  • Single-pass pallet disassembler with self-adjusting head
    Patent number: 5243751
    Abstract: An apparatus for unnailing wood pallets includes a frame, a first cutter assembly and a second cutter assembly positioned vertically above the first. The first cutter assembly includes a pair of elongated horizontal support arms supporting a cutting head at one end, downwardly biasing springs at an opposite end and a pivot between the ends. The second cutter assembly includes a pair of elongated horizontal support arms supporting a second cutting head at one end and a pivot at an opposite end that is coaxial the pivot of the first cutter assembly. The second cutter assembly is biased upwardly by springs between its support arms and those of the first cutter assembly. A stringer return member is horizontally movable with a pallet-moving cradle and includes a member which is pivotally mounted to the cradle at one end and has a follower at an opposite end to follow a track that moves with the support arms in order to keep the member positioned between the pair of support arms.
