Embodiment Construction

[0025] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0026] Figure 1~4 Shown is an embodiment of the present invention. The selvedge device 10 is composed of a side yarn shedding mechanism 20 and a side yarn supply mechanism 30. Such as figure 1 and 2 As shown, the side yarn shedding mechanism 20 is supported by a support block 5 and the like on a cross bar (beam) 3 erected between the side frames 1, 1 on both sides of the loom, and is arranged on a warp composed of multiple warps. Near column T. In addition, the side yarn supply mechanism 30 is supported on the side frames 1, 1 on both sides of the loom via the support block 7 and the like.

[0027] Such as Figure 1~3 As shown, the side yarn shedding mechanism 20 of this embodiment has a dedicated drive motor 24 as a drive source, and an arm 26 as a rotating body mounted on the output shaft 24a of the drive motor 24. In addition, the support block 5 on the cross...

Abstract

A selvage device in a loom has a rotary member provided with guides for guiding selvage yarns, and rotates the rotary member to move the selvage yarns in a shedding motion. The selvage device includes a selvage shedding mechanism having the rotary member and a designated driving motor that rotates the rotary member unidirectionally in an intermittent fashion; and a selvage feeding mechanism disposed upstream of the selvage shedding mechanism in a traveling direction of the selvage yarns. The selvage feeding mechanism includes a guide unit having a pair of guide portions for guiding the selvage yarns respectively fed from a pair of yarn feeders; and a rotating unit supporting the guide unit and rotated continuously in the same rotational direction as the rotary member. The guide portions revolve in response to the rotation of the rotating unit, such that sections of the selvage yarns extending from the yarn feeders to the corresponding guide portions revolve without intercrossing each other.

Description

Technical field [0001] The present invention relates to a selvedge device of a loom, in particular to a loom selvedge device in the form of rotating a rotating body forming a pair of guide portions for guiding the side yarn and performing a shedding movement on the side yarn. Background technique [0002] As the selvedge device of the loom of the above-mentioned form, it is described in Patent Documents 1 and 2. In the selvedge device described in Patent Document 1, a pair of arms are formed with eyelets that respectively pass through and guide the side yarns (binding yarns), and the arms are driven to rotate by a dedicated drive motor. The side yarn is twisted while opening movement. [0003] In the selvedge device of the above-mentioned form, by the rotation of the arm, twisting between the side yarns occurs on the upstream side (side yarn supply side) (the state where the two side yarns are entangled with each other). The twisting between the upstream side yarns increases in p...
