Title:
浮き上がる駆動ローラを有するパイプを加工するデバイス
Document Type and Number:
Japanese Patent JP2012519601
Kind Code:
A
Abstract:
A device for processing a pipe has a bearing plate slidably mounted on a support plate. A drive roller, engageable with an inner surface of a pipe, is mounted on the bearing plate and rotates about an axis substantially parallel to the longitudinal axis of the pipe. Support rollers, mounted on the support plate, engage and support the pipe against the drive roller. Springs are positioned in contact with the support plate and the bearing plate and bias the drive roller into engagement with the pipe. Variations in pipe wall thickness are compensated for by sliding motion of the bearing plate relatively to the support plate as the drive roller rotates and the pipe and the device move relatively to one another.
