2. Check saveall for tears or holes in covering.
3. Check buttons in showers for burrs and rough spots causing a build-up of lumps
(a) plugged showers in headbox will give streaks in sheet on the forming fabric.
(b) if parts of the nozzles are plugged, flow in the shower pipe is reduced.
(c) if shower is not fitted with an overflow, slime growth can occur.
