  By the way, in the tape sticking device described in Patent Document 1, since the two tape sticking aggregates are arranged in a position shifted in the sheet transfer direction, the roll body is replaced with the reel of the tape sticking unit. Cannot be performed from the same position, and it takes time to replace the roll body, and there are still points to be improved.

  In addition, it is necessary to provide a work deck for the operator to get on and off for each of the two tape affixing assemblies, and furthermore, because the two tape affixing assemblies are arranged before and after the sheet transfer direction, The size of the tape applicator is increasing, and there are still points to be improved in reducing the size.

  Furthermore, because the tip of the tape that is stopped by the swinging of the touch roll is attached to a sheet that runs in one direction, the tape starts to run suddenly at the same time as the application, and a large tension is applied to the tape. May be cut off or peeled off, and there are still points to be improved.

  An object of the present invention is to provide a small tape applicator capable of performing an exchanging operation of a roll body at the same position and capable of adhering without applying excessive tension to the tape.

  In order to solve the above problems, in the present invention, a plurality of reel units having roll body mounting reels are arranged in a line in the width direction of the sheet on a sheet traveling in one direction. The reel unit is a support that can be independently adjusted in the width direction of the sheet, a plurality of guide rolls for guiding the tape drawn from the roll body on the reel toward the upper surface of the sheet, and a lead piece connected to the leading end of the tape A plurality of tape guide units that have a lead piece feeding device capable of holding the tape in a suspended state, and at the start of tape application, the lead piece feeding device accelerates the lead piece to a position where it comes into contact with the upper surface of the sheet. Are divided into two groups by half, and the plurality of tape guide units of each group have a sheet width below the plurality of reel units. A group of tape guide units grouped by providing a position adjusting device for shifting the position of each of the plurality of tape guide units in the width direction of the sheet. The touch rolls that are moved up and down with respect to the sheet and press the lead piece and the tape against the sheet in the lowered state are used.
