Abstract
An apparatus for unfolding a bifolded mailpiece comprises a pair of pivotable receiving walls for receiving a bifolded mailpiece, a pair of receiving wall cylinders for pivotally moving the receiving walls and a pair of spreader walls for spreading the bifolded mailpiece received between said receiving walls, the spreader walls being pivotally mounted and actuated by a pair of spreader wall cylinders, a ram being provided for moving the spreader walls along a vertical axis to cooperate with the receiving walls to unfold the mailpiece.
Claims33
An apparatus for unfolding a bifolded mailpiece comprising:
- a pair of receiving walls for receiving a bifolded mailpiece, said receiving walls each comprising an upper and lower edge, each of said receiving walls being pivotally mounted along the lower edge of said receiving wall;
- at least one receiving wall cylinder for pivotally moving said receiving walls relative to each other;
- a pair of spreader walls adapted to fit within the bifolded mailpiece for spreading a bifolded mailpiece received between said receiving walls, each spreader wall comprising an upper and lower edge, each of said spreader walls being mounted for pivotable movement relative to the other wall;
- at least one spreader wall cylinder for pivotally moving said spreader walls;
- and
- a ram for moving said spreader walls along a vertical axis into the interior of the mailpiece.
An apparatus for unfolding a bifolded mailpiece comprising:
- a pair of receiving walls for receiving a bifolded mailpiece, said receiving walls each comprising an upper and lower edge, each of said receiving walls further comprising a receiving surface and an exterior surface, each of said receiving walls being pivotally mounted along the lower edge of said receiving wall;
- a pair of receiving wall cylinders for pivotally moving said receiving walls relative to each other, each of said receiving wall cylinders being coupled to one of said receiving walls;
- a pair of spreader walls adapted to fit within the bifolded mailpiece for spreading a bifolded mailpiece received between said receiving walls, said spreader walls each comprising an upper and lower edge, each of said spreader walls being pivotally mounted relative to the other wall;
- a pair of spreader wall cylinders for pivotally moving said spreader walls;
- and
- a ram for moving said spreader walls along a vertical axis into the interior of the mailpiece.
