In addition, the cutting blades 7 of the three cutting devices 9-1 to 9-3 are operated again to operate the remaining portion of the cutting tube 3a (Fig. 12 (a)). In addition, the cut tubes 19a-3, 3a-4, and 3a-5 can be removed and transported by the discharge-side table 6a after removing the cutting heads 19 (Fig. 12 (b)). After the cut pipes 3a-3, 3a-4, and 3a-5 are completely discharged, the subsequent pipes 3b are carried from the entry-side table 5a to the cutting line 2a on the cutting table 4a. Subsequent tubes 3c are transported to the entry-side table 5a, and stand by until the previous tube 3b is cut and discharged (Fig. 12 (c)). Thereafter, the same procedure as the above-mentioned tube 3a is repeated, and the tube 3c and the like are cut and discharged. In the cutting line 2a of the above-mentioned equipment, all subsequent tubes 3b stand by on the entry-side table 5a until the previous tube 3a is cut and completely discharged from the cutting line 3a, and are not transported into the cutting line 2a. Therefore, only the cut-off period of the carry-in time from the standby position to the cut-off position is increased. In the above-mentioned cutting line 2a, the rotation speed of the conveying roller is controlled by a driving motor of each table. Therefore, the pipe is moved across the two tables at different speeds such as the forward and stop of the tube. When the tube is broken, slipping occurs between the table tube on one side and the transport roller, which can damage the transport roller or tube. Therefore, because the above method is adopted to avoid the above-mentioned damage, the pipe 3a on the cutting line 2a is discharged and then the subsequent pipe 3b is carried in. Therefore, only the paper size is increased to apply the Chinese National Standard (CNS) A4 specification (210X297 mm) ( (Please read the notes on the back before filling out this page)
