But when replacing broken or otherwise damaged pins from such a tube, the operation of removing the old'pins, which are as hard as the tube, frequently results in enlarged or otherwise damaged holes in which new pins will not fit properly.
  • Fig. 1 is a side elevation, partly in section, of a picker roll constructed in accordance with'the invention
  • Fig. 2 is an end elevation of the structure shown in Fig. 1
  • Fig. 3 is an enlarged cross sectional View of a fragment of the tube shown in Fig; 1, showing a drilled and rounded hole ready to re ceive a pin
  • Fig. 4 is a similar View, showing a coated pin in operative position.
  • the old pin is driven. inwardly through its hole 6 into the interior of the tube 5, from which it is removed and discarded.
  • the coating of the pin being softer than the metal ofthe tube 5, the former yields and thehole.
