Painting line for metal objects

A painting line for metal objects, comprising a base for affixing objects (2) at a space from one another on said base, paint spreading members (5) for spreading paint on said objects affixed on said base, and heating elements (6) for fixing the paint on the objects prior to detaching these from the base, characterized in that the base is a magnetic conveyor (1) provided with a feeder (7) for organizing objects (2) in one or more adjacent individual rows to join on the magnetic conveyor and a thin sheet (8) positioned between the magnetic conveyor (1) and the objects (2) such that the objects are attracted from each row to the sheet (8) by the magnetic conveyor (1) and move with the magnetic conveyor (1) whereby the paint spreading members (5) are positioned after the feeder (7) in the travel path of the magnetic conveyor (1) and are separated from the magnetic conveyor by the thin sheet (8), the thin sheet extending along the travel path of the magnetic conveyor for at least a distance sufficient to protect the conveyor from the paint spreading members, against which sheet the objects (2) glide due to the action of the magnetic conveyor (1) gliding against the opposite side of said sheet, and that subsequent to the heating elements (6) which are positioned along the travel path of the magnetic conveyor (1) after the paint spreading members (5), a member (9) is provided on the travel path of the painted objects (2) conveyed by the magnetic conveyor, for dropping said objects off from the magnetic conveyor (1).
