Title: Innovations by Francois Fischer in Yarn Selection Technology

Introduction

Francois Fischer is a notable inventor based in Carouge, Switzerland. He has made significant contributions to the field of knitting technology, particularly in yarn selection mechanisms. With a total of 2 patents, his work has advanced the efficiency and functionality of knitting machines.

Latest Patents

Fischer's latest patents include a "Method of and apparatus for joining a selected yarn to a yarn being knitted" and a "Device for selecting yarns for a knitting machine." The first patent describes a yarn-selecting device that features a mechanism for joining the yarn being knitted to a selected yarn. This mechanism includes a swiveling finger that forms a closed loop of the yarn to be knitted. Two levers create an open loop of the yarn being knitted, which is then inserted through the closed loop. A hooking lever pulls the yarn to be knitted through the open loop, after which the open loop-forming lever is retracted, cutting the yarn being knitted with a knife while releasing the end of the yarn to be knitted from a gripper.

The second patent outlines a device for selecting yarns, where the yarns are mounted on a selecting rocker that pivots about an axis and is held by a clipper. The yarn is selected by this rocker and raised by a lever. A finger performs two turns to form a closed loop of the selected yarn. An arc-shaped rod, integral with an oscillating arm, brings the yarn being knitted into the open end of the finger. A hook takes the closed loop of yarn while oscillating and returns to its initial position, releasing the loop and gripping the yarn being knitted, which is then cut by the clipper.
