This stitch is composed of a single string/thread and is common on dogfood and grain sacks. It can be removed by just pulling on the end. Here is an example I found on youtube.

  • More important: how come this release mechanism fails to work on 2 out of three bags :-(

It is called "chain stitch" and was the stitch used in the first designs of sewing machines, because it is easy to produce mechanically. The fact that it can be pulled out unless the end of the string is knotted (as explained in the OP's video link) is a disadvantage for most purposes. For example, if the string breaks one side of the break will often quickly unravel.



The standard sewing machine stitch is now "lock stitch" which uses two threads, not one, and can't be pulled undone in the same way. Chain stitch is only used for special applications, or as decoration.



See https://home.howstuffworks.com/sewing-machine1.htm for an animation of how both stitches are made by machine.

Section du cône ou projection du cercle. En géométrie, une ellipse est une courbe plane fermée obtenue par l’intersection d’un cône de révolution avec un plan, à condition que celui-ci coupe l'axe de rotation du cône ou du cylindre : c'est une conique d'excentricité strictement comprise entre 0 et 1. On peut également la définir comme le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante (sa construction par la méthode du jardinier est très simple). Dans la vie courante, l’ellipse est la forme qu'on perçoit en regardant un cercle en perspective, ou la figure formée par l’ombre d'un disque sur une surface plane. On retrouve aussi, en première approximation [ 1 ] , des ellipses dans les trajectoires des corps célestes (planètes, comètes ou satellites arti
