摘要： A weft detaining device of a shuttleless loom, comprises a drum on which a weft yarn is wound predetermined times prior to a weft picking through a weft picking means, the drum being constituted by a plurality of separate and independent pieces, a support member on which the drum separate pieces are securely supportable, and a device for allowing the location of each drum separate piece to be movable relative to the support member so that the outer diameter of the drum is adjustable, thereby making possible changing a weft picking length by merely changing the location of each drum separate piece, without replacing the drum with the other drum having a different diameter or using any members to be mounted on the peripheral surface of the drum to adjust the outer diameter of the drum.

摘要： A tack-in system of an air jet loom, for forming a tack selvage at an edge section of a fabric. The tack-in system is comprised of a body of a tack-in device, which body is formed with a slit. The slit is located near an edge of an array of warp yarns. A weft yarn picked from a weft picking nozzle extends through the slit. The end section of the weft yarn picked and cut by a cutter is securely held in such a manner that at least a part thereof is located within the slit. A fluid jet nozzle is provided to eject a fluid jet from its opening which is located such that the fluid jet therefrom blows the weft yarn end section. The fluid jet from the fluid jet nozzle is so directed that the axis thereof crosses the cloth fell at an acute angle, thus securely pressing the weft yarn end section onto the cloth fell.

摘要： A tack-in selvage forming apparatus for tacking in the end portion of a picked weft yarn to form a selvage structure in weaving a towel. The tack-in selvage forming apapratus is comprised of a tack-in needle which is controllably driven by a driving mechanism including a cylindrical grooved cam rotatable in timed relation to a main shaft of a loom. The grooved cam is formed at its periphery with generally annular shallow and deep cam grooves. The shallow cam groove is parallel with a plane perpendicular to the axis of the grooved cam, while the deep cam groove is curved relative to the same plane. A part of the shallow cam groove and a part of the deep cam groove is common and the same in depth. The shallow cam groove has a profile corresponding to a resting state of the tack-in needle, while the deep cam groove has a profile corresponding to a tack-in operational state of the tack-in needle. A cam follower drivingly connected to the tack-in needle is selectively put into the shallow and deep cam grooves. Thus, the tack-in needle is rested when the cam follower is in the shallow cam groove and operated to accomplish tack-in of a weft yarn end portion when the cam follower is in the deep cam groove.
摘要翻译：用于在拾取的纬纱的端部粘合以形成编织毛巾的缝合结构的粘合式成形设备。粘合缝合成形衬垫由一个固定针组成，该针由可驱动的驱动机构驱动，该驱动机构包括可以与织机的主轴定时关联的圆柱形凹槽凸轮。凹槽凸轮在其周边形成有大致环形的浅和深凸轮槽。浅凸轮槽与垂直于凹槽凸轮的轴线的平面平行，而深凸轮槽相对于同一平面弯曲。浅凸轮槽的一部分和深凸轮槽的一部分是相同的并且深度相同。浅凸轮槽具有对应于上述固定针的静止状态的轮廓，而深凸轮槽具有对应于上述固定针的固定操作状态的轮廓。驱动地连接到拾取针的凸轮从动件选择性地放入浅和深凸轮槽中。因此，当凸轮从动件处于浅凸轮槽中时，固定针停止，并且当凸轮从动件位于深凸轮槽中时，操作以实现纬纱端部的固定。

摘要： The row of air guide members comprises a nozzle-mounted air guide member having around the air guide opening a plurality of air ejection holes, a first group of air guide members located downstream of the nozzle-mounted member and positioned between the nozzle-mounted member and the point at or about which the inboard boundary of the auxiliary air flow from each air ejection hole intersects the axis of the air guide channel of the row of the air guide members, and a second group of air guide members located downstream of the first group of air guide members. The air guide openings of the first group guide members are larger than the air guide opening of the nozzle-mounted member and gradually reduced in diameter with increase of distance from the nozzle-mounted member. The air guide openings of the second group members are identical to each other and to the air guide opening of the nozzle-mounted air guide member.
