A stapler with a tab magazine includes a staple magazine parallel to a workpiece surface, a staple driving head and a pneumatic or electric drive for effecting a forwarding movement of the staple driver head in a direction substantially at right angles to the workpiece surface to a stapling position on the workpiece surface such that a staple from the magazine is driven into the workpiece. The driver head is controlled by a trigger and supply circuit. A tab magazine is provided along side the tab driver head for receiving a plurality of substantially planar, separate tabs in a stack of the tabs arranged each on top of the next. The magazine is arranged to support the stack in a direction generally parallel to the movement of the driver head and at a position to one side of the driver head. A spring feeds the tabs forwardly of the magazine to a forwardmost position. A drive lever pivots in a plane parallel to the surface to move a tab at the forwardmost position to the stapling position such that the staple passes through the tab at the stapling position to fasten the tab to the workpiece. The lever is driven at a timed relation relative to the driving action of the previous tab so that the next tab is held in a station at the stapling position ready to receive the staple and act as a reinforcement therefor to prevent pulling through a wrapping material. In another arrangement, the tab magazine is replaced by a roll of fiber reinforced tape so that a complete strip of tape underlies the staples and they all can be removed in a single pulling action. The strip or tabs act to locate a bag or wrapping on an article such as a stack of lumber.
