Abstract: A control device on a packaging machine for single and multiple packaging of articles of clothing hanging on coat hangers and to be jacketed and welded in a tube film of plastics material in which in the region of the running path of the articles of clothing between the feed screw and the packaging suspension device there are arranged a singler and a stopper arranged at a distance therefrom as well as a scanner registering the number of clothing articles to be packaged by preselection with magnetic scanning, by color scanning or by distance scanning and controlling the singler and stopper for packaging preparation and release.

Abstract: A process is provided for manufacturing an exhaust manifold. The manifold comprises at least one stamp formed inlet flange, a stamp formed sheet metal inner shell and a stamp formed sheet metal outer shell. The inner shell and outer shell are configured to define an exhaust chamber therebetween. Each inlet flange is stamp formed to define at least one exhaust port extending entirely therethrough, with each exhaust port including a stamp formed projection extending continuously thereabout from one surface of the inlet flange. The inner shell is stamp formed to define an inlet aperture for each exhaust port. The inner shell is projection welded to the inlet flange such that the projections stamp formed therein define the weldments. The outer shell then is welded to the inner shell to define the exhaust chamber of the manifold. An outlet tube may be secured to an outlet aperture of the outer shell.
