The seaweed 18 is arranged in front of the rice block R as shown in FIGS. 1 and 9 while being guided by the guide portions 23 a and 23 a ′ of the seaweed guide 23. Thereafter, the solenoid PL1 is driven to close the blade of the cutter 22, and the laver 18 is cut (P7 ', P8' in FIG. 15).

Next, the motor M2 is driven to rotate the rotating disk 5 by one pitch in the direction of arrow C, and the hole 5a moves to the laver winding position S4 (FIG. 15P4). In this transition process, the rice molding elevating receiver 13a is
Since a ″ travels on the high position portion 15b of the cam 15 having the same height, the height of FIG. 6C is maintained.
The rice block R also moves to the laver winding position S4 in a state where the rice block R also faces the rotating disk 5. Therefore, during this transition process
The rice block R is a guide portion 23 of the laver guide guide 23.
a, 23a ', and at this time, the laver 18 adheres to the front side of the rice block R in the traveling direction. At this time, the seaweed 18 is securely attached to the rice block R by the adhesive force of the rice block R itself. Then, the rotating disk 5 is positioned at the seaweed winding position S.
When the number reaches 4, the rice chunk R is located in the middle of the rice chunk receiving portions 27 and 27 'as shown in FIG. At the timing of the step P4, first, the motor M4 is driven to rotate the driving screw 31, and the rice lump receiving portions 27, 27 'are driven.
Are driven in the directions approaching each other (the directions of arrows I and J) to wrap the rice block R from the left and right directions as shown in FIG.
5P9 '). Thereby, the laver 18 adheres to the left and right side portions of the rice block R. Next, the driving of the motor M4 is stopped,
By driving the rotary solenoids PL2 and PL2 ', the laver retainer pieces 29 and 29' are rotated in directions approaching each other (arrows M and N) with the drive shafts 28 and 28 'as supporting shafts, and the rear surface of the rice block R The laver 18 on the side is attached to the rear side of the rice block (see FIG. 13C). At this time, the solenoid is driven in the order of PL2 and PL2 ', thereby driving the laver retainer pieces 29 and 29' alternately in the order of Fig. 13C (Fig. 15P10 '). Thereby, the end of the nori 18 is stuck on the rear side of the rice block R with some overlap,
The seaweed 18 is wrapped around the rice block R, and a so-called warship winding state is completed (FIG. 4D). Thereafter, when the drive of the rotary solenoids PL2 and PL2 'is released, the laver retainer pieces 29 and 29' are rotated and returned in directions (arrows O and P directions) separated from each other by the urging force of a spring (FIG. 13 (d)). ), FIG. 15P11 ′), and driving the motor M4 in the reverse direction to drive the rice lump receiving portions 27, 2
7 'are driven in directions away from each other (directions of arrows K and L) (FIG. 13 (e), FIG. 15P12'). By this step, a so-called warship winding R '(without tools) is completed on the rotating disk 5.

Next, the motor M2 is driven by one pitch, and the hole 5a moves to the unloading position S5 (see FIG. 15P).
5). Also in this transition process, since the roller 13a ″ of the rice molding elevating and lowering receiver 13a runs on the cam 15 (the high position portion 15a) having the same height, the height of FIG. 6C is maintained. With the rice lumps R 'remaining on the rotating disk 15, the process moves to the unloading position S5. Here, the worker or the like unloads the finished warship winding R' by hand, and the warship winding R The various materials are placed on the upper surface of the 'to complete the warship winding (S13' in FIG. 15).

Next, the motor M2 is driven by one pitch, and the hole 5a moves to the transition position S6 (see FIG. 15P).
6) Further, by driving the motor M2 by one pitch, the hole 5a returns to the rice supply position S1, whereby one process ends (FIGS. 15P6 to P1). In the process of moving from the transition position S6 to the rice supply position S1, the rice molding lifting and lowering receiver 13a has its roller 13a ″.
Descends on the descending portion 15c of the cam 15, the receiving surface 13a 'is inserted into the hole 5 at the rice supply position S1.
The position returns to the position shown in FIG. Thus, the manufacturing process of one warship winding is completed, but in actuality, rice is sequentially supplied to each rice forming hole 5a at the rice supply position S1 every time the rotary disk 5 rotates one pitch. The processing is performed one after another at each of the subsequent positions S2 to S6, and the rice lump R ′ (warship rolls) wound with laver is supplied to the unloading position S5 at every one pitch. The rice chunks R 'sequentially sent to the unloading position S5 are sequentially unloaded.

(A)) Then, the receiving portions 40 and 40 'approach each other in the approaching direction so as to fit the size of the rice block R, and the laver 18 is attached to both sides of the rice block R (FIG. b)) Then, the shutters 41, 4 provided at the rear ends of the receiving portions 40, 40 ', respectively.
1 ′ is alternately closed in the order of (c) in FIG.
Is folded into the rear side surface of the rice chunk R and attached to the side surface (FIG. (C)), and then the shutters 41 and 41 ′ are opened (FIG. (D)), and the rice chunk receiving portions 40 and 40 ′ are opened. Are opened in a direction away from each other, so that the warship winding R 'can be completed on the rotating disk 5.

FIG. 17 shows a pair of laver winding rollers 4 each having concave portions 42b, 42b 'on the surfaces facing each other, and being rotatable about axes 42a, 42a' and having a substantially elliptical shape in plan view.
17 are arranged so that the rice chunk R enters the center between the rollers 42 and 42 '(FIG. 17).
(A)) Then, the rollers 42 and 42 'are moved in a direction approaching each other to attach the laver 18 to the side surface of the rice block R (FIG. 17 (b)). By rotating in the X direction, the seaweed 1
8 is wrapped around the rice block R (FIG. 3 (c)), and then the rollers 42 and 42 'are rotated in the opposite direction Y so that the other end of the laver 18 is rotated by the other roller 42. Is wound around a rice loaf R (FIG. 4D), and then the rollers 42, 42 'are opened in a direction away from each other to complete the warship winding R' on the rotating disk 5.
