Abstract: An automatic nailing head for an automatic nailing device is disclosed. A nailing head including a means for causing an angle between a central shank axis of the nail and a central axis of the throughbore to gradually decrease as the nail passes through a nail feed channel and into the throughbore is described. A picker plate capable of receiving a nail when in a first position and dropping the picked nail when moved to a second position is described. A nailing head with a quick release body portion for unjamming the heads without the use of tools is also described.

Abstract: Bulk nails from a single outlet track of a vibrating feedbowl are selectively diverted into a plurality of nail tracks. During each nailing operation of a pallet-making machine, one nail from each track is picked from the track and delivered to a nail-driving chuck. The presence of nails in the track is sensed, and the selective filling of the tracks is based upon the presence or absence of nails in the individual tracks.
