Abstract
A method of producing bearing pulleys for conveyer belts and roller gravity conveyers in which the bearing pulley includes a cylindrical portion and common central pivot pins secured to the cylindrical portion by a hub or roller base, which comprises providing a cylindrical pipe of a desired bearing pulley diameter, tapering the end portions of said pipe in a truncated configuration by non-cutting cold deformation down to the diameter of the pivot pins, and subsequently inverting the tapered end portions of the pipe centrally within the cylindrical portion of the pipe a distance sufficient to provide the desired spacing between the ends of the pulley.
