Abstract: A method of preparing flat articles for sorting includes the steps of: (1) receiving a bundle of flat items to be sorted, the bundle being wrapped with a flexible film such that the film forms an enclosed package of flat items, (2) placing the bundles on a substantially horizontal, substantially frictionless work surface, moving the bundle adjacent at least one film slitter, the film slitter being automatically activated when the bundle is moved adjacent the film slitter, (3) removing the cut film from the flat items, and (4) stacking the unbundled flat items in a cartridge.

Abstract: A wrench body pivotally connected to an end of a reciprocating power source, a tool head assembly attached to the opposite end of the reciprocating power source, which would include a tool head, having an aperture for the work piece, tracking arm attached to the tool head and for being matingly slideable into a surface of the wrench body; a retainer ring having at least two retainer grooves; at least two roller drive pins positioned within each of the retainer grooves, and biased away from the retainer rim by a leaf spring inserted between the wall of the rim and each drive pin; a ratcheting gear operative attached to the tool body and positioned in the aperture for connecting the work piece, the ratcheting gear having a plurality of axially aligned and beveled channels along the perimeter of the gear so that one of the drive pins are received into at least one of the channels, in order to achieve the ratcheting function, and through a movement of 15.degree.
