PURPOSE:To prevent occurrence of defective products or unwrapped products for improving productivity by a method wherein a notice mark is sensed, a final stage of feeding a wrapping medium is estimated and supply of an object to be wrapped with respect to the wrapping medium is stopped with specified object-supply stop timing specified before the final feed stage is reached. CONSTITUTION:When a mark sensor 32 senses an end notice mark 32 of a wrapping medium 11, a controller 31 estimates arrival of a final feed stage of the wrapping medium 11 and stops supply of an object 13 to be wrapped by an object supply device 22. By the final feed stage of the wrapping medium 11 is reached, the supplied object 13 has gone through a bag making machine 17, a vertical sealer 18 and a lateral sealer serving also as a cutter 18 of a wrapping unit 12 and carried out as a complete package 15 to be stored in a conveyer stacker. When the final feed stage of the wrapping medium 11 is reached and an end sensor 30 senses passing of the end of the wrapping medium 11, a wrapping medium feeder 16, the bag making machine 17, the vertical sealer 18 and the lateral sealer serving also as a cutter 18 stop.
