A drift eliminator is formed from alternating curved spacers and corrugated spacer members to define tube-like passageways for the flow of air through an evaporative cooling apparatus. The formation of the corrugated blade member with beveled side walls places the back walls of the channels in a different plane than the front walls, with the lower edge of the front walls of the channels being positioned in a common plane along with the lower edge of the blade members. The angled side walls impede the formation of a film of water across the inlet opening into the channel, which requires an increase in horsepower for the fan to push air through the drift eliminator. Mechanical fastening devices molded into the respective members connects the corrugated spacer members and the blade members. A method of forming the corrugated spacer members to provide the angled side walls is also provided.

Drift eliminator with formed beveled tip

A method of connecting contact sheets to form a contact body that provides for mechanically deforming at least same of both interior and edge projection-depression couplings formed in two sheets to form positive locks in a pair of sheets, and then mechanically deforming only edge projections to form positive locks between at least two pairs of sheets, thereby forming the contact body.

Method of making contact bodies

An apparatus for connecting contact sheets to form a contact body is disclosed, that provides for deforming projection-depression couplings formed in two or more interlocking sheets to form positive locks by which assemblies of sheets are formed. The apparatus includes crimping devices that crimp projection-depression couplings located in the interior area of the interlocked sheets and projection-depression couplings located adjacent the side edges of the interlocked sheets, again to form positive locks by which assemblies of sheets are formed.
