When the front end of the cloth C hangs down from the conveying end 11 by a predetermined length, one quarter of the total length of the cloth C is scooped from the front end and is provided for vertical folding provided near the conveying end. Between the pair of upper and lower short belts 12 and 13, there is a folding guide plate 14 for pushing in a half of the total length of the cloth C so that the specific portion becomes the lowermost surface and folding it in the longitudinal direction. A vertical folding mechanism A is provided on the front end side of the apparatus main body 10, and is vertically folded at the rear end of the lower belt 12 of the pair of upper and lower short belts 12 at substantially the same height. A vertically folded piece of cloth that carries the central part of the surface that has the specific part of the cloth A conveyor belt 1 having a narrower width is provided, a presser plate 2 for pressing cloth against the conveyor belt 1 is attached to the upper side of the belt 1, and guide plates 3 and 4 for lifting both ends of the cloth above the belt height are conveyor belts. A folding plate 5, which is installed on the left and right along 1 and goes in and out of the pressing plate 2 between the conveyor belt 1 and the guide plates 3 and 4, and folds vertically folded cloth into three in the width direction,
6 is rotatably provided to the left and right of the conveyor belt 1, and a horizontal folding mechanism B, which folds while keeping the specific portion on the lowermost surface, is installed in the main body 10 behind the vertical folding mechanism A. .

(Example) An example will be described. The apparatus shown in FIG. 1 and FIG. 2 is provided with a vertical folding mechanism A for folding the cloth C into a quarter of the length on one side of the main body 10, and the cloth C folded in four is wide. The other side is provided with a horizontal folding mechanism B that folds into one-third, and the cloth C is conveyed from the conveyor 11 of the vertical folding mechanism A to the conveyor belt 1 of the horizontal folding mechanism B.
Go to.

Therefore, a brief explanation of the vertical folding mechanism A is given below.
Is a short belt located at an end of the conveyor belt 1, 12 is a lower belt located below the conveyor belt, and which is pressed to fold the cloth C in the longitudinal direction, 14 is an end of the conveyor 1 and a lower short belt 12
In the folding guide plate for four-folding installed under, the cloth C hung from the end of the conveyor is folded into the upper and lower short belts 12 and 13 columns. From below the end of the belt toward the short belts 12 and 13. Reference numeral 15 is a guide plate stopper, and 16 is a cylinder mechanism that reciprocates the guide plate 14 about a shaft 17, and the folding timing of the cloth C is determined by the position detector 20 or the like, and the cloth C is folded in four as will be described later. 18
The drive chain 19 of the conveyor 11 shows its motor.

The horizontal folding mechanism B has a conveyor belt 1 having a width narrower than the lateral length of the four-folded cloth, the central portion of the cloth is placed on the conveyor belt 1, and the pressing plate 2 appropriately presses the cloth from above. Fold in three while carrying to the rear end of the belt. The holding plate 2 is attached to the main body 1 in a cantilevered manner at an upper portion 22 at the front end having the introduction curved surface portion 21, and the inclined portions 23 of the guide plates 3 and 4 for lifting the left and right sides of the cloth from the rear of the curved surface portion 21 are provided. It has started. The space G between the holding plate 2 and the left and right guide plates 3 and 4 has a sufficient width for inserting and removing the two folding plates 5 and 6 (Figs. 4 and 5). Plates 5 and 6 are spindles just below the belt
Rotating arms 26 and 27 that move toward and away from each other around 24 and 25
It has a bent shape or a curved surface shape that is attached to the. Numerals 28 and 29 are cylinder mechanisms for reciprocally rotating the arms 26 and 27, which are operated by a command from the position detector 30 or the like. When this command is issued, the driving of the belt 1 is temporarily stopped and the three-folding described later is performed.

Reference numeral 31 is a support for the belt 1, 32 and 33 are connecting shafts between the cylinder rods and the arms 26 and 27, and 34 is a press belt provided above the rear end of the belt 1 and the space between the conveyor belt 1 and the front is open. ,
Narrowed at the rear. Reference numeral 35 is a drive roll of the conveyor belt 1, 36 is a transmission mechanism for driving it, 37 is a motor of this mechanism, and 38 and 39 are guide pieces for sending out folding cloths.

In the above configuration, when the apparatus is operated, the tip of the cloth C moves to the end of the conveyor 11, and when detected by the four-fold position detector 20, the folding guide plate 14 which is on standby apart from the positioning 15 is on standby. About 1/4 of the tip hangs down to the position where the guide plate 14 rotates toward the positioning 15 (FIG. 6 (a)).
Approximately one half of the cloth C is returned and rotated to the position where it hangs (FIG. (B)), and thus is fed between the short belts 12 and 13 in a quadruple state (FIG. (C)). The operation of the guide plate 14 is performed by a timer or electronic control. Here, if the cloth is the towel-like cloth shown in FIG. 1, the length in the longitudinal direction, that is, the longitudinal direction is folded into four, and the state shown in FIG. 8 (a) is obtained. This is indicated by C '.

The cloth C'folded in four moves from the short belts 12 and 13 to the conveyor belt 1 as it is, and stops moving by the signal of the detector 30 when the left and right sides are lifted by the guide plates 3 and 4 (Fig. 7). (A), the folding plates 5 and 6 are inserted into the holding plate 2 from the left and right ((b), (c), (d) in the figure), and three-folded to form C ″ (FIG. 8 (b)). The folding plates 5 and 6 retreat in sequence after returning to the original position after being folded in three. Thus, the cloth which has become the target product C ″ is pressed by the press belt 34 to have a habit and then discharged to the outside of the machine. After that, when packaging is performed, a machine or manual work is required, but by connecting a packaging machine to the latter stage of the press belt 34, automation of all steps is easy.

(Operation of the Invention) As described above, according to the present invention, the fabric C to be folded is vertically folded by the vertical folding mechanism A with the specific portion to be exposed on the surface as the lowermost surface, and the fabric C is divided into four quarters of its entire length. After keeping the length of 1, hold the posture, support the central portion of the vertically folded cloth with the conveyor belt 1 that is narrower than the vertically folded cloth, press the cloth on the conveyor belt with the presser plate 2, and By lifting the left and right cloths of the conveyor belt 1 by the guide plates 3 and 4 installed on the left and right and stacking them on the center, a specific portion is accurately maintained on the lowermost surface, and three-fold in the width direction is performed.

(Effect of the invention) Therefore, according to the present invention, after the cloth is folded in four in the longitudinal direction (in the longitudinal direction), the left and right side portions are folded around the surface having the specific portion on which the company name is printed. , It is very easy to fold in three in the lateral direction, and as a result, the specific surface of the cloth can be folded by simply bringing it into the conveyor belt 1 with the surface on which the company name etc. is printed. It is possible to do vertical folding, and the total length of cloth C is 1/4.
The length of the horizontal folding mechanism B can be shortened to a quarter, and the entire apparatus can be remarkably miniaturized. During lateral folding, the cloths are pressed onto the conveyor belt 1 by the presser plate 2, so that even if they are lifted while sliding the guide plates 3 and 4 at both ends, they do not lose their shape and operate smoothly, and a high-quality folded product is sent out. be able to.
