  • the ends 2, 3 of the belt piece 1 shown in figure 3 are configured so that their restraining can be realized only according to a direction orthogonal to their extension surface S; such ends 2, 3 are approached but they are disposed at different heights so that their respective complementary profiles 4, 5, if viewed in plan view (not shown), mutually match; their removable restraining being for example realized by lowering the second end 3 to the first end 2, see figure 4.
  • This restraining results stable in longitudinal and transverse direction with respect to the extension direction of the serrated looped belt 10, thus obtained.
  • the restrained ends 2, 3 of the serrated closed looped belt 10 can be mutually fixed by means of local melting of corresponding thermoplastic material; figure 5 shows therefore the serrated closed looped belt 10 of figure 4 after fixing by melting the ends 2, 3 (shown in broken lines in figure 5).

  • the interaction stabilizing between each couple of first 6 and second portion 7 individually contributes to provide a total resistant force opposing and compensating the longitudinal traction effort, so as to prevent the respective ends 2, 3 from sliding in longitudinal direction.
  • Each couple thus defined can oppose a maximum resistant force value which depends on the configuration (form and dimensions) of the contact surfaces of the corresponding first 6 and second 7 portion; these contact surfaces extend according to the extension components which are transverse to the longitudinal axis of the looped belt 10.
  • the maximum value of total resistant force possible, opposed by restraining the ends 2, 3 to a traction effort in longitudinal direction depends on the total interaction of the plurality of the first 6 and second portion 7.

  • the junction area 40 (or coupling region) of the ends 2, 3 (for example with inclination angles ⁇ , as described, greater than 30 degrees) extends in transverse direction, namely it is distributed in the longitudinal direction of the looped belt 10; as a consequence the length of the part of the looped belt 10 comprising the junction area 40 increases and the average resistance to traction of each transverse portion of this part which winds around the pulleys increases as well. On the whole, it can be considered that the total resistance to traction of the looped belt 10 advantageously increases; such increase being correlated to the angle ⁇ value.

  • the resistance to traction efforts of the looped belt 10 is instead mainly applied by restraining the ends 2, 3, as above precised, by means of the interaction between the contact surfaces of the first 6 and second portions 7 of complementary profiles 4, 5.

Moreover, the production costs of the belt piece thus obtained are relatively reduced with respect to the achieved advantages.
  • Another advantage of the present invention lies in having defined a method for obtaining a closed looped belt employing the new belt piece of the above-described type as a starting element, which belt can be employed for the transport of articles and/or for power transmissions and which has better characteristics of resistance to longitudinal traction efforts with respect to belts of known type in the field of interest.

Therefore, the above-described advantages show how the belt piece and the method for obtaining a closed looped belt employing the same belt piece as a starting element, both being objects of the present invention, satisfy the objects fixed in advance and brilliantly solve the disadvantages peculiar to the solutions of known type.
  • Another advantage of the present invention lies in having defined a belt piece, which depending on the traction/compression efforts, the corresponding looped belt is subjected to, allows to design the configuration and the development of its respective coupling ends 2, 3 according to the application needs.
