1. A conveyor belt, for conveying plate elements along a longitudinal direction, in a machine for converting the plate elements, the conveyor belt comprising: a belt body that comprises longitudinal edges, joining edges including a first joining edge and a second joining edge, and a support surface
1. A conveyor belt, for conveying plate elements along a longitudinal direction, in a machine for converting the plate elements, the conveyor belt comprising: a belt body that comprises longitudinal edges, joining edges including a first joining edge and a second joining edge, and a support surface shaped for supporting the plate elements, andat least one assembly member arranged to join the first joining edge with the second joining edge, the least one assembly member extending in a direction of assembly which is oblique to the longitudinal direction,wherein the belt body has a plurality of perforations disposed for obtaining a vacuum on the support surface to immobilize the plate elements on the belt body, andwherein perforations of the plurality of perforations are provided in immediate proximity to the at least one assembly member such that a shortest distance between a first perforation of the plurality of perforations formed at the first joining edge and a second perforation of the plurality of perforations formed at the second joining edge is equal to a shortest distance between two perforations of the plurality of perforations formed in the belt body. 2. A conveyor belt according to claim 1, wherein the direction of assembly and the longitudinal direction define an acute angle of assembly substantially between 75° and 88°. 3. A conveyor belt according to claim 2, wherein the acute angle is between 85° and 87°. 4. A conveyor belt according to claim 2, wherein the acute angle is equal to 86°. 5. A conveyor belt according to claim 1, wherein the direction of assembly is straight. 6. A conveyor belt according to claim 1, wherein the perforations are distributed in several lines. 7. A conveyer belt according to claim 6, wherein the lines are substantially parallel to the direction of assembly. 8. A conveyor belt according to claim 1, wherein the perforations are distributed in a central region extending between the longitudinal edges and having a width, measured perpendicular to the longitudinal edges, which represents between 30% and 70% of the width of the belt body. 9. A conveyor belt according to claim 1, wherein perforations of the plurality of perforations are distributed over three zones, a central zone having a high density of perforations, and two lateral zones on either side of the central zone having a lower density of perforations. 10. A conveyor belt according to claim 1, wherein the belt body has at least two holes, preferably positioned close to a respective longitudinal edge, each hole being designed to be passed through by a pin for holding the belt body in place during assembly of the assembly member. 11. A conveyor belt according to claim 1, wherein the belt body has a rolling surface designed to interact with drive members to drive the conveyor belt, the assembly member being positioned between the support surface and the rolling surface, such that the assembly member is set back from the support surface and from the rolling surface. 12. A conveyor belt according to claim 1, wherein the belt body is comprised of a polymer and/or elastomer. 13. A machine for converting elements comprising: at least one conveyor belt according to claim 1, mounted around a chamber capable of generating a vacuum on the support surface. 14. A machine according to claim 13, wherein the machine is a printing machine. 15. A conveyor belt according to claim 1, wherein the belt body is comprised of polyester fabric with a polyurethane coating. 16. A conveyor belt, for conveying plate elements along a longitudinal direction, in a machine for converting the plate elements, the conveyor belt comprising: a belt body that comprises longitudinal edges, joining edges including a first joining edge and a second joining edge, and a support surface shaped for supporting the plate elements, andat least one assembly member arranged so as to join the first joining edge with the second joining edge, the least one assembly member extending in a direction of assembly which is oblique to the longitudinal direction,wherein the belt body has a plurality of perforations disposed for obtaining a vacuum on the support surface to immobilize the plate elements on the belt body, andwherein perforations of the plurality of perforations are distributed over three zones, a central zone having a high density of perforations, and two lateral zones on either side of the central zone having a lower density of perforations. 17. A conveyor belt according to claim 16, wherein perforations of the plurality of perforations are provided in immediate proximity to the at least one assembly member such that a shortest distance between a first perforation of the plurality of perforations formed at the first joining edge and a second perforation of the plurality of perforations formed at the second joining edge is equal to a shortest distance between two perforations of the plurality of perforations formed in the belt body.
