Abstract
The device comes in the form of a gun with a body, a grip handle and a control component. The body has coaxially a hollow protruding aiming rod equipped, at its free end, with a cylinder containing the threads. The rod is capable, under the action of the control component, of allowing a thread ejection needle to move so that a loop is formed on emergence from the cylinder. The cylinder is mounted at the end of a fixed translation axis and engaged inside the rod; the other end of said axis engaging with a mechanism capable of partially rotating it and the cylinder, when said control component is released, in order to position another thread opposite said ejection needle.
