Document Type and Number:
Japanese Patent JP2879300
Kind Code:
B2
Abstract:
An improved combination (40) counter rotating packerhead and vibrator assembly is provided. A counter rotating packerhead comprising counter rotating roller assemblies (36,37), longbottom assemblies or a combination thereof is disposed directly over an annular pneumatic vibrator (65). The coaxial drive shaft (48,49) for the counter rotating packerhead passes through the vibrator (65) thereby permitting the power transmission means to be located below, and isolated from, the vibrator (65). The vibrator is disposed below, but adjacent to, the counter rotating packerhead for faster pipe production.
