３がクーリングドラム８により冷却されているため）。As shown in FIG. 1, the conventional calender device alternately rotates heating rolls 1 to 4, which are successively arranged in an inverted manner while sequentially facing each other, in opposite directions. The thermoplastic resin 5 passed between the second heating roll 1.2 is rolled while being sent in order to the third and subsequent heating rolls 3.4 to form a sheet 6, and this sheet 6 is passed through the guide roller 7.
After being sent to a cooling drum 8 through a cooling drum 8 for cooling, it is wound up by a winding roller 9. In this case, the rolled sheet 6
Conventionally, in order to make the sheet width uniform, both ends of the sheet 6 are cut by slitters 10 placed on the left and right sides of the circumferential surface of the fourth heating roll 4, or the ends of the sheet 6 are cut by a cooling drum 8.
Both ends of the sheet 60 were cut by a slitter 11 placed at the rear end of the sheet. Then, in order to reuse the cut sheet scraps 12 and 13 as sheet raw materials, the sheet scraps 12 are returned by the first pair 14. Second heating roll 1
It is directly returned to the top of ゜2 (because the sheet scraps 12 are heated by the heating roll 4), -10,000, sheet scraps 13
In this case, they were transported by air to a Banbury mixer or mixing roll, crushed, re-kneaded, and then reused (sheet scraps 1

有していた。However, in the former case (when cut by the slitter 10), the width of the sheet on the heating roll 4 fluctuates, so a narrow part is formed in the sheet scraps 12, and the sheet scraps 12 are cut during return by the conveyor 14. There was a problem that the return process could not be carried out smoothly. In the latter case (cutting with the slitter 11), the sheet scraps 13 must be transported by air and kneaded again.
There was a problem in that equipment costs such as air transportation and crushing equipment were high.
したがって、この発明の目的は、シート端材のシート原

樹脂原料として再使用される。The operation is explained below. (6) That is, the thermoplastic resin 22 is inserted into the four resin stock parts 18, and the heating rolls 1 to 4 are driven to rotate. Then, the resin 22 passes between the first and second heating rolls 1.2 and passes through the third. It is sent in order to the fourth heating row/L'3.4 and is rolled from the sheet 6 to form a sheet 6, and the slitter 15
, 15'. The V-) 6' cut to a predetermined width in this manner is sent to a cooling drum by a guide roller rough and cooled, and then wound into a cylindrical shape by a winding roller. On the other hand, Su IJ Tsuta 1.5
, 15', the sheet scraps 12 are returned to the resin stock recess 18 by the return conveyor, and
Reused as resin raw material.

６節される。That is, when the sheet end position 6a moves inward from the internal photocell 20 (the sheet width decreases), the internal photocell 20
operates, causing the motor 19 to rotate the threaded rod 20 in the forward direction,
The left and right stock guides 17° and 17' are spaced apart from each other. Since the width of resin feeding between the second heating rolls/l/1°2 is increased, the sheet width on the circumferential surface of the fourth heating roll 4 is increased. On the other hand, if the sheet) Q section position 6a comes to the outside of the external phototube 21 (the sheet width increases)
, the external photocell 21 operates and the motor 19 causes the threaded rod 1 to
6 is reversely rotated, the left and right stock guides 17° and 17' approach each other, and the first stock guide 17. Since the width of resin feeding between the second heating row/L'1°2 is narrowed, the sheet width on the circumferential surface of the fourth heating roll 4 is reduced. thus,
The width of the sheet scrap material 12 is always within a certain range!
Verse 6 is given.

設備を一切不要とできて、設備費用も安価にすむ。In this way, the minimum height of the sheet scrap material 12 can be determined by the arrangement position MVC of the internal photocell 20, so the internal photocell 20
The position of the sheet scraps 1 must be determined appropriately in advance.
By setting 2 to a predetermined width 4 at all times, it is possible to prevent the sheet offcuts 12 from being cut during return work by the return conveyor, and the sheet offcuts 12 can be smoothly reused as sheet raw materials. can. In addition, sheet scrap material 12
is not a cut of the cooled sheet 6, but a cut of the sheet 6 heated on the circumferential surface of the fourth heating row/L/4. There is no need for this at all, and equipment costs are low.

．． Left and right threaded rods 23 and 23' parallel to the low μ axis are arranged at left and right positions above 2, and these left and right threaded rods 23
, 23' are screwed into left and right stock guides 24 and 24', respectively, and left and right motors 25 and 25' are installed at the outer ends of the left and right threaded rods 23 and 23'. , 25' for left and right threaded rods 23 and 23'
By reverse rotation drive, left and right stock guides 24, 24
' is configured to slide outward and inward along left and right threaded rods 23 and 23', respectively. On the other hand, on the outside of the surfaces of the left and right slitters 15 and 15', internal and external phototubes 26 and 27 for detecting the left edge of the sheet and internal and external phototubes 26 and 27' for detecting the right edge of the sheet are respectively disposed. Inspection (9) 1 output internal/external photocell 26.27 is the 4th heating row)
v4 When the left end position of the seat on the circumferential surface 6 a f is detected, the left motor 25 is driven in forward and reverse rotation, respectively, and
When the inner and outer phototubes 26' and 27' for detecting the right edge of the sheet detect the right edge position 6b of the sheet on the circumferential surface of the fourth heating roll 4, the right motor 25' is rotated forward and backward, respectively #AwJ
Configure it to do so. The other plantings are the same as in the above example.
