42 when the machine is in the 34 running 34 position as indicated in fig2 belt 25 is in contact with fabric 30 and prevents any leaking of the fiber slurry when the machine is in the 34 off 34 position as shown in fig3 belt 25 is not in contact with fabric 30 by reason of the fact that frame base 37 and all equipment attached thereto has been pivoted 90 degrees about shaft 41 it should be noted that belt 25 extends outwardly beyond the working edge of roll 23 so that only the edge of belt 25 touches fabric 30 and not the edge of roll 23 the deckle belt 25 as seen in fig1 and 2 has a return or inoperative portion spaced outwardly of the fabric 30 which is slightly elevated above the plane of the fabric 30 of course when a deckle belt 25 is employed on each of the side edges of fabric 30 the return portions face oppositely from each other and are disengaged from fabric 30 at all times this feature materially lengthens the life of fabric 30 and belt 25 by eliminating the abrasion that would occur if the edge of roll 23 rubbed against fabric 30 as well as belt 25 belt 25 and roll 23 are actually tilted at angle 55 about 1 degree so as to eliminate any touching of the belt to the fabric 30 except along a.
