An envelope inserting machine has a feed path for envelopes which includes an envelope inserting position and means for feeding successive envelopes to that position. Envelope throat opening claw assemblies have claws that maintain the throat of an envelope at the inserting position open to receive a collation of insert material from a collation feeding mechanism adjacent the envelope inserting position. A microprocessor control means actuates the throat opening claw assemblies to release the upper edge of the envelope and substantially simultaneously actuates the envelope feeding means to move the envelope in a rearward direction momentarily, either after the collation is substantially fully inserted into the envelope or while it is still being inserted, to ensure that the collation is inserted sufficiently to bring the trailing edge of the collation beyond the crease line between the front panel of the envelope and the flap.

Motion control profile to improve reliability of inserter during

This invention provides utilizes a centering device located in the accumulation portion of mail production equipment to reduce jamming caused by the insertion of material into an open envelope. The apparatus of this invention is located in the accumulation area of production mail equipment before the inserter. The apparatus of this invention includes: two guides; a solenoid and a flexible wire cable. Two centering guides are actuated through a solenoid and move to a predetermined center position to align and deskew the accumulated enclosure contents (which may include printed and pre-printed folded sheets, business reply envelopes and other insert material). A flexible wire cable is used to provide highly efficient transfer of motion from the solenoid to the centering guides.

An envelope ejecting apparatus is disclosed for use in an inserting machine in which envelopes are fed successively in one direction along a feed path to a first location and then are moved incrementally in a reverse direction to an insert receiving position at which envelope throat opening devices open the throats of the envelopes so that insert material can be fed thereinto. The envelope ejecting apparatus is connected to the throat opening devices for operation therewith and also to the means for feeding the envelopes in the reverse direction, and there is a control means operatively interconnected between the envelope throat opening means and the envelope ejecting means for preventing the envelope ejecting means from ejecting the envelope until it is positioned at the insert receiving position and insert material has been inserted thereinto.

Ejection mechanism for envelope inserting machine

An apparatus for properly positioning envelopes in an envelope inserting machine for receiving insert material is disclosed in which the envelope positioning apparatus feeds a first envelope along a prescribed feed path to a predetermined location which is beyond the normal location at which the throat of the envelope can be opened so that the envelope can receive a package of insert material, and then feeds the envelope in a reverse direction until a throat opening device is effective to open the throat of the first envelope. A microprocessor, which controls the feeding of the envelope, is preset to feed the envelope to the first mentioned predetermined location, and has the capability to adjust the preset amount by which the envelope is fed by the amount that it is fed in the reverse direction so that all succeeding envelopes having the same shape and throat characteristics as the first envelope are fed direction to the location at which the throat of the first envelope is opened to receive the insert material.

Envelope positioning apparatus for inserting machine

An apparatus and method for centering and aligning sheets. The apparatus includes a D-roller assembly for cyclically engaging and transporting sheets and a centering and aligning mechanism for centering the lining sheets which is synchronized with the operation of the D-roller assembly so that the centering and aligning mechanism acts upon the sheets before the sheets are engaged by the D-roller assembly. The centering and aligning mechanism includes a pair of elements extending parallel to, and symmetrically from the center-line of, the path followed by the sheets and the elements cycle from first positions inward to second positions separated by approximately the width of the sheets so that sheets positioned between the elements are centered a aligned. Movement of the elements is synchronized with the D-roller assembly by a pair of complementary oppositely faced barrel cams mounted on a common shaft with the D-roller assembly. To center and align the sheets the D-roller assembly is rotated to cyclically open and close its nip and the elements are cyclically moved between the first positions and the second positions so that the elements reach the second positions while the nip is open, remain in the second positions until the nip closes, and return to the first position before the nip begins to close again. Sheets are fed into the D-roller assembly and between the elements during each cycle while the nip is open and the elements are approximately in the first positions.

A document registration apparatus for use in a document inserting station or a document queuing station is provided. The apparatus includes a document registration unit having a plurality of laterally-spaced registration stops for stopping motion of a document and registering a particular edge of a document to a particular direction in the apparatus. The registration unit also includes at least one non driver urge roller for moving the registered document away from the apparatus for further processing. The document registration apparatus also includes a jam access hinge for providing access to a jammed document.

Document registration apparatus

An adjustment device for adjusting a lever arm located inside a machine frame wherein the lever arm is pivotally mounted to the frame at a first location and is spring biased against a stop at a second location of the frame. The device comprises a resilient sleeve having a shank portion adapted to extend through an aperture in the frame to act as the stop, and a head portion of larger diameter then the diameter of the aperture in the frame. The shank portion has a threaded section and a non-threaded section, the non-threaded section having a length greater than the frame thickness at the aperture, wherein the lever arm pivots as a screw extending axially through the sleeve is turned in the threaded section.

Blind lever arm adjustment device

Apparatus for inserting one or more documents into a waiting envelope. The apparatus includes: a supporting frame; a device mounted in the frame for holding the envelope; a movable, endless belt rotatably mounted in the frame for transporting one or more documents into the waiting envelope; and a datum guide plate secured to the frame above the movable belt. The movable belt includes an upper reach which is biased toward the datum guide plate.

Envelope opening apparatus

Translatable registration apparatus in an envelope turning machine. The apparatus includes: a deck for transporting a plurality of envelopes from an upstream location to a downstream location; a translatable carriage mounted to the deck and adjustable for upstream and downstream movement to accommodate different size envelopes; a yoke pivotably mounted at its upstream end to the carriage, the yoke having a stopping finger projecting upwardly at its downstream end; a solenoid located beneath the finger and mounted to the carriage; and a device engaging the solenoid and the yoke for moving the finger up above the deck and down below the deck, wherein, when the solenoid raises the finger above the deck, the stopping finger is locked in a raised position with no pressure bearing on the solenoid.

Stopping device for envelope turner

Apparatus for turning an envelope, including: a housing; a transport deck secured to the housing for transporting an envelope from an upstream location to a downstream location, the deck including a device for moving the envelope; a vertically extending spindle located beneath the deck, the spindle being rotatable and reciprocable and having an upper end capable of extending above the transport deck; a device for raising and rotating the spindle; and a clamping arm assembly rotatably mounted to the housing situated above the transport deck, the clamping arm assembly having a device for applying a light, downward bias on the envelope against the upper end of the spindle, and a device for applying additional pressure to the envelope after the spindle is raised.
