ABSTRACT:
Apparatus for placing a sheath on a vertically oriented elongated member, the sheath having an open end for receiving the elongated member, comprises an upright magazine for containing a stacked plurality of the sheaths with the openings thereof oriented downwardly, a downwardly extending passage having an upper end communicating with the magazine and a lower end having a discharge opening arranged on a vertical axis with which the elongated member is to be aligned for being received in a respective said sheath discharged from the discharge opening onto the elongated member, a first gate defining the boundary between the magazine and the passage and for blocking transit of the sheath from the magazine into the passage and a second gate below the first gate a distance about equal to the length of a respective said sheath for blocking transit of the sheaths to the discharge opening of the passage, whereby the sheaths may be individually discharged by gravity onto respective said elongated members consecutively positioned in alignment with the axis by a cycle constituting closing the first gate of the loaded apparatus while the second gate is closed thereby to isolate the lowermost of the sheaths between the first and second gates, then opening the second gate thereby to permit the lowermost one of the sheaths of the stack to drop out of the discharge opening over the elongated member aligned with the axis, then closing the second gate and opening the first gate to permit the now lowermost one of the sheaths of the stack to descend onto the second gate, and repeating this cycle for each of the sheaths which is to be deposited on a respective elongated member. Apparatus for assuring the straightness of the elongated member thereby to facilitate the placing of a sheath on the elongated member comprises straightening means movable between an open inoperative condition and a closed operative condition for laterally engaging the elongated member at first, second and third consecutive positions along the length of the elongated member, the engaging at the first and third positions, on the one hand, and the engaging at the second position, on the other hand, being in opposition and holding the elongated member in a straight configuration, and means for effecting movement of the straightening means between the inoperative and operative conditions thereof.
