Method for Spraying Trusses With a Mold and Insect Preventative Solution

Abstract

A spray box assembly including, in combination, a top spray box, a bottom spray box, the boxes being juxtapositioned to define a pathway therebetween, at least one spray assembly positioned within at least one of the boxes and a supply assembly for supplying a treating solution to the spray assembly to coat product with the treating solution as the product is fed through the pathway and also including a method of coating a product with a treating solution, comprising the steps of feeding the product into a pathway between top spray box and a bottom spray box and spraying the treating solution within at least one of the boxes about the pathway to coat the product with the treating solution as the product is fed through the pathway.

1 . A method of coating a product with a treating solution, comprising the steps of feeding the product into a pathway between top spray box and a bottom spray box and spraying the treating solution within at least one of the boxes about the pathway to coat the product with the treating solution as the product is fed through the pathway. 
   
   
       2 . The method according to  claim 1 , wherein the product being treated comprises a wood truss. 
   
   
       3 . The method according to  claim 1 , further including the step of pressing brackets into the joints of the wood truss before passing into the pathway. 
   
   
       4 . The method according to  claim 1 , further including the step of discharging the wood truss from the pathway onto a roller table. 
   
   
       5 . The method according to  claim 1 , wherein the step of spraying the treating solution within at least one of the boxes about the pathway to coat the product with the treating solution as the product is fed through the pathway comprises the step of spraying the treating solution from at least one of spray assembly. 
   
   
       6 . The method according to  claim 1 , wherein the step of spraying the treating solution from at least one of spray assembly comprises spraying the treating solution from an array of spray heads fluidly connected to spray lines extending along the length one or both of the spray box. 
   
   
       7 . The method according to  claim 1 , further comprises the step of brushing excess treating solution from at least a portion of the wood truss before being discharged from the pathway. 
   
   
       8 . The method according to  claim 1 , wherein the step of brushing excess treating solution from at least a portion of the wood truss before being discharged from the pathway comprises brushing the wood truss along its entire length. 
   
   
       9 . The method according to  claim 1 , further comprising the step of draining excess treating solution from the spray boxes and recirculating the treating solution. 
   
   
       10 . The method according to  claim 1 , further comprising the step of storing the excess treating solution drained from the spray boxes before recirculating the treating solution.
