Abstract

Inventia se refera la un dispozitiv pneumatic pentru deplasarea semifabricatului la laminor pas de pelerin, fiind alcatuit dintr-un piston pentru comprimarea dupa dorinta a aerului în vederea aducerii între cilindrii de laminare a semifabricatului introdus pe un dorn de laminare. Camera de comprimare este în legatura atât cu spatiul cilindrului în care se poate deplasa un piston al unei pompe de comprimare cât si cu spatiul în care se poate deplasa un piston pe care este fixat dornul de laminare.
