Abstract

1,198,790. Bending tubes. R. P. MINGORI. 25 April, 1969 [2 May, 1968], No. 21163/69. Heading B3E. Apparatus for forming intermediate bends in tubes comprises a frame which supports two interchangeable freely rotatable rollers 8 adjustably spaced apart and mounted between guideplates 9, at least one of which is removable, and a shaping attachment mounting 1, at its centre, an interchangeable shaping part 4 and at least two pivotable tube supports 6 disposed symmetrically one to each side of the shaping part 4, the assembly of the guide plates 9 and rollers 8 and the shaping attachment 1 being relatively movable. The separation of the grooved rollers 8 is selected to produce the desired lateral curves of the tube 12 while the shaping part 4 is selected to produce the desired central curve. On moving the attachment 1 towards the rollers 8, the tube is first bent into the shape shown in Fig. 4 at which point the two straight branches of the tube engage the two pivoted supports 6. Further movement of attachment 1 towards the rollers 8 produces the shape as shown in Fig. 5 where the axes of the two straight parts of the tube are in alignment.
