Title: Markus Widrig and His Patent for Producing Sheet Metal Laminates

Introduction

Markus Widrig is an inventor associated with Wangen, Switzerland. His patent concerns a method and device for producing bundles of sheet metal laminates used in magnetic cores.

Latest Patents

Widrig’s listed patent, “Method and Device for Producing Bundles of Sheet Metal Laminates for Magnetic Cores,” describes a punch-packeting process for making sheet metal packets with round or oval iron cross sections. The method punches laminations from a metal strip, forming depressions on one side and matching raised features on the other. At least two circular nipples are pressed into corresponding depressions to join the laminations.

A separating lamination uses cylindrical holes instead of depressions, allowing the neighboring lamination’s nipples to engage with it. The process also uses laminations with different outside contours, including different widths, to create packets with graduated edges and at least partially round cross sections. Widrig is credited with 1 patent.

Career Highlights

The available information identifies Widrig’s work through this patent and its manufacturing approach. The invention focuses on joining punched laminations into magnetic-core packets while accommodating variations in their contours.
