Abstract
A shotpeening machine for helical compression springs. It comprises a spring-peening chamber accommodating shot-impelling rotors, mechanisms for accommodating and tensioning the springs, and mechanisms for loading the springs into and unloading them from the accommodating and tensioning mechanisms. The accommodating and tensioning mechanisms comprise one or two spring holders (5) that travel back and forth horizontally into the peening chamber (3) and in that the loading and unloading mechanisms are prismatic belts (6) that parallel the chamber.
