Claims9
A hairpin bender machine for simultaneously working a plurality of tubes, said machine comprising:
- a device for feeding and moving tubes to be worked and comprising a plurality of guides which define feed tracks for said tubes,
- a unit for bending said tubes,
- a cutting member configured to cut said plurality of tubes,
- a belling device to perform, alternatively to a bending operation, a belling operation on at least part of said plurality of tubes,
- wherein said belling device comprises belling elements, each suitable to be aligned with each of said tubes to cooperate with one of its ends,
- wherein said belling device is associated with movement devices and is configured to have an inactive position, in which the belling elements are positioned at a lower level than said tracks defined by the guides, and a working position, in which said belling elements are aligned with said tracks defined by said guides.
