It is configured to include.

[Action]

The feeding means moves the feeding rod, and sequentially feeds the material to be supplied, such as the filter net, which is housed in the housing cylinder in a stacked state, to a predetermined position. Further, the transfer means brings the movable head close to the accommodating cylinder, and presses the tip of the holding bar against one sheet of the material to be supplied which has been attached at the predetermined position. Since the adhesive is previously attached to the tip of the holding bar, the material to be supplied is attached to the holding bar by the above operation. The transfer means moves the movable head again to transfer the supply target material attached to the holding bar from the housing cylinder to another predetermined position.

At the transfer destination, the holding bar provided on the movable head together with the holding bar presses the supply target material held by the holding bar against the adhesive at the destination. Since the adhesive at the transfer destination has a stronger adhesive force than the adhesive at the holding bar, the material to be supplied is left at the transfer destination by pressing the holding bar.

In this way, since the material to be supplied is held by the holding bar by the adhesive, a filter mesh that is thin and easily deformed, and that is difficult to adsorb, or an article similar to this is properly held by the holding bar, It will be supplied to a predetermined position.
