through the head openings again fig4 b shows the spray pattern attributable to the action of the main head in the fig4 embodiment the booster head is beneath the main head and jets of stock forward to intercept the jets from the main head again the purpose of the booster head is to break up the possible micro agglomerations and to speed the spray to every possible specification requirement fig5 is a top view showing the main head when the main spray ms and the booster spray bs are showing the interception of these two streams at breakpoint bp at the margins of the belt along its edges there are imposed air curtains as shown for the purpose of limiting the edgewise expanse of the main head flow this serves to keep the stock on the belt aside from air the curtain may be a flow of water or even stock from the booster line as shown the no box system will not be affected by the variation in the stock consistency or variation of the fiber dimension and allows even higher machine speeds than given here or higher than the speed of any existing paper machine the no box system can also work on the basis that the no box spray head is moving upon the wire and the wire itself stays stationary this would be the opposite to the traditional paper machines an example of this arrangement is pictured in fig6 wherein the stock is delivered from a rigid stock line 101.
