Abstract: A method and an apparatus for manufacturing a woven slide fastener stringer wherein synthetic resin fastener elements in the form of a continuous spiral are formed at the same time that the fastener tape is woven. In the method, the monofilament for forming the fastener elements is advanced toward a hook on one side of warp bunches from the other side thereof, engaged on the hook at the advanced position and guide into a fell via the one side of the warp and is thereafter deformed into a loop shaped fastener element. The apparatus includes a carrier for advancing the monofilament across the warp bunches and a swinging arm swingably positioned at one side of the warp bunches. The swinging arm includes the hook for engaging the monofilament for forming fastener elements and is swingable between a first position wherein the hook is situated at one side of a fell and a second position wherein the hook is remote from the fell.

Abstract: Disclosed is a woven slide fastener including a row of fastener elements composed of a flat coil formed of a continuous monofilament, and a slide fastener tape having the row of fastener elements woven into a longitudinal side edge thereof. Each fastener element includes a coupling head and upper and lower leg portions joined thereto. Binding warp threads extend along the upper and lower sides of the fastener element row and are woven into the tape along with other warp threads and a weft thread to form a portion where the tape and fastener element row are mutually interwoven, thereby maintaining the perpendicularity of the leg portions with respect to the tape, the stability of the spacing between mutually adjacent ones of the fastener elements, and the smoothness with which the row of fastener elements is coupled with an opposing row of fastener elements.

Abstract: Apparatus for opening and closing a flexible screen in a greenhouse or the like includes a winding rod mounted for rotation about a fixed axis and to which an end edge of an elongated flexible screen is fixed, first driving apparatus for constantly applying a torque to the winding rod tending to rotate the same such that the flexible screen would be wound thereon, and traction apparatus including elongated flexible members, each of which has its two ends secured to a rotatably mounted driving shaft with respective end portions thereof oppositely coiled on the driving shaft and having two portions guided along a predetermined path of travel with one of the portions being operatively connected to the other end edge of the flexible screen, and second driving apparatus for selectively rotating the driving shaft in a normal or reverse direction.
