Abstract

The auxiliary warp threads required in a shuttleless weaving machine to form a detachable catch selvage are guided through a special auxiliary reed. In the rest position, the auxiliary reed is positioned tightly against the main reed. The auxiliary reed is so guided in its motion that, in addition to the conventional beat-up motion coupled to the main reed, it also performs an additional displacement directed laterally outwards. As a result, a cutting strip is formed between the fabric and the catch selvage. The projecting filling ends held by the auxiliary warp threads are drawn into the catch selvage during this step. The length of filling yarn required for the cutting strip is drawn from the edge waste projecting over the catch selvage and therefore the waste in filling yarn is reduced by the size of the cutting strip width.
