Abstract

A shower device for a papermaking machine is provided which includes a longitudinally extending hollow member having an inlet end adapted for connection to a pressurized water source. A slot extends longitudinally along at least a portion of the hollow member. The slot includes opposing edges and a strip of material is slideably engageable with the hollow member so that the hollow member is substantially sealed along the edges of the slot when the strip is installed. The strip of material includes a plurality of spaced apart shower nozzles. This allows a plurality of shower nozzles on a papermaking machine to be quickly and easily replaced by slidably removing the nozzle strip from the slot and slidably inserting a replacement strip of nozzles into the slot.

Claims (24)

1. A shower device for a papermaking machine, comprising:

a longitudinally extending hollow member having an inlet end adapted for connection to a pressurized water source;

a slot extending longitudinally along at least a portion of the hollow member, the slot having opposed edges; and

a strip of material slidably engageable with and disengagable from the hollow member so that the hollow member is substantially sealed along the edges of the slot when the strip is installed, the strip of material including a plurality of spaced apart shower nozzles.

2. The shower device of claim 1 , wherein the hollow member is a pipe, and the slot is formed by a slit extending longitudinally through a sidewall of the pipe.

3. The shower device of claim 1 , wherein a strip holder is at least one of formed in the hollow member along the edges of the slot or attached to the hollow member along the edges of the slot.

4. The shower device of claim 3 , wherein the strip holder is formed in the hollow member and includes grooves that extend generally parallel to the edges of the slot.

5. The shower device of claim 3 , wherein the strip holder includes a fitting which is attached to the hollow member along the slot, the fitting having generally parallel grooves for receiving the strip.

6. The show device of claim 3 , wherein the strip holder is made of an elastically deformable material.

7. The shower device of claim 3 , wherein the strip of material is made of an elastically deformable material.

8. The shower device of claim 7 wherein the strip of material further includes a reinforcements means.

9. The shower device of claim 1 , wherein the shower nozzles are generally linearly arranged an are generally uniformly spaced apart.

10. The shower device of claim 1 , wherein the strip is made of an elastically deformable material.

11. The shower device of claim 1 , wherein the shower nozzles are inserted into the strip.

12. The shower device of claim 1 , wherein the shower nozzles are formed in the strip.

13. The shower device of claim 1 , wherein the shower nozzles are removably connected to the strip.

14. The shower device of claim 1 , wherein the strip is formed of a polymeric material.

15. The shower device of claim 14 wherein the strip of material further includes a reinforcement means.

16. The shower device of claim 1 , further comprising a movable brush located in the hollow in member, the brush being mounted for movement over an inlet side of the nozzles.

17. The shower device of claim 1 , wherein the slot extends longitudinally along generally an entire length of the hollow member, and the strip extends along generally the entire length of the hollow member.

18. A method of replacing a plurality of shower nozzles on a papermaking machine, comprising:

slidably removing a nozzle strip including a plurality of spaced apart nozzles from a slot extending longitudinally along at least a portion of a hollow member having an inlet end adapted for connection to a pressurized water source; and

slidably inserting a replacement strip of spaced apart nozzles into the slot.

19. The method of claim 18 , further comprising installing a sealing cap on an end of the hollow member to create a fluid tight seal.
