The timber specimen was rectangular prism 120x160x280 [mm.sup.3], with six screws driven perpendicularly to the timber grain, in pre-bored holes, in distances of at least 60 mm (6d) between screw axes
. The penetration length of fasteners into the wood was approx 50 mm (8d).
There is also little information on the evolution of methyl methacrylate grafting within and along screw axes. We seek to develop equivalent experiments and kinetic modeling for methyl methacrylate in our reaction system.
The screw diameter is 30 mm, the distance of two screw axes 26 mm, and an active barrel length is 975 mm (L/D = 32.5).
Samples were removed at seven different positions along the screw axes.
Besides the work of Kim and White  there has been little information on evolution of maleic anhydride grafting and along the screw axes. We will also elucidate the grafting reaction evolution within and along the entire twin-screw extruder.
The screw diameter is 30 mm, the distance between the two screw axes 26 mm, and an active barrel length is 975 mm (L / D = 32.5).
The screw diameter is 30 mm, the distance of the two screw axes
is 26 mm, and the active barrel length is 975 mm (L/D = 32.5).
Cross sections I and II are the cross sections perpendicular to the screw axes
across the mid-point of the side gap and across the mid-point of the calendar gap as shown in Fig.
If the distance between the screw axes is less that the diameter at the tip of the screw flight, then one screw intermeshes with the other and thus provides an intermeshing twin-screw extruder.
The cross section of the screws in a plane that winds along the helical path and that is at an angle of [Theta], the screw helix angle, to the plane perpendicular to the screw axes is shown in Fig.
