  • Patent number: 6283353
    Abstract: A press roll device for applying pressure on a piece of wood moving along a path. The device has a frame mounted in proximity to the path of the piece of wood and a lower and an upper arm both pivotally connected to the frame. A roller is rotationally mounted on the end of the lower arm and a jack is resiliently connected to the corresponding end of the upper arm. A bag of compressed air is disposed between the ends of the lower and upper arm, resiliently separating the roller and the jack. In this manner, the bag of compressed air absorbs the vibration of the roller caused by unevenness in the piece of wood, at least partially.

  • Patent number: 6189682
    Abstract: The present invention provides an automatic lug loader to place blocks on each lug on a lug conveyor in a finger jointing machine. The lug loader includes a support structure with a control station and a feed table. A powered loading conveyor overlies the support structure with an infeed end disposed over the control station. The loading conveyor extends downstream to an outfeed end which is disposed over the upstream end of the lug conveyor. A powered adjuster is connected to the loading conveyor and shifts the loading conveyor toward and away from the control station to selectively grip a block.
