  The present invention is to make it possible to efficiently obtain a four-fold overlap fabric in the above-mentioned overlap fabric in a relatively short distance range in which the fabric fabric is drawn out of the winding beam and travels. Thus, it is an epoch-making product that can be produced at low cost with a new method and a device with a simple configuration that have not been proposed in the past.

  The method of the present invention includes a base plate formed so that the width of the upper base that becomes the upper end when positioned in an upwardly inclined position matches the double folding width of the raw fabric, and the upper base portion of the base plate The center of the folded folding width is the apex, and the upper leg width dimension is formed in the middle of the leg opening, the isosceles triangular holding plate, and a pair of overlapping rolls. While the fabric is running on the base plate, the both ends of the fabric are pulled into the back side from the middle of the base plate and pulled to the upper base width interval, and the middle leg of the upper base crosses at the left and right end edges. The V-shaped legs are arranged in a horizontal state so that the apexes thereof coincide with the running direction of the fabric and the center line of the width interval of the fabric, and the both ends of the ears coincide with each other at the apex portion of the V-legs. To form a double fold and then run the double fold fabric The embedding plate is positioned so that the width direction and the base of the isosceles triangle are perpendicular to each other and the base is opposed to the upper base, and the apex of the isosceles triangle is in the descending direction. The direction of travel of the double-folded fabric that has traveled horizontally between the base and the base is changed to the travel direction on the holding plate at the base, and the folding is performed so as to hold the symmetrical side plate of the isosceles triangle shape. It is characterized in that it is formed into a quadruple fold by converging both side ends of the layered fabric toward the center of the width interval in the running direction and passing between the pair of overlapping rolls so as to sandwich this. Further, in order to carry out the above method, the apparatus of the present invention is configured such that the base plate disposed in an upward slope, the isosceles triangular holding plate disposed so that the symmetrical side plate is in the descending direction, and the base plate In the horizontal direction of the upper base, both side ends thereof are arranged so as to cross the upper base in the middle of the opening leg, and the apex is between the base plate and the bottom of the holding plate and The above-mentioned V-shaped leg arranged on the center line of the width interval and the cloth which is arranged at the lower center of the holding plate and is converged with the both ends of the folded cloth toward the center of the width interval in the running direction are sandwiched as they are And having the pair of overlapping rolls to be guided.

In the present invention, since the bottom of the holding plate is arranged at a position facing the upper base, the state in which both ears are matched at the apex of the V-shaped leg is held in a double folded state. It reaches the bottom of the included board. Thereafter, since the angle of the holding plate is in the descending direction, the cloth folded twice is pressed against the bottom side of the holding plate, and the state of the double folded cloth is fixed. In addition, between the bottom of the upper base holding plate, the V-shaped legs provided in a horizontal state are in a state where the middle part of the leg crosses at the left and right edge portions of the upper base, The double-folded cloth travels horizontally to the bottom of the embrace plate. Accordingly, the cloth fed from the upper base only slides on the V-shaped leg until the cloth reaches the bottom of the embrace plate, and both ear ends coincide with each other at the apex portion of the V-leg. To the bottom. For this reason, since the restriction | limiting of the width direction with respect to cloth becomes only the part of the upper base which is a starting point of a horizontal state, it can reach to the bottom side of a holding-in board as the state which matched the both ears of cloth correctly. In addition, as the device, the base plate is arranged in an upward inclination, arranged in the descending direction with the holding plate, and the pair of overlapping rolls are arranged in the lower center of the holding plate, so that the entire space is relatively small. It can be done in the space.

FIG. 1 is a perspective view schematically showing the configuration of the present invention, FIG. 2 is a side view, and FIG. 3 is an explanatory view showing the running state of the fabric as viewed from the bottom side.
In each figure, 1 is an original fabric to be folded in four, 2, 3 and 4 are technical means necessary for the four-fold process, and 2 is the width dimension s of the upper base 2a. This is a base plate made to be 1/2 of the width dimension L of the fabric 1.

  Reference numeral 3 denotes a V-shaped leg having a width dimension s of the upper base 2a between the open legs, which is disposed in the horizontal direction on the upper base 2a. In addition, the V-shaped head 3a is in the running direction of the fabric 1 and coincides with the center line of the width interval of the fabric 1, and the V-shaped leg on the left and right edge portions m and n of the upper base 2a. The three legs 3a and 3b are arranged so as to intersect with each other.

  In the present invention, the both-side ear ends e and f of the fabric 1 traveling on the base plate 2 with the above-mentioned configuration travels from the middle of the base plate 2 to the back side thereof as shown in the example of illustration, and the upper base 2a. The left and right edge portions m and n of the V-shaped leg 3 are regulated by the open legs 3b and 3c of the V-shaped leg 3 so that the width interval becomes 1 / 2L. As can be seen from FIG. 3, in the process of reaching the head 3a of the V-shaped leg 3, both ears e and f of the fabric 1 are drawn to the center and matched at the head 3a. At this point, the fabric 1 is formed with the first fold.

  4 is an isosceles triangular holding plate, which is positioned in a direction perpendicular to the width direction of the fabric 1 traveling in front of the V-shaped leg 3 to change the traveling direction of the fabric 1 and In this example, the plate 4 is arranged in a downwardly inclined manner, the direction of the traveling fabric 1 is changed downward, and the isosceles side of the plate is formed. The two ear-folded ends of the fabric 1 folded in half are moved through the triangular symmetrical side plates v and w so as to embrace (b) them, and the isosceles triangular folding plate 4 They are overlapped so as to coincide with each other at the lower center, and a four-fold is formed at the location together with the original two-fold.

  Reference numeral 5 denotes a pair of overlapping rolls provided at the above-described locations, and the above-described four folds are sandwiched as they are and guided to the take-up roll. Reference numeral 6 denotes a winding roll for winding the above-described four-fold fabric. Here, although what showed winding up four-fold cloth with a winding roll was shown, it was made to use a cutting machine in the running process, without winding up, and cut it into a suitable length size, and to make it a product. Also good.

  The method of the present invention is carried out as described above. This is an apparatus in which the base plate 2, the V-shaped leg 3, the holding plate 4, the overlapping roll 5 and the like of the above-described example are arranged in this order on a standing rectangular frame. Specifically, the base plate 2 is inclined upward by about 50 ° toward the front side of the above-described rectangular frame, and the V-shaped leg 3 is horizontally held on the ceiling surface and is held. The insert plate 4 is attached to the rear surface side of the rectangular frame in a downward inclined state of about 60 °, and includes the support bearing of the raw fabric 1 and the support bearing such as a superposition roll. It may be configured to be attached. It is also possible to cover them and arrange them separately from the rectangular frame.

  The base plate 2 described above uses a standing support of a square frame, that is, it can be substituted with a structure in which a plurality of piers are installed via appropriate brackets, etc. The embedded plate 4 is not limited to a plate body, and may be configured using a bar material, and these are included within the scope of the present invention.

  The above-described configuration of the present invention is compact and can be disposed even in a relatively narrow place, and not only contributes to space saving and cost reduction, but also dramatically improves productivity.

It is a perspective view which shows the structure of this invention typically. It is said side view. It is explanatory drawing which shows the running state of a fabric looking up from said bottom face side.
