ABSTRACT:
This invention provides a bending roll apparatus capable of preventing barrel-like deformation of a pipe occurring during a roll bending work and of manufacturing a small diameter elongated pipe. In an apparatus for manufacturing a pipe by pushing rolls to a core roll, feeding a metal sheet to their contact portions and performing a bending work, the bending roll apparatus comprises a core roll formed of a metal and a plurality of push rolls having a surface portion thereof formed of an elastic material and disposed around the core roll. The invention further provides, in a bending roll apparatus, a core roll formed of a metal, a plurality of push rolls formed of a metal and disposed around the core roll, and holding the core roll when a metal sheet is bent, and a guide belt formed of an elastic material, interposed between the core roll and each of the push rolls, contacting on a core roll surface on a side opposite to an entry side of the metal sheet and driven in synchronism with the core roll.
