Abstract
Procedeu de fabricare a unui bloc dintr-un copoliester polimer elastomer de o lungime axiala data, destinat realizarii unui arc de compresiune, ce nu sufera deformatii permanente importante la supunerea la o forta axiala capabila sa-l comprime într-omasura mai mare decât cea care ar rezulta printr-o deformare permanenta a lungimii sale axiale, caracterizat prin aceea ca, în scopul sporirii durabilitatii arcului, consta din aplicarea pe numitul bloc a unei forte axiale suficiente pentru a-l comprima cu mai mult de treizeci de procente din numita lungime axiala data, urmata de îndepartarea acestei forte axiale de pe bloc.A process for manufacturing a block of an elastomeric polymer copolyester of a given axial length designed to produce a compression spring which does not suffer significant permanent deflection upon subjection to an axial force capable of compressing it to a greater extent than that which would result in a permanent deformation of its axial length, characterized in that in order to increase the durability of the spring it consists in applying on said block a sufficient axial force to compress it with more than thirty percent of said given axial length, followed by the removal of this axial force from the block.
