Abstract
An internal tool for bending a strip passing in a strip-travel direction into a tube has a support juxtaposable with a face of the passing strip, at least two roller holders pivotal on the support about respective offset holder pivot axes generally parallel to the strip-travel direction, and respective rollers carried in the holders and rotatable about respective roller axes generally perpendicular to the respective holder axes.

An internal tool for bending a strip passing in a strip-travel direction into a tube, the tool comprising:
- a support juxtaposable with a face of the passing strip;
- at least two roller holders pivotal on the support about respective offset holder pivot axes generally parallel to the strip-travel direction;
- respective side rollers carried in the holders and rotatable about respective roller axes generally perpendicular to the respective holder axes and each perpendicularly intersecting the respective holder pivot axis, the holder pivot axes extending through the rollers generally at the respective roller axes;
- and
- a middle roller generally lying on the plane and rotatable about an axis generally perpendicular to the plane.
An internal tool for bending a strip passing in a strip-travel direction into a tube, the tool comprising:
- a support juxtaposable with a face of the passing strip;
- at least two roller holders pivotal on the support about respective offset holder pivot axes generally parallel to the strip-travel direction;
- respective side rollers carried in the holders and rotatable about respective roller axes generally perpendicular to the respective holder axes, the holder pivot axes extending through the rollers generally at the respective roller axes;
- a middle roller generally lying on the plane and rotatable about an axis generally perpendicular to the plane;
- and
- means coupling the holders together for synchronous movement about the respective pivot axes.
An internal tool for bending a strip passing in a strip-travel direction into a tube, the tool comprising:
- a support juxtaposable with a face of the passing strip;
- at least two roller holders pivotal on the support about respective offset holder pivot axes generally parallel to the strip-travel direction;
- and
- respective rollers carried in the holders and rotatable about respective roller axes generally perpendicular to the respective holder axes, the holder pivot axes extending through the rollers generally at the respective roller axes, the rollers including two side rollers symmetrically flanking a central plane substantially parallel to the strip-travel direction and generally bisecting the strip the rollers and a middle roller generally lying on the plane and rotatable about an axis generally perpendicular to the plane.
An internal tool for bending a strip passing in a strip-travel direction into a tube, the tool comprising:
- a support juxtaposable with a face of the passing strip;
- at least two roller holders on the support;
- respective side rollers carried in the holders and rotatable thereon about respective roller axes;
- means pivotally supporting the holders on the support about respective offset holder pivot axes generally parallel to the strip-travel direction and generally perpendicular to the respective roller axes such that, as the strip passes in the direction in engagement with the side rollers, the side rollers can move angularly freely about the respective holder axes;
- and
- a middle roller generally lying on the plane and rotatable about an axis generally perpendicular to the plane.
