat product from the transport cylinder using a continuous stripper belt disposed between the flat product and the axis of rotation over a second angle of rotation of the cylinder, the stripper belt configured to guide the flat product away from the cylinder so as to strip the flat product from the cylinder, the stripper belt following a continuous path that does not circumscribe the axis of rotation.
11. The method as recited in claim 10 further comprising gripping the flat product at a first location in the first angle of rotation and releasing the flat product at a second location in the angle of rotation.
12. The method as recited in claim 10 wherein the second angle of rotation includes the first angle of rotation.
13. The method as recited in claim 10 further comprising guiding the continuous stripper belt along the continuous path using a plurality of belt guides.
14. The method as recited in claim 10 wherein the continuous path surrounds at least one half of the circumference of the cylinder.
15. The method as recited in claim 10 wherein the stripper belt is disposed in a groove defined in the circumference of the cylinder and wherein the stripper belt is disposed in the groove over at least part of the continuous path.
16. The method as recited in claim 10 further comprising guiding the continuous path of the stripper belt from the circumference of the cylinder using a stripper roller having a second axis of rotation parallel to the axis of rotation of the transport cylinder and disposed adjacent to the transport cylinder.
17. The method as recited in claim 10 wherein the stripping is performed using a second continuous stripper belt in conjunction with the continuous stripper belt, the second stripper belt disposed between the flat product and the axis of rotation over a third angle of rotation of the cylinder, the second stripper belt configured to guide the flat product away from the cylinder so as to strip the flat product from the cylinder, the second stripper belt following a second continuous path that does not circumscribe the axis of rotation.
18. The method as recited in claim 10 wherein the stripper belt has a round cross-section.
