で、切り込みが確実に行われる。[Operation] According to the present invention, the angle at which the air scissors cut the edge end is not an angle with respect to the running direction of the fabric, but is made in an oblique direction so that the fabric escapes in the running direction with respect to the cut, so that the fabric does not get caught by the air scissors. Moreover, the selvage end is guided by two upper and lower cloth guide plates and fed between the fixed blade and the drive blade, which are opened next to the air scissors to make cuts, so the blades are opened to make continuous cuts. The end of the ear can be guided smoothly between the two. Moreover, since the fixed blade and the driving blade are forcibly secured to mesh with each other during cutting by the backing plate and the pressing force means, the cutting can be performed reliably.
以下、本考案の一実施例を図面を用いて説明す

とを防止するようにしている。 Figure 1 is a plan view of the fabric edge cutting device, Figure 2
The figure shows a front view of the same, and when the running direction of the cloth 1 is a straight line shown by arrow A, the air scissors 2 are tilted backward by a required angle α with respect to the running direction A fabric selvage end cutting device is fixedly installed to make the incision 4 in the direction in which the fabric 1 running in the direction of arrow A escapes from the air scissors 2, rather than in the direction perpendicular to the edge 3a of the edge 3. . That is, by cutting in the diagonal direction, the cloth 1 is prevented from being caught in the meshing portion of the air scissors 2.

れ、ここにエアハサミ2が装備される。 The fabric edge cutting device has upper and lower fabric guide plates 5 and 6. Both cloth guide plates 5 and 6 are arranged in parallel and fastened to the base block 7 with bolts and nuts 8, and the edge end portion of the cloth 1 is inserted between both plates. In addition, a scissor attachment opening 9 is provided at the widthwise central portion of the fabric guide plates 5 and 6 on the side of the base block 7, and the air scissors 2 are installed here.

噛合い不良が生じるためである。 The air scissors 2 have a fixed blade 10 on the upper side and a driving blade 11 on the lower side with the running cloth 1 in between, and both blades are connected at a fulcrum 12 and a holder 13
be equipped with. This holder 13 is fixed to a pedestal 14, and as described above, fixes the air scissors 2 at a constant angle α with respect to the cloth running direction A. Although not shown in the holder 13, a well-known mechanism for continuously driving the drive blade 11 by air pressure supplied through the hose 15 is housed. In addition, fixed blade 1
0 is located on the downstream side of the drive blade 11 in the cloth running direction. In the case of the opposite arrangement, when the driving blade 11 cuts into the cloth 1, the driving blade 11 tends to separate from the fixed blade 10 due to the pressure in the running direction of the cloth 1,
This is because poor meshing occurs.

る。 Generally, when cutting something with scissors, the object is
It must be inside (between) the two blades. When the scissor blades are completely closed, the object is cut and no longer lies between the two blades. If it is the edge 3 of the running cloth, the edge 3 will be on the outside of the scissor blade the next time the blade opens. This is an unavoidable problem unless the time during which the scissors remain closed when making cuts in the running fabric 1 with fixed scissors is made zero. The two cloth guide plates 5 and 6 always sandwich the edge 3 of the cloth 1 and function to continuously guide it inside (between) the fixed blade 10 and the driving blade 11 of the air scissors 2. To enable continuous cutting with air scissors 2.
反物ガイドプレート5,6のハサミ取付け用開
口部9は幅が約10mmとなつている。この間隔が小
さすぎると耳端3が引掛かり、大きすぎると耳端
3をガイドできない。 The scissor attachment openings 9 of the fabric guide plates 5 and 6 have a width of approximately 10 mm. If this interval is too small, the edge 3 will get caught, and if it is too large, the edge 3 cannot be guided.

が必要である。 The distance between the two cloth guide plates 5 and 6 is approximately 5
mm was appropriate. If this interval is too small, the edge 3 will get caught, and if it is too large, stable guidance will not be possible. The outer shape of the plate depends on the installation space and the installation direction (horizontal, vertical), but of course the larger the plate, the more stable the guide will be, and at least the space between the plates will be maintained even when the cloth 1 is stopped and no tension is applied. It needs to be large enough that it won't slip off.
以上のような構成により、走行中の反物1に対
し停止中とほぼ同様に耳端3に切り込み4を入れ
ることができる。 With the above configuration, it is possible to make the cuts 4 in the edges 3 of the moving fabric 1 in almost the same way as when the fabric 1 is stopped.
しかしエアハサミ2の刃が閉じているにもかか
わらず、耳端3は切り込まれない現象が発生する
場合があつた。このため刃が状態等を鋭意検討し
た結果、反物1の走行力がエアハサミ2の刃に加
わり、噛合せに影響を与えたためと判明した。 However, even though the blades of the air scissors 2 were closed, there were cases in which the ear ends 3 were not cut. As a result of careful examination of the condition of the blades, it was determined that the running force of the cloth 1 was applied to the blades of the air scissors 2, affecting the engagement.

しまう。 Generally, the engagement of scissors shifts from the base to the tip as the two blades close due to the warp during cutting. The strength of the engagement is adjusted by tightening the screw at the fulcrum. However, in the case of air scissors, since it is not possible to adjust the degree of engagement based on the sensation of human hands, a spring is attached to the fulcrum portion 12 to bring the fixed blade 10 and the driving blade 11 into close contact with each other. In other words, there is an escape due to the spring corresponding to the warpage of the blade, causing unstable movement (play) when an external force is applied, and the blade does not mesh due to the escape due to the spring, resulting in the edge 3 being caught.
この現象を防ぐため、固定刃10に対しては走
行反物の下流側から当て板16を当てて逃げを防

ート6に固定されている。 In order to prevent this phenomenon, a backing plate 16 is applied to the fixed blade 10 from the downstream side of the running cloth to prevent it from running away, and a resin straightening block 18 with a cam surface 17 is applied to the driving blade 11. ing. still,
The backing plate 16 is fixed to the upper cloth guide plate 5, and the straightening block 18 is fixed to the lower cloth guide plate 6.

安定して促され、切り込みが確実となる。 The surface of the straightening block 18 in contact with the drive blade 11 is a cam surface 17 as shown in FIG. The cam surface 17 is a curved surface that approaches the drive blade 11 from the bottom to the top, as shown in the figure. Therefore, when the driving blade 11 on the lower side with the cloth 1 in between closes, that is, as it moves upward, the outer surface 11a of the driving blade 11 comes into close contact with the cam surface 17, and by this cam surface 17, it is moved in the direction of the arrow. is subjected to a pressing force F. This pressing direction is a direction in which the driving blade 11 comes into close contact with the fixed blade 10,
This is further received by a caul plate 16. As a result, the two blades 10 and 11 are strongly and stably engaged, and cutting is ensured.

げない。 The speed of the running cloth is up to 30m/30m as shown above.
Since it is 150 minutes, the pitch of the cut to the edge of the ear is 150 minutes.
mm, it can cut 200 times per minute. It is known that a highly responsive solenoid valve is used to increase the frequency of operation of air scissors, and that a position detector such as an encoder is used to ensure a predetermined pitch, and this invention cannot prevent such use. .
