It is possible to freely reciprocate between the side of the cloth mounting table 26 and the upper side of the cloth mounting table 26. The reciprocating movement is performed by, for example, an air cylinder (not shown) attached to the moving member 15. Reciprocating motion by electric motor is also possible. Reference numeral 16 denotes a clamping tool attached to the moving member 15, for example, a device called an air chuck is used. 17, 1
Reference numeral 7 denotes a pair of opening/closing members in the clamping tool 16, which move in parallel to each other (opening/closing operation). The stroke is, for example, about 4 to 5 mm in total, and the chucking force is, for example, about 1.5 kgf. A pair of clamping pieces 18, 18 are attached to the opening/closing members 17, 17, and are made of a flexible and elastic material. For example, it is made of a stainless steel plate with a thickness of about 0.6 mm. Reference numerals 20 and 20 indicate the clamping portions of the clamping pieces 18, 18, and the tip portion 20b is smaller than the distance G1 between the base portions 20a.
The mutual spacing G2 between the two is narrowed. The distance G1 is determined by the closing operation of the pair of opening/closing members 17, 17.

Reference numeral 21 denotes an attaching portion of the clamping piece 18 to the opening/closing member 17; 22 denotes a bringing-out portion;
A portion 23 for increasing flexibility is a bent portion for setting an interval, which is bent in order to set the above-mentioned interval G1 to a desired size with respect to the interval between the mounting portions 21. Note that the clamping tool 16 has a pair of opening/closing members 17 that perform opening/closing operations relative to each other.
17, other actuating means other than air may be used, such as one using electromagnetic force.

Next, prior to explaining the supply of U-shaped labels by the label supply device, the hem forming device 25 shown in FIG. 2 will be explained as an example of a device that receives the supply. The device 25 includes a cloth placing table 26, a primary and a secondary
The following bending tools 27, 28, a ruler 29, etc. are provided. A cloth (for example, a towel) 3 placed on the table 26
0 by the movement shown by the arrow 31 of the primary folding tool 27 as shown in (C), and then the secondary folding tool 2
The fabric is folded twice as shown in (D) by the movement shown by the arrow 32 of 8, and then the second folded portion is sewn at the position shown by the reference numeral 33 to form a hem. For example, it is similar to that shown in Japanese Patent Publication No. 59-46194.

Next, the supply of U-shaped labels will be explained. In FIG. 1, the strip 4 is cut by the cutting device 1, and one label 35 is sent onto the table 7. Next, as shown in FIG. 2A, with the movable member 15 located at the label clamping location T and the pair of clamping pieces 18, 18 open, the pushing piece 9 moves forward and removes the label from the middle part. Insert into the gap in the receiving member 8. As a result, the middle portion of the single label is folded back to form a U-shaped label 36. 37 is the U-shaped label 3
The folded portion at 6 is shown. As the extrusion piece 9 moves forward as described above, the U-shaped label 36 has a pair of clamping pieces 18, 18 and a clamping part 20 of the pair of clamping pieces 18,
It will be inserted between 20 and 20.

Next, the opening/closing members 17, 17 of the clamping tool 16 are closed, so that the clamping parts 20, 20 clamp the U-shaped label 36 therebetween, and then the push-out piece 9 is retracted, as shown in FIG. The situation will be as shown in B). In this case, the clamping parts 20, 20 have the spacing between the base parts 20a, 20a and the tip parts 20b, 20b set as described above, and have elasticity, so that the clamping parts 20, 20 have elasticity. , 20
The U-shaped label 36 between them is tightly pinched with substantially uniform pressure over its entire area. For this reason, U-shaped label 3
6 is sandwiched between the sandwiching parts 20 over an extremely wide area,
As a result, the U-shaped label 36 has an extremely high resistance to displacement in the plane direction with respect to the clamping portion 20. Furthermore, a folded portion 37 is formed on the inner surface of the clamping portions 20, 20.
The part that comes into contact with becomes a pressing part against the folded part 37,
Press the folded portion 37 from both sides to form a crease exactly there.

The position of the folded part 37 between the clamping parts 20, 20 varies depending on the insertion depth of the U-shaped label 36 by the extrusion piece 9, but the position of the folded part 37 between the clamping parts 20, 20 differs depending on the insertion depth of the U-shaped label 36 by the extrusion piece 9. Since the folded portion 37 can be pressed at any location on its inner surface, the portion in contact with the folded portion 37 functions as a pressing portion even if the location of the folded portion 37 is different. However, if the position of the folded part is always set at a constant position, the inner surface of the clamping part 20 may be provided with a bulging pressing part only at a location corresponding to the position of the folded part. .

Next, the moving member 15 is moved laterally in the direction of arrow 41 and reaches the label supply location S as shown in FIG. 2(C). Due to this movement, the clamping pieces 18,
The free end 38 located on the outside of the cloth 30 comes into contact with the cloth 30 and is bent in the opposite direction to the moving direction of the moving member 15. In this state, the free end 38
It overlaps the next folded edge 30a.

Next, as shown in FIG. 2(D), the edge portion 30a is folded twice, and the free end portion 38 is sandwiched between the edges. After such a situation occurs, the clamping tool 1
The opening/closing members 17, 17 of 6 are separated and the clamping pieces 18, 1
8 will be held. In this case, since the folded part 37 has already been creased, the clamping part 2 of the U-shaped label 36
The portion 39 between 0 and 20 will not swell. Next, the moving member 15 is retracted in the direction of the arrow 42, and the U-shaped label 36 is relatively removed from between the clamping pieces 18, 18. After that, the moving member 15 is moved in the opposite direction to the arrow 41 and further moved in the opposite direction to the arrow 42 to return to the label clamping place T, and the clamping pieces 18 are again moved to the position (A) in FIG.
). In addition, in the heme forming device 25, 2
Next, the folded part is sewn. The above operations are repeated, and the cloth 3 is prepared one after another on the table 26.
U-shaped labels 36 are supplied one after another toward 0.

Next, FIG. 3 shows a different embodiment of the present invention, in which the method of opening a pair of clamping pieces and the structure of each clamping piece are different. In (A), clamping tool 1
One of the pair of opening/closing members 6e (indicated by reference numeral 45) is fixed, and only the other (indicated by reference numeral 46) is movable. One of the pair of clamping pieces 18e, 18e is formed to be relatively thick so that it is difficult to bend and is attached to the fixed side member 45, and the other is formed to be able to bend and move as in the previous embodiment. It is attached to the side member 46. In this example as well, the folded part 37e of the U-shaped label 36e can be tightly sandwiched and pressed between the inner surfaces of the clamping parts 20e and 20e as shown in (B) (the part that contacts the folded part 37e becomes the pressing part). can form creases. It should be noted that parts that are functionally the same or equivalent to those in the previous figure are given the same reference numerals as in the previous figure with the letter e, and redundant explanations are omitted. (Furthermore, in the following figures, the same concept is used and the letters f, g, etc. are added in order, and redundant explanations are omitted.)

Next, FIG. 4 shows an example of a different shape of the clamping piece 18f, in which the clamping part 20f is slightly curved inward as shown in FIG. 4(A). In this example also (
As shown in B), the folded portion 37 is formed on the inner surface of the clamping portions 20f, 20f.
A crease can be formed there by pressing f (the part that contacts the folded part becomes the pressing part).

Next, FIG. 5 shows an example in which a heater 48 for heating the label is attached to the clamping portion 20g of the clamping piece 18g. If such a heater 48 is provided, when the U-shaped label is held and the folded part is pressed by the pressing part, the folded part can be heated and ironed to create an extremely firm crease. In addition, 49 is a connection terminal, 5
0 is the power cord.

Next, FIG. 6 shows an example in which the shape of the holding piece 18h is bent at a right angle at the middle portion. Such a clamping piece 18h is used when another member is located in the space above the clamping piece and the space cannot be utilized. When such a clamping piece 18h is used, the clamping tool 16h is arranged horizontally (a state in which the orientation is 90° different from the example in FIG. 1). The retraction direction 42h when the U-shaped label is released is the horizontal direction. In this example, the distance between the clamping parts 20h, 20h is the narrowest at the point 51 (for example, 2 mm), and the widest at the point 52 (for example, 2 mm).
For example, 5 mm), and the locations indicated by numerals 53 and 54 are located between them. By doing this, when the U-shaped label is clamped between the clamping parts 20h, the folded part of the U-shaped label can be pressed by the inner surface (the part that contacts the folded part becomes the pressing part), A crease can be formed there. The dimensions L1 and L2 are, for example, 47 mm and 40 mm, respectively. These and the above values are determined as appropriate depending on the application.

Next, FIG. 7 shows another example of the shape of the clamping piece 18i used in the same case as FIG. 6.

Next, FIG. 8 shows another example of the clamping tool 16j for opening and closing the clamping piece 18j. 56 is attached to the moving member at a base. 57, 57 are a pair of opening/closing members, which are pivotally connected to the base by a pin 58;
A clamping piece 18j is attached to one end, and the other end is a cam driven portion, to which a friction reducing roller 59 is attached. Reference numeral 60 denotes a cam, which is moved forward and backward in the direction of the arrow by an actuating means (not shown), such as a cylinder. 6
Reference numeral 1 designates an opening spring, which is a push spring and is interposed between a spring receiver 62 provided on the base 56 and the opening/closing member 57.

In such a structure, the cam 6
0 moves back and forth, the pair of opening/closing members 57 respectively swing around the pins 58, and the pair of clamping pieces 18j, 18j are opened and closed. When the clamping piece 18j is closed, the clamping portion 20j
As shown in the figure, the folded part 37j is pressed with its inner surface (the part that contacts the folded part 37j becomes the pressed part), and a crease can be formed there.

[0022]

As described above, in the present invention, when the label 36 is supplied, the label 36 bent in a U-shape is
By inserting the folded part 37 between the pair of clamping pieces 18, 18 at the label clamping location T, the label 36
Of course, by holding the label between the holding pieces 18, 18 and moving it to the label supply location S, the free end 38 of the label 36 protruding from the holding piece 18 can be positioned at a predetermined position.

[0023] When supplying the label 36 as described above,
The folded portion 37 is formed by the pressing portion on the inner surface of the clamping pieces 18, 18.
It has the advantage of being able to supply labels 36 with creases attached to them. This means that at the location where the label was supplied, the label 36
Even if the pair of clamping pieces 18, 18 are opened to release the label 36, it has the effect of preventing the overlapped parts of the label 36 from shifting from each other. As long as the labels 18 and 18 are opened slightly, the label 36 can be easily removed from between them, so the clamping pieces 18 and 18 can be retracted without fear of disturbing the positioning of the tip end 38 of the label 36. There is.
