The seven pairs of rolls 41 to 47 are arranged along the conveying direction of the belt-shaped three-layered gum 12 and sequentially convey the belt-shaped three-layered gum 12 from the upstream side to the downstream side.

The rotational speeds of the seven pairs of rolls 41 to 47 are set so that the rotational speed of the circumferential surface of the roll is relatively slow as compared with the pair of rolls on the downstream side in the conveying direction.

For example, assuming that roll pairs of the same diameter are used, the rotational speed of the roll pair 41 is V1, the rotational speed of the roll pair 42 is V2, The rotation speed of the roll pair 44 is V3, the rotation speed of the roll pair 44 is V4, the rotation speed of the roll pair 45 is V5, the rotation speed of the roll pair 46 is V6, Is V7,

V1 <V2 <V3 <V3 <V4 <V5 <V6 <V7

.

While the belt-like three-layered gum 12 is being conveyed to the plurality of roll pairs 41 to 47 by sequentially increasing the rotation speed of the roll pairs 41 to 47 along the conveying direction in this manner, Tensile force is applied in the direction, and the thickness thereof is gradually thinned.

10, a band-shaped three-layered gum (hereinafter referred to as &quot; band-shaped three-layered gum &quot;) which is output from the nozzle 11 of the main extruder 10 is disposed on the upstream side of the rolling device 40 A thickness sensor 48 and a width sensor 49 are provided for measuring the thickness and width of the wafer 12. The thickness sensor 48 and the width sensor 49 can be realized by, for example, a laser sensor using laser light.

A width sensor 59 for measuring the width of the rolled band-shaped three-layered gum 12 is provided on the downstream side of the rolling device 40 in the conveying direction of the belt-shaped three-layered gum 12 have. This width sensor 59 can also be realized by a laser sensor.

In the apparatus of this embodiment, the discharge amount of the outer layer gum 3 pushed out from the main extruder 10 is controlled based on the output of the thickness sensor 48 and the width sensor 49 provided on the upstream side, The thickness and the width of the band-shaped three-layered gum 12 output from the nozzle 11 are adjusted to be a desired value.

The output of the width sensor 59 provided on the downstream side may be reflected in the discharge amount control of the outer layer gum 3 extruded from the main extruder 10.

It is also possible to control the ratio of the rotational speeds of the seven pairs of rolls 41 to 47 based on the output of the width sensor 59 and to control the final width of the band- It is possible.

Fig. 11 is a diagram schematically showing the configuration of the apparatus for realizing the width adjustment described as step S8 in Fig. 2. Fig.

Figs. 12, 13, and 14 are diagrams showing the configurations of the portions I-I, II-II, and III-III in Fig.

Referring to Figs. 11 to 14, the width adjusting device is realized by the one side cutting device 50. Fig. The one side cutting apparatus 50 has a linear guide surface 51 guiding along one side of the rolled band-shaped three-layered gum 12. The guide surface 51 is provided with a pair of conveying rollers 52 disposed on the upstream side thereof as viewed in the conveying direction of the belt-shaped three-layered gum 12, and a pair of conveying rollers 52 disposed on the downstream side thereof, (53). The rolled band-shaped three-layered gum 12 is fed from a pair of conveying rollers 52 toward a pair of conveying rollers 53 and extended in a straight line. At this time, one side face of the band-shaped three-layered gum 12 is guided by the guide face 51, and the position of one side face is a predetermined position as viewed in the width direction.

Between the conveying roller 52 and the conveying roller 53, a receiving roller 57 and a rotary blade 55 that rotates about the rotating shaft 54 are disposed. The rotary blade 55 has a gap W (the interval W is the same dimension as the width W required as the width of the rolled band-shaped three-layered gum 12) from the guide surface 51 And is provided so as to be able to cut the other side surface of the band-shaped three-layered gum 12 along the feeding direction.

More specifically, the rotary shaft 54 extends in a direction perpendicular to the guide surface 51, and a rotary blade 55 extending in a direction orthogonal to the rotary shaft 54 is attached. Therefore, when the other side surface of the band-shaped three-layered gum 12 to be conveyed protrudes beyond the width W required for the band-shaped three-layered gum 12 (the width (W) And the other side is cut off by the rotary blade 55. In this case,

The width of the opening for the outer layer 17 and the opening for the middle layer 20 and the rolling amount of the rolling device 40 and the width of the strip 3 gum 12 detected by the width sensor 59 It is theoretically possible to control the width of the rolled band-shaped three-layered gum 12 to a desired constant width W. However, the actual production, the width W 'of the rolled strip-like three-layered gum 12 tends to be wider or narrower or change than the required predetermined width W. Therefore, the one side cutting device 50 functions as needed, and the other side of the band-shaped three-layered gum 12 is cut by the rotary blade 55 and the receiving roller 57, The gum 12 is adjusted in its width to a predetermined width (W). Specifically, the width (') of the band-shaped three-layered gum 12 is intentionally made wide and the other side of the band-shaped three-layered gum 12 is cut by the one side cutting device 50, (W).

Fig. 15 shows a three-layered gum semi-finished product 6 cut as a semi-finished product and described in step S9 in Fig. 2 (step S9).

As shown in Fig. 15, the three-layered gum semi-finished product 6 has a length (L 0 ) of one final product in the short side direction dimension W thereof. The dimension L of the three-layer gum semi-finished product 6 in the long-side direction is obtained by cutting the semi-finished product 12 into final products (three-layer gum 1) of n pieces (n is an arbitrary natural number) that is a length (L = W 0 × n) .

By cutting the band-shaped three-layered gum 12 thus rolled into a semi-finished product as an intermediate stage of the production, the yield at the time of cutting the final product, individual packaging, and box packing is improved, And manufacturing becomes possible.

In the above description of the embodiment, such a manufacturing apparatus has been described with respect to the production of three-layer gum. However, the rolling apparatus 40 and the one side cutting apparatus 50 in this manufacturing apparatus are not limited to the manufacture of three- The present invention can also be applied to the production of ordinary single-layer plate-like gum.
