Title: **Robert Lehmann: Innovator in Yarn Production**

Introduction

Robert Lehmann, an accomplished inventor based in L'Arbresle, France, has made significant contributions to the textile industry with his innovative approaches to yarn production. With a total of two patents to his name, Lehmann's work focuses on creating fancy yarns that enhance both functionality and aesthetic appeal.

Latest Patents

Lehmann's latest patents revolve around the processes and devices for producing fancy yarn. The first patent describes a method for producing fancy yarn with protuberances along its length, utilizing a multi-filament yarn that is forwarded by a positive drive means. This method simplifies production by eliminating the need for a binding or effect yarn. The yarn is twisted and taken up by a spindle, engaging with the surface of the drive means, where the edge brakes some of the filaments.

The second patent details a method of making fancy yarns, where at least two yarns are employed—one serving as a core and the other as an effect yarn. These yarns are fed to a junction point and pass through a heat treatment zone, where they are assembled into the final fancy yarn through a false twisting step. The core yarn is treated with a thermoplastic binder that adheres the effect yarn to it, presenting a novel way to create decorative textured yarns.
