ABSTRACT:
In a method and an apparatus for producing a woven web (1) having a permanent fabric list (2) and a temporary catch selvage (3) along edges of the woven web (1), the weft thread is inserted into a main loom shed, fabric list shed, and catch selvage shed, and is then beat-up and bound-in in each shed. Both the fabric list (2) and the catch selvage (3) are formed as full rotation leno bindings, respectively by means of a first rotational leno device (12) having a first leno rotor (12A) guiding and manipulating fabric list threads (7) and a second rotational leno device (13) having a second leno rotor (13A) guiding and manipulating catch selvage threads (9). Each leno device (12, 13) may operate with or without reversal of the rotation direction. The two leno devices may be independently driven by separate rotary drives, or may be mutually driven by a common drive. The leno devices may be operated to bind-in the weft threads with the same or different binding patterns, relative to each other and relative to the main shed of warp threads. In this manner, a compact arrangement is achieved, the amount of thread needed for the catch selvage strip and for weft threads is reduced, the full advantages of the rotational leno devices can be obtained, and the loom can operate at its full speed.
