Process for manufacturing semi-finished products

A process for continuous manufacturing of semi-finished products comprising at least one electronic device communicating by radiofrequency positioned between two strips of elastomeric material, each of the strips being extruded, the process comprising:

• extruding a first strip of elastomeric material;
• depositing the at least one electronic device on the first strip;
• extruding a second strip of elastomeric material and depositing it on the first strip;
• exerting a force on the second strip;
• cutting the first and second strips comprising the at least one electronic device;
• and then storing the cut-out strips,
• wherein each of the strips of elastomeric material is hot-extruded,
• wherein the at least one electronic device is held in place on the first strip in a longitudinal direction by a means for holding in place, and
• wherein the first strip and/or the second strip comprises a continuous groove for receiving the at least one electronic device, the continuous groove extending in the longitudinal direction of the first strip and/or of the second strip.
