A device for supporting and guiding supplying lines used with a digging tool on a drilling machine is described. The device comprises a support branch, formed by a plurality of spacers, adjacent to one another in which a rope or tie-rod is inserted in a housing comprised in the spacers, a supplying pipe for the supplying line and a crosspiece comprising a seat adapted to support the supplying pipe. Each pair of adjacent spacers comprises retaining means. Each retaining means comprises a retaining element, associated to a first spacer of a pair of adjacent spacers, and a slot having a shape substantially matching the shape of the retaining element, associated to a second spacer of the pair of adjacent spacers. A retaining element, during use, engages with a slot allowing relative axial movement, in the longitudinal direction of the rope, of a predetermined amount.

A cord package supporting device for supporting a cord package wound with a cord, such as for an elastic joint disk for connecting two shaft portions, is disclosed. The cord package includes two opposite arcuate cord regions and two tangential cord regions that connect the arcuate cord regions to each other and extend parallel to each other. In embodiments, the cord package supporting device includes a first redirecting portion and a second redirecting portion, about which in each case one arcuate cord region of the cord package is guided. In embodiments, the two redirecting portions are integrally connected to each other via a web. An elastic joint disk and a method for producing an elastic joint disk are also disclosed.
