  • Patent number: 8950449
    Abstract: A cutter head for surfacing a flitch, the cutter head including a shaft, a blade non-rotatably mounted on the shaft, wherein the flitch is surfaced by rotating the blade, a bushing including a bore, wherein the shaft runs through the bore, wherein a flange is eccentrically formed about the bore, a guide mounted on the flange of the bushing, wherein the flange axially offsets the guide with respect to the shaft, wherein the guide is arranged to support the cutter head against the flitch while the cutter head is surfacing the flitch, and wherein a radial distance between a tip of the blade and the guide determines a cutting depth of the cutter head, and wherein due to the guide being mounted on the eccentrically formed flange, the radial offset is determined based on a rotational orientation of the bushing about the shaft.

  • Patent number: 7871070
    Abstract: A conveyor conveys sheets and deposits the sheets at a location to be stacked. The conveyor includes a sensor for determining the presence of a sheet before the sheet arrives at the location. A controller is coupled to the sensor and responsive to sensor inputs for controlling a movable support for projecting into a projected orientation to receive the sheets as the sheets exit the conveyor. The movable support moves to a retracted orientation to assist a stack to be withdrawn therefrom.
