Then, as shown in Fig. 8, (10) the special insertion piece (18a) enters into the first slit (4-'l) while pulling in the towel fabric (A).As a result,
The end of the terry cloth roll is folded in half within the first slit 04.

Next, the piston rod of cylinder θQ is extended. Then, only the insertion piece (18a) is pulled out, leaving the folded portion (B) in the first slit Ial. In this state, the tip of the insertion piece (18a) has entered the folded part 9 (B), so the piston rod of the cylinder Q1 is reduced and the insertion piece (18a) is rotated in the direction of the arrow (E). After the piston rod is moved, the piston rod is extended and the insertion piece (18a) is rotated in the direction of the arrow. As a result, as shown in FIG. 9, the tip of the insertion piece (18a) comes into contact with the upper surface of the folded portion 9 (B). Next, operate the cylinder handle (c) of the pushing and spreading mechanism Qυ, and use the take-out blade to spread out both ends of the lower surface of the bifold part (Bl).Next, extend the piston rod of the cylinder a41.Then, the shaft body (26+) It is pushed up, and the force of the upper slit shape q is rotated upward by Δ with the hinge θ4 as a fulcrum, and the clamping of the folded part 9 (B) is released. Since there is some play, plate f2 is pushed up a little after the shaft body !2f5+ is pushed up.

and both slit forming members QI4 are raised, and the first
As shown in Figure 0, the folded portion (B) is bent upward by the lower slit forming member O, and the bent portion is supported by the pressing head (C). At this time, due to the extension of the piston rod of the cylinder Q4), the υ axis 69
is pushed up, and the stopper ff111 is rotated in the direction of the arrow (toward) via the swinging link ring and the connecting rod (2). Next, the piston rod of cylinder Q9 is extended.

Then, the pinion (B) is rotated in one direction via the arm (A), the horizontal axis (■) is moved in the direction of the arrow (B) via the rack (to), and the lower slit forming member (14 and the pressing head (The 7 proverbs move above the table θη, and as shown in FIG. 11, the pressing head T4 causes the folded portion (Bl) to be folded into three using the tip of the insertion piece (18a) as a fulcrum.Next, When the piston rod of the cylinder θQ is extended, the piston rod is extended to the maximum due to the absence of the stopper 1511, and the tip of the insertion piece (18a) is pulled out from the trifold portion (C).Next, the cylinder Shrink the piston rod and insert the insert plate (to) with the arrow (ho)
Rotate it in the direction of the tape) to release the upper part of the Vo sword.

Next, the towel presser (A) is lowered by the cylinder Oυ to press down the tri-folded part (C), and the upper ends of the tri-folded part (C) are spread apart by the selvedge pieces that move diagonally upward. As a result, the three-fold υ portion (C) of the terry cloth turns as shown in Figure 13. Next, the towel fabric (4) is sent to the sewing section by the conveying action of the towel presser (E), and the trifold portion (C) is sewn.

Effects of the Invention As described above, according to the present invention, even though the towel fabric is soft and has no stiffness, it can be folded into three, and the process can be carried out completely automatically, which saves time and effort. It does not take much time, can be mass-produced, and can reduce costs.
