  • Patent number: 5813512
    Abstract: A stick allocator for transferring laterally aligned sticks between a holding location on a longitudinal in-feed transfer means and a high-speed longitudinal out-feed transfer means has a lower, selectively rotatable, stick lifting and translation means, disposed generally beneath the holding location, for frictionally engaging a lower surface of a stick held laterally in the holding location. Lifting the stick frictionally engages an upper surface of the stick with an upper, selectively rotatable, stick receiving and translating means, disposed generally above the holding location. The upper, selectively rotatable, stick receiving and translating means frictionally engages the upper surface of the stick and biases the stick against the lower, selectively rotatable, stick lifting and translating means.
