Description

[Detailed description of the invention] The present invention consists of a shuttle main body having a slider insertion hole connected to one end of a sliding groove into which a slider can fit, and a shuttle body that is detachably attached to the slider insertion hole. By providing a sliding groove garment and a fixing member for fixing the garment, the weft thread being let out can be cut or damaged if it gets caught between the groove bottom of the sliding groove and the slider. The present invention relates to a shirttle that not only can reliably avoid such risks but also can easily, quickly, and reliably attach and detach clothing to and from a slider insertion hole.

A shirttle that adjusts the weft tension using a slider has a slider insertion hole connected to one end of the slider groove for inserting and removing the slider, and also inserts the slider into the slider insertion hole. It is configured to attach a slider stopper to stop the slider.

As shown in FIGS. 3a and 3b, the conventional slider stopper a was formed as a U-shaped body made of synthetic resin with side plates C and c erected on both sides of the bottom plate.

The length of the bottom plate is such that the slider insertion hole g is such that both end portions d, d', and d' can be engaged with the sliding groove e and the locking groove f facing the sliding groove e. The side plates C, c are formed to be slightly longer than the length of the thread guiding hole i of the slider.
In order to make it easier to thread the weft through the weft, the slider can be moved and stopped.
In order to facilitate the installation of the slider stopper a into the slider insertion hole g, the front ends j and j of the slider stopper a are
It was provided so that it was located slightly away from the end k of the.

However, in order to attach the slider stopper a to the slider insertion hole g, first, one end portion d of the bottom plate is engaged with the sliding groove e, and then,
Since the other end portions d', d' of the bottom plate must be forcibly engaged with the locking grooves f, f, the installation is not only extremely difficult, but also requires the slider stopper a. could easily cause damage.

Also, as mentioned above, since the front ends jwJ of the side plates C and c are located away from the end k of the sliding groove e, when the slider stopper a is installed in the slider insertion hole g, the slider When the receiver is stopped and stopped by the front ends J9j of the side plates c and c, a portion of the slider comes off from the sliding groove e, as shown in FIG.

In such a shuttlecock, when the detached slider returns to the sliding groove e, the weft pulled out from the thread guide hole i of the slider sometimes becomes unstable and sagging due to impact during picking. From the end k of the sliding groove e to the sliding groove e
This can cause accidents such as getting stuck in the groove and getting caught between the groove bottom 1 of the sliding groove e and the sliding groove, resulting in cutting or damage, which not only degrades the quality of the woven fabric but also reduces weaving efficiency. There were various problems.

The slider stopper a, which has been improved so that it can be easily installed in the slider insertion hole g, has a bottom plate m shorter than the length of the slider insertion hole g, as shown in FIGS. 4a and b. and two elastic side plates 11. n to form a U-shape, and in order to be able to shift and stop the slider as described above, both side plates n and n are formed in a stepped shape, and a slider stopper is also provided. As a means for fixing a to the slider insertion hole g, it is removably fitted into locking holes 0, 0 provided on the upper and lower inner walls of the slider insertion hole g on the outside of both side plates n, n. A locking protrusion pt p has also been proposed (see Japanese Utility Model Publication No. 55-55273).

The slider stopper a utilizes the elasticity of the side plates n, n to fit the locking protrusions p, p into the locking holes o, o, or to lock with the locking protrusion pt1). Although the slider stopper a shown in FIG. Similarly, the side plate n with a stepped sliding slider
, n, when the receiver is stopped and stopped at the front ends q, q, a part of the sliding shear comes off from the sliding groove e (indicated by symbol r), and as a result, the weft yarn is moved into the sliding groove e. There is still a risk that the groove bottom 1 of the groove 1 and the slider may be caught between them and be cut or damaged.

In view of such conventional problems that occur in the slider insertion hole, the present invention reliably prevents the possibility that the weft thread to be let out will be caught between the bottom of the slider groove and the slider and be cut or damaged. The purpose of this invention is to provide a shirt handle that not only avoids the above problems but also allows the fitting of the sliding groove to be attached and detached from the slider insertion hole extremely easily and reliably, and one embodiment thereof will be described below based on the drawings. do.
