Abstract: Support and guiding apparatus (3) for feeder lines comprising at least a feeding tube (5) for a digging device (2), said support and guiding apparatus (3) comprising at least a support branch (4) and a plurality of transverse connecting elements or crosspieces (40) connected to said at least a support branch (4), wherein said at least a support branch (4) comprises: a single flexible traction element (6), defining a longitudinal axis (X) said flexible traction element (6) having two opposite end sections (7) and an intermediate section (8) interposed between said end sections (7), said flexible traction element (6) having, at least in the intermediate section (8), a cross section S in a plane YZ perpendicular with respect to said longitudinal axis X, said cross section S being substantially constant all along the length of said at least an intermediate section (8) along the longitudinal axis (X), said cross section S having a width B extending in the direction of the axis Y and a thickness or height H extending in the direction of the axis Z where said width B is greater than said thickness or height H; a plurality of spacer elements (30,39) coupled to said single flexible traction element (6), each one of said spacer elements (30) having a first seat (33) housing the flexible traction element and which is crossed by the flexible traction element, said first seat (33) being shaped in such a way as to orient said flexible traction element (6) along a lying plane XY, and to prevent rotation of the spacer element (30, 39) around the longitudinal axis X, each one of said spacer elements (30,39) being arranged to allow the rotation of the support branch (4) around a rotation axis parallel with respect to said axis Y.
