Abstract
Abstract A bundling apparatus for flattened tube sections coming from a tube making machine comprising a first conveyor for depositing the tube sections from the machine thereon in an overlapping scale formation followed by a continuously movable second conveyor for transporting the tube sections after they have been formed into bundles. A suction beam engages and holds the lowermost tube section of each bundle on the second conveyor and is adapted to have its suction effect interrupted after each bundle has been formed with a predetermined number of tube sections. A substantially vertical abutment plate for the tube sections has its bottom edge disposed immediately above the conveying run of the second conveyor during formation of each bundle and is adapted to be raised after the formation of each bundle.
