し、製造価格が上昇するなどの難点を有していた。In cutting a sheet laminated in this way into a predetermined size, in order to cut the laminated sheet into a sheet-like sheet, a thick band-like film bonded is used. To cut with the paper
Rigidity is required for the cutting part, which increases the size and promotes the wear of the cutter, which increases the frequency of replacement, making maintenance difficult.In addition, continuous feeding with the ends abutted and lamination When the cut sheet is cut from the butt portion, it is necessary to accurately match the running position of the cutter with the butt position. Therefore, it is necessary to detect the stop position of the butt portion of the laminated sheet and to determine the positioning accuracy. In addition, since the posture at the time of feeding a sheet is required to be accurate, operability is difficult, the structure is complicated, and the manufacturing cost is increased.

決定的なものがなかった。In the case where the laminated sheet is stopped at the cutting position and the cutter is moved in a direction perpendicular to the running direction of the laminated sheet at the overlapping portion to cut only the strip-shaped laminated film, this type of sheet is used. Conventionally, various shapes and structures of the cutter have been adopted.These are that the cutter comes off from the cut portion during the cutting traveling, and also cuts the sheet itself in addition to the strip film, or In the middle of cutting the strip-shaped film, it was impossible to cut the strip-shaped film, and the strip-shaped film was jammed with the cutter, and there was no definitive method for reliably tearing only the strip-shaped film.

の設計変更をなし得ることは勿論である。As is apparent from the above-described embodiment, according to the present invention, continuous feeding is performed by overlapping the rear end of the preceding sheet with the front end of the succeeding sheet by a predetermined amount. And a laminating section for laminating a strip film on the sheet is provided, and a transfer section for transferring the laminated sheet sent from the processing section is provided, and only the strip film of the laminated sheet is provided in the transfer section. A cutting section is provided along the overlapped end, and the overlapped end of the sheet is detected just before the cut section in the traveling direction of the laminated sheet, and is moved by a predetermined distance to be positioned at the cutting position. A tension detecting unit is provided between the laminating unit and the transfer unit, and the tension of the laminated sheet at the cutting position is adjusted by adjusting the slack of the laminated sheet continuously transmitted from the laminating unit. It is provided the tension control device for controlling constant, lamellar cutter substantially triangular with a pointed towards run the row direction of the superposed portions of the laminated leaf paper stop positioned to disconnect position downward inclination, superimposed laminate Single leaf
The lower edge of the paper is pushed down and opened, inserted and locked to the side edge of the band-shaped film, and this is moved in a direction perpendicular to the sheet running direction so that only the band-shaped film is laminated on the laminated sheet. The configuration in which the sheet is torn along the edge enables the laminated sheet to be cut with a simple configuration and surely, and has an excellent effect such as a reduction in manufacturing cost. The preferred embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and it is needless to say that various design changes can be made without departing from the spirit of the present invention.
