A method for obtaining a closed looped belt, usable for the transport of articles and/or for power transmissions, the belt being made from a belt piece, characterized in that it comprises the steps of:
- providing a belt piece comprising a central body (80) and two ends, a first end (2) and a second end (3), which can be connected to each other, said first and second ends (2, 3) being extendable in parallel to a longitudinal axis of said belt piece (1);
- said first and second ends having transverse dimensions smaller than transverse dimensions of the central body (80) of said belt piece (1);
- and at least at longitudinal sides (81, 82), the first and second ends (2, 3) have complementary coupling profiles (4, 5) respectively comprising at least a first portion and a second portion (6, 7), which contact each other when said ends (2, 3) are restrained with respect to each other such that the first and second portions press against each other when a longitudinal traction force is applied to said belt piece (1), closed as a loop, to prevent the first and second ends (2, 3) from sliding in the longitudinal direction;
- approaching said ends (2, 3) of said belt piece (1) in a direction comprising at least one component orthogonal to the longitudinal direction of extension of said belt piece (1), until said ends (2, 3) of said belt piece (1) are restrained with respect to each other, so as to obtain a belt (10) closed as a loop;
- and fixing said ends (2, 3) with respect to each other.
