Several improvements to an unloading and stacking mechanism for an automatic precision blanking machine are presented. Such mechanisms conventionally have at least one laterally arranged backstop support bar, a pair of vertical side guides and one or more vertical elongated dividers to axially align cut-to-length pieces of sheet metal, and one or more backstop assemblies to transversely align the distal edges of the severed pieces of sheet metal. The improvements include: (1) a lightweight hand-removable adjustable-length backstop for helping align short severed pieces of sheet metal that extend over only part of the pallet underneath; (2) a movable adjustable top guide for receiving and supporting distal end portions of one or more relatively flat thin flexible sheets of metal initially advanced out of and to be severed by the precision blanking machine; (3) hand-removable lightweight side guide assemblies for restraining side edges of extra short pieces of severed sheet metal successively being advanced out of the precision blanking machine; and (4) an improved backstop assembly having extended vertical face surfaces on the piece-contacting face members to help ensure the initial few severed pieces of cut-to-length pieces of sheet metal to drop to a pallet to begin forming a stack do not end up sliding partially under the contact members.
