then be passed through an oven 59 in which the binder may be cured any water remaining in the mat 53 will thus be eliminated by evaporation the mat may then be gathered onto a spool 61 for later transportation and use in a final product preparation as can be seen in fig1 water may be used to wash the screen 35 after the mat 53 is separated therefrom by moving the screenpast a plurality of spray pipes 63 the water may be taken from the drain pan 49 located below the screen in a manner to be described also the slurry water sucked through the screen and into the vacuum chamber 41 may also be delivered to the pan 49 by one or more suitable exhaust pipes 65 as illustrated since the water passing through the pipes 65 will be heavily laden with chopped glass fibers this high concentrate slurry may be passed through a pipe 67 by means of a pump 69 for delivery to one of the tanks 21 as illustrated on the other hand some of the water at the right end of the drain pan 49 as seen in fig1 may pass through a screen 73 and then pass through a pipe 75 by means of a pump 77 the fluid in pipe 75 may be delivered directly back to the pipe 31 for movement to the slurry tank 33 as the water in the drain pan 49 continues to move from right to left as seen in fig1 it may be passed through a rotating fiber screen water blaster device.
