  • Patent number: 6374988
    Abstract: An accumulating conveyor for elongated stock, such as tubes, rods, bars and similar articles. At least three independently operable conveyor banks are arranged for sequentially transferring elongated stock from one bank to the next. Each conveyor bank includes a number of elongated substantially parallel racks which extend in the direction of desired conveyance and each rack has at least two adjacent rows of teeth extending longitudinally along the rack. The teeth of one row of each rack are staggered with respect to the teeth of the other row and a drive is connected to alternately raise one row of teeth above the other whereby elongated stock placed transversely on one end of the racks will be moved to the other end of the racks for offloading or transfer to an adjacent conveyor bank.

Boring and cutting elements on the tool are simultaneously disengaged from the pipe end in a controlled manner to taper out the cuts and permit rapid retraction of the tool without contacting the finished surfaces and possibly producing a scratch mark.
