Abstract: A warp breakage/end sensing system and device are configured to detect an end of a warp yarn on a circular weaving machine. A mechanism causes a notification signal to be sent to the loom operator in the situation where a yarn breakage is detected. A drop wire loses its elevation and falls from its normal operative position. The drop causes a first element to rotate and come in contact (physical or non-physical) with a second element, thereby completing an electric circuit and sending a yarn breakage signal to the operator. Upon restoration of the yarn, the first element restores to its normal working position. In the case of a non-physical contact, the first sensing element enters the triggering region of the second sensing element thus causing a signal to be sent.

The method of producing the leno weave includes the steps of providing a line segment of the stationary warp thread which connects first and second planes provided on the respective sides of the stationary warp thread, inclining the line segment of the stationary warp thread so as to cross a weaving plane alternately from an upper side of the first plane to an under side of the second plane, and from an under side of the first plane to an upper side of the second plane, and moving the cross warp thread in a perpendicular direction relative to the weaving plane and above the inclined line segment so that the cross warp thread is caused, during its movement, to slide along the inclined line segment towards the first plane or the second, thus producing the leno weave.

Abstract: A loom-controlled leno or cross-weaving system, alone or in conjunction with tabby or ordinary weaving. The leno heddle is composed of two upright members, each connected to two flexible cross-members. Each upright member is connected to a separate, independently moving portion of the loom frame. Each cross-member has an eye in the middle for the passage of the warp thread. The upper cross-member is positioned below the lower cross-member when the warp threads pass through the eyes. Alternation of the elevation of the upright members causes the warp threads to alternate positions laterally. Leno weaving is achieved with a throw of weft for every alternation of upright member position. Tabby weaving is done using a rising loop and a falling loop, each connected to the loom frame independently. One warp thread goes through the eye of the upper cross-member and also through the rising loop. The other warp thread passes through the eye of the lower cross-member and the falling loop.

Abstract: Feathered edges of fiberglass fabrics woven on a shuttleless or airjet loom are secured and prevented from ravelling by a glass yarn coated with a hot melt composition.

A procedure for applying a hot melt to a yarn through a heated die is used.
