ABSTRACT:
A convector for heating buildings consisting of horizontal convector modules spaced a distance apart, one above the other. Each convector module has heat-conducting tubes, onto which are forced lamella bodies, the side lugs of said lamella bodies being bent in such manner that they are parallel with the tubes. At the front and back of each convector module is attached a cover plate which is bent around the upper and lower edges of the bent side lugs. Preferably, the lamella body in its unbent position is of H-form. A tool for manufacturing the convector modules has a movable cam member for picking up and advancing the lamella bodies and rollers for bending the side lugs.
