Abstract: A woven strip of a zipper half is produced of warp and weft threads. The weft thread is picked in the form of double pick loops. A plastic monofilament forms windings of a closing member row on the woven strip with interlocking heads at one end and winding reversing portions at the other end. During weaving, a main knit thread is guided upwardly between the windings to the upper side of the closing member row to form loops with loop heads that are interlocked by crocheting and form a mesh structure for interlocking the closure member row with the woven strip. Simultaneously, double pick loops of the main knit thread are formed and are interlaced during weaving with additional warp threads positioned underneath the closing member row. The main knit thread is used as a weft thread in the woven strip underneath the closing member row.

The shafts of each yoke when rotated are capable of moving the transfer arm between end positions wherein the arm is located entirely to the side of the array and a traversing position wherein the arm extends through the array and is engaged with the two shafts. Thus, by rotating the shafts and operating the latching mechanisms it is possible to pass the transfer arm completely through the array from one end position to the other.
