  • Patent number: 5904644
    Abstract: Apparatus and method for closing an envelope having a body portion and a flap, and a crease between the body portion and the flap. An open envelope is gripped and transported toward an abutment, which can be either a leaf spring or a slideable weight. The abutment is biased toward the envelope, but the force of the advancing envelope moves the abutment in a direction opposite the direction of bias, until the crease clears the transport structure that is moving the envelope. Once this happens, then the advance of the envelope stops and the bias of the abutment forces the envelope, crease first, between rollers that press the folded flap against the envelope. Any size envelope can be handled, because the abutment can move under the force of the envelope, any distance required to accommodate the size of the envelope.

  • Patent number: 4527378
    Abstract: The disclosure is directed to a semi-automatic mail insertion machine which assists an operator in placing materials into envelopes by presenting automatically unfolded and opened envelopes in rapid succession to the operator for manual placement of the materials therein. The machine includes a horizontal conveyor which, under operator control, incrementally advances the envelopes to be processed from one processing station to another in succession. An envelope stacker is positioned above the conveyor and a feed means feeds the envelopes to the conveyor prior to each advancement of the conveyor. The envelopes are conveyed to a first process station which automatically unfolds the pre-folded unsealed envelope flaps. The envelopes are then advanced to a second processing station which opens the envelopes and presents the envelopes to the operator in a manner which permits ready placement of materials into the envelopes.

  • Patent number: 4504260
    Abstract: Envelope blanks are scored and folded by pressing the flat blanks through a series of scoring and folding rolls. The rolls include vacuum rolls which invert the envelope blanks during the scoring operation. The blanks are scored laterally and as they pass over the outer surface of one of the vacuum rolls they are scored longitudinally. During the longitudinal scoring operation, the envelopes are curvilinear due to their being drawn down onto one of the vacuum rolls. After the longitudinal scoring operation, the blanks are inverted by being folded along the transverse score. The inverted, folded blanks are then moved along by a pair of cooperating vacuum rolls to a gumming station. After being gummed, the blanks are folded along their longitudinal scores with the folded flaps being secured in place by the gum.

  • Patent number: 4270909
    Abstract: A device and method for folding the main and secondary flaps of self-sealing envelopes into the inoperative condition. The envelopes (11) are fed, bottom edge leading, into a roller (20), the front panel of the envelope being in contact with the roller. The bottom edge lifts off the roller and the envelope is arrested and temporarily supported by abutment means (38,40,44) while the main flap (16) of the envelope is held to the roller by suction (22,24) and carried around the roller and thereby folded relative to the front panel of the envelope. In this position of the envelope, the secondary flap (18) slidably engages the surface of the roller and is then arrested by stop means (28) which carry the secondary flap (18) around and fold it relative to the back panel of the envelope.
