By rotating the screw shaft 37 of the swing drive mechanism 30, the basic angle φ of the adjustment arm 12 with respect to . By rotating the splicer feed motor 49 and driving the timing belt 27, the splicer 13 is moved to the standby position S.
The cut sheet body 5a is moved backward at a high speed from As shown by the line, the tip portion 21 of the adjustment arm 12 is swung in the transport direction H so that the basic angle φ is larger than the inclination angle θ by the angle α. Here, the angle α is an angle corresponding to the motor rotation speed required for the angle adjustment motor 38 to rise to a constant speed after starting, and is an angle corresponding to the motor rotation speed required for the angle adjustment motor 38 to reach a constant speed after the angle adjustment motor 38 is started. The motor 38 is set so as to reach a predetermined rotational speed when the other front end 3 of the cut sheet body 5a is detected. When the retraction speed switching sensor 48 passes approximately the center of the front end 3 of the supplied sheet body 5a and detects the front end 3, the splicer feeding motor 49 causes the splicer 13 to retract in response to a command signal from the cough sensor 48.

A rectangular or parallelogram-shaped cut sheet body 5a in which the front and rear edges 3 and 4, which are the short sides, are inclined at predetermined inclination angles θ and θ with respect to the left and right edges 1 and 2, which are the long sides. is taken out from the starting end side of the conveyance path 11 and conveyed to the terminal end side, and the front end 3 of the cut sheet body 5a being conveyed is fixed to the rear end portion 4 of the belt-shaped sheet body 5b waiting at the terminal end side. This is a joint device for sheet bodies that are joined together at a superposition margin, and includes a suction device 6 for suctioning and holding the front end 3 of the cut sheet body 5a, and a left and right side for detecting the rear end 4 of the belt-like sheet body 5b. a pair of belt-shaped sheet body rear end detection sensors 7 and 8;
A pair of right and left cut sheet body front end detection sensors 9 and 10 for detecting the front end 3 of the cut sheet body 5a, and a joint portion between the front end portion 3 of the cut sheet body 5a and the rear end portion 4 of the band-shaped sheet body 5b. a joint angle adjustment arm 12 which is equipped with a joint press device 15 for pressing the joint angle adjustment arm 14 and is swingable around the pivot joint 19;
2. A joint device for a sheet body, characterized in that a splicer 13 is provided with a lifting device 32 for lifting and lowering the splicer 2, and is movable forward and backward along the conveyance path 11. 3. The conveyance path 11 includes an air table 16 and a cut sheet body position regulating member 1 disposed along the air table 16.
7, and a guide rail 18 that guides the splicer 13 moving forward and backward, and the air table 16 is connected to the cutting sheet body position regulating member 1.
3. The seat body joint device according to claim 2, wherein the seat body joint device is inclined downwardly in the direction of 7.
