Abstract

1. Method for manufacturing of the plates of a plate heat exchanger designed of plates (1) stacked upon one another and being provided with embossed projections (2a, 2b) which protrude out of the plane of the plate towards one side or the other side and are located on the lines of a lattice (10), whereby the plates are supported against one another via their projections and whereby the projections define parallel flow channels between adjacent plates, characterized in that the projections are embossed in the plate by at least two consecutive embossing steps by the same tool, with the plate being moved between each two embossing steps relative to the tool by an intergral multiple n of a pitch (T) of the pattern of the projections recurring in the feed direction, that the tool (20) has an active length in the feed direction of the plate which length is equals to said integral multiple n of the pitch (T) of the pattern of the projections plus the length of the pitch (t) of an adjacent projection, that the embossing punches on the first and the last embossing punch line (21, 24) of the tool, which lines extend perpendicular to the feed direction, are mutually displaced perpendicular to the feed direction, and that the number and the position of the embossing punches on the first and the last embossing punch line (21, 24) of the tool (20) are arranged such that the embossing punches of these two lines together form a fully occupied line (for example 16) of embossing punches.
