PROBLEM TO BE SOLVED: To provide a method and a device for controlling carrying trajectory of a composite sheet, suppressing fluctuation in boundary part between a lap part and a non-lap part of the composite sheet to stably carry the composite sheet. SOLUTION: The present injection controls a trajectory in carrying the composite sheet 10, which are formed by joining a plurality of strip-shaped sheets 101, 102 through the lap parts, along a longitudinal direction. A boundary part 100 between the lap part 10A and the non-lap part 10B of the carried composite sheet 10 is detected, and the carrying trajectory of the composite sheet 10 is controlled upstream of a detection position of the boundary part 100, based on the shift of the detected boundary part 100 from a reference position.
