Abstract
ABSTRACT OF THE DISCLOSURE
A blow box for use beneath a pair of carrier rolls or a roll winder for a web.
The blow box disposed beneath the carrier rolls has first and second side walls generally sealed respectively at each of the carrier rolls. The paper web passesbeneath one of the carrier rolls and up between the rolls. The web may tear and the paper web then drops into the blow box. A connecting wall on the blow box between the side walls thereof and above the base receives the paper falling thereon rather than the paper falling into the blow box. The connecting wall may be inclined to direct the falling paper toward a side wall where and opening is provided enabling the moving of the paper. The connecting wall may be perforated and the air flow into the blow box is beneath the perforated wall so that the air flow through the wall cooperates in moving the falling paper along the connecting wall. As a result, the waste paper can be removed quickly and easily.

Claims (16)
1. A blow box for a carrier-roll winding machine wherein the winding machine includes first and second neighboring carrier rolls which are adapted to support a reel thereon on which a web is wound, the carrierrolls being positioned near each other;
the blow box comprising:
respective first and second side walls beneath the first and second carrier rolls, one of the side walls being generally sealed at each of the carrier rolls, and the side walls being spaced apart to define an open area in the blow box; a base of the blow box joining the side walls;
a connection for feeding air into the blow box; and a connecting wall in the blow box above the base, extending between the side walls and positioned for receiving thereon paper which falls into the blow box, as when the web tears.
the blow box comprising:
respective first and second side walls beneath the first and second carrier rolls, one of the side walls being generally sealed at each of the carrier rolls, and the side walls being spaced apart to define an open area in the blow box; a base of the blow box joining the side walls;
a connection for feeding air into the blow box; and a connecting wall in the blow box above the base, extending between the side walls and positioned for receiving thereon paper which falls into the blow box, as when the web tears.
2. The blow box of claim 1, wherein the side walls are fixed in position with respect to each other.
3. The blow box claim 1, wherein the connecting wall is fastened to and between each of the side walls.
4. The blow box of claim 3, further comprising reinforcing ribs extending between the side walls in addition to the connecting wall for reinforcing the blow box.
5. The blow box of claim 1, further comprising an opening in one of the side walls at the connecting wall providing access onto the blow box.
6. The blow box of claim 5, further comprising a device for selectively opening and closing the opening in the one side wall.
7. The blow box of claim 6, wherein the device comprises a pivotable flap supported to the one side wall and pivotable between the open and closed positions.
8. The blow box of claim 5, wherein the connecting wall is generally inclined between the sidewalls downward toward the opening, so that residual paper on the connecting wall may slide along the inclined connecting wall.
9. The blow box of claim 8, wherein the connection for feeding air into the blow box is disposed beneath the connecting wall, whereby air entering the blow box may pass the connecting wall.
10. The blow box of claim 9, wherein the incline of the connecting wall is so directed and the opening in the side wall is so placed that paper on the connecting wall may slide toward the opening in the side wall.
11. The blow box of claim 1, wherein the connecting wall is inclined toward one of the side walls such that paper on the connecting wall may slide along the inclined connecting wall.
12. The blow box of claim 11, further comprising an opening in one of the side walls at the connecting wall providing access into the blow box, andwherein the incline is so directed and the opening in the one side wall is so placed that the paper slides toward the opening in the one side wall.
13. The blow box of claim 12, further comprising perforations defined in the connecting wall through which air may pass.
14. The blow box of claim 13, wherein the connection for feeding air into the blow box is disposed beneath the connecting wall, whereby air entering the blow box may pass through the perforations of the connecting box.
15. The blow box of claim 1, further comprising perforations defined in the connecting wall through which air may pass.
16. The blow box of claim 15, wherein the connection for feeding air into the bow box is disposed beneath the connecting wall, whereby air entering the blow box may pass through the perforations of the connecting wall.
