Method and apparatus for transporting a sheet from a dryer to a reel
View Patent ↗A system and method for transferring a continuously advancing paper web from a dryer to a reel section is provided. The system includes a first fabric defining a first moving conveyor. The first fabric may be a permeable fabric, which is positioned downstream from the dryer. A second fabric, which may also be permeable and defines a second moving conveyor, is also included. The first moving conveyor overlaps the second moving conveyor for a predetermined distance, and the first and second moving conveyors are configured to receive the paper web between the conveyors. A vacuum device is rotatably disposed against the first moving conveyor, and the dryer and the vacuum device are disposed relative to each other to form an open draw. The vacuum device is configured to produce a vacuum to attract the web to the first fabric for transferring the advancing web into the predetermined distance where the first and second conveyors overlap.
1. A system for transferring a continuously advancing tissue web from a dryer to a reel section comprising:
a first fabric defining a first moving conveyor with a bottom surface, the first fabric being positioned downstream from the dryer;
a second fabric defining a second moving conveyor with a top surface, the first moving conveyor overlapping the second moving conveyor for a predetermined distance, the first and second moving conveyors being configured to receive a creped tissue web between the conveyors; and
a vacuum device rotatably disposed against the first moving conveyor, the dryer and the vacuum device disposed relative to each other to form an open draw therebetween, the vacuum device configured to produce a suction to pull the creped tissue web to the bottom surface of the first fabric across the open draw for transferring the advancing tissue web into the predetermined distance where the first and second conveyors overlap.
2. The system of claim 1 , wherein the open draw defines a distance of between 4 inches to about 48 inches.
3. The system of claim 1 , wherein the open draw defines a distance of between 10 inches to about 30 inches.
4. The system of claim 1 , further comprising holding means for holding the web against the second moving conveyor.
5. The system of claim 4 , wherein the holding means for holding the web is a vacuum box.
6. The system of claim 5 , wherein the vacuum box is configured to produce a vacuum pressure of between 0.1 inches of water to about 3.0 inches of water.
7. The system of claim 4 , wherein the holding means for holding the web is a blow box.
8. The system of claim 4 , wherein the holding means for holding the web is a static induction device.
9. The system of claim 1 , further comprising a creping station, the creping station configured to separate and deflect the web from the dryer to the first fabric.
10. A system for transporting an advancing tissue web comprising:
a pick-up fabric conveyor defining a bottom surface, the bottom surface configured to receive and transport the tissue web across an open draw between a dryer and the pick-up fabric conveyor;
a delivery conveyor defining a top surface disposed in partial moving engagement with the bottom surface of the pick-up fabric conveyor along a length of each of the delivery and pick-up fabric conveyors, the delivery and pick-up fabric conveyors being configured to receive the tissue web between the conveyors; and
transferring means for transferring the tissue web from the draw to the bottom surface of the pick-up fabric conveyor, the transferring means disposed against the pick-up fabric conveyor and at least partially between the dryer and the delivery conveyor, the transferring means cooperative with the bottom surface of the pick-up fabric conveyor for transferring the advancing tissue web from the pick-up fabric conveyor to between the conveyors in the direction of a reel assembly.
