Abstract
The improved latch needle ( ) is provided with a latch ( ) having a latch shaft ( ) with side surfaces ( ), which are divided into surface areas ( ) that are offset against each other and/or are arranged at an angle to each other. As a result, the thickness of latch ( ) measured in the direction of its rotational axis ( ) is slightly larger than the thickness in the shaft region ( ), particularly at a location ( ) in the area of transition from the latch shaft ( ) to the latch spoon ( ). On the other hand, the location ( ) is close to the hook-side opening of the latch slot ( ). By reducing the width, particularly in this region, the easy movement of latch ( ) is ensured even if dust or dirt enter the latch slot ( ) or are deposited on the side surfaces ( ).
