Abstract

The invention relates to a method and a device for knotting the end of a thread to a flat object containing two spaced holes for the knot. The method provides the thread located in front of the holes is pulled to the other side of the object while forming loops, and in that the loop is rotated by at least 270 DEG . Subsequently the end of the thread is pulled through this loop and the knot that is formed is tightened. The device provides three tools, specifically two bars and a gripper.

Description

technical field

[0001] The present invention relates to a method and a device for knotting a thread end on a flat object, in particular a teabag and / or a label for serving a beverage, having two spaced apart holes for knotting. Background technique

[0002] A number of methods and devices are known for knotting wire ends on flat objects. Most of the needle-operated methods are very complicated and thus limited in their working speed. The associated devices consist of a large number of components whose motion sequences are very complex, so that a relatively high technical outlay is required, especially for the control components.

[0003] Knots produced using known methods and devices are formed between a hole and a side of the flat object. The threads making up the knots are thus distributed in the direction of the fibers of the paper sheet making up the flat object. When the knot is stressed, it can cause the sheet to tear, especially if there is an opening for the threa...
