Abstract
Invenţia se referă la domeniul producerii ţevilor de masă plastică turnate prin centrifugare şi este destinată fabricării ţevilor armate cu fibre şi nisip.Pentru evitarea impreciziilor în distribuirea materialului, ele fiind inevitabile la fabricarea ţevilor de masă plastică prin procese centrifuge cu ajutorul instalaţiilor cunoscute, se propune un procedeu nou şi o instalaţie pentru realizarea procedeului. Ea conţine, cel puţin, două tipare (1) şi un cărucior de injectare (12) cu braţ de încărcare (11), mobil în două direcţii perpendiculare între ele. Noutatea constă în aceea că căruciorul este montat pe un şasiu (9), deplasându-se perpendicular cu axa tiparelor (10) pe podeaua (6) clădirii, şi se poate deplasa pe şasiu perpendicular cu direcţia deplasării acestuia din urmă, căruciorul este dotat cu un buncăr de lucru pentru nisip cu o capacitate relativ mică, unit prin primul furtun (19) cu buncărul mare (20), din care cu ajutorul aerului comprimat cel dintâi buncăr se umple practic neîntrerupt, ambele buncăre fiind utilate cu traductoare de greutate. Aceste traductoare de greutate sunt unite cu un aparat de calcul şi comandă (30), care dirijează debitarea nisipului, răşinii şi fibrelor de sticlă conform unui program individual pentru fiecare construcţie a ţevii.Rezultatul tehnic al invenţiei constă în asigurarea densităţii uniforme a distribuirii nisipului în peretele ţevii.
