Abstract
The tuck-in needle of a mechanical selvedge-forming device has a catcher for a yarn end following a needle tip. The catcher is subdivided into an entry zone and a trough screened from the entry zone by a hook disposed towards the trough. In its catching movement the needle is moved only towards the weft yarn so that the yarn moves into the entry zone of the catcher. The weft yarn then slides inclinedly over the outside of the hook until passing by way of the hook tip into the catcher interior. The weft yarn can be drawn into the cloth selvedge in this position. This construction enables the tucking-in to be very simple.
