Abstract
In construction of pallets, stringers are conveyed on a conveyor in a conveying direction to a pneumatic stop assembly including a pawl. The pawl is moveably mounted relative to the conveyor by a parallelogram linkage and moveable by a pneumatic actuator between first and second heights relative to the conveyor. While the pawl is at its first height, a lower board in a hopper is pushed from a shelf by a pusher onto the stringers on the conveyor. While pushed, the ends of the board slide along and between first and second slide rails on opposite sides of the conveyor. The board on the stringers is sandwiched between the pusher and the pawl at the first height while fastened together by a nail gun. After being fastened together, the pawl is moved to its second height which does not interfere with the fastened board and stringers conveyed by the conveyor.
