摘要:
An apparatus including a belt support system having a first belt support roller and a system for automatically moving the first belt support roller. The belt support system partially wraps a continuous belt on a belt drive roller. The belt support system includes the first belt support roller at an upstream side of the belt drive roller and a second belt support roller at a downstream side. The system for moving the first belt support roller moves the first roller from a first location relative to the belt drive roller to a second different location, based upon a predetermined load of the belt on the first belt support roller to thereby reduce an amount of wrap of the belt on the belt drive roller and reduce a length of the belt located proximate to the belt drive roller between the first and second belt support rollers.

A vacuum deck for a mailpiece insertion module including a plurality of friction drive belts, a support plate slideably supporting the drive belts, a repositionable backstop assembly disposed along the feed path of the envelope for arresting the motion of the envelope when disposed in a first position and permitting the conveyance along the feed path when disposed in a second position, a means for developing a pressure differential across the envelope for urging the envelope into frictional engagement with the friction drive belts, and a breaker plate disposed over and across an upstream portion of the friction drive belts to reduce friction drive forces developed along an upstream end portion of the envelope. In another embodiment of the invention, the pressure differential means is bifurcated such that the pressure differential developed across the breaker plate is lower than the pressure differential developed along the support plate and downstream of the breaker plate.

A paper cutting system includes a cutting assembly, a transport moving a web through the cutting assembly, a vacuum plenum utilizing a vacuum source to control the web moving through the cutting assembly, an air source providing purge air to the cutting assembly for removal of debris, and a heat exchanger normalizing a temperature of the purge air with respect to a temperature of ambient air prior to the purge air reaching the cutting assembly. The heat exchanger may be operated using the vacuum source.
摘要:
An apparatus for inverting the spatial orientation of sheet material from a desired input to a desired output orientation. The apparatus includes a cage assembly, a torque drive mechanism operative to rotate the cage assembly about a rotational axis and a sheet conveyance mechanism mounting to the cage assembly for conveying sheet material along the rotational axis of the cage assembly. The torque drive mechanism is adapted to assume input and output positions about the rotational axis wherein each position corresponds to the desired input and output orientations of the sheet material. The sheet conveyance mechanism is, further, adapted to: (i) receive sheet material when the cage assembly is in the input position, (ii) eject sheet material when the cage assembly is in the output position and (iii) retard the movement of the sheet material in response to rotation of the cage assembly by the torque drive mechanism.
摘要:
A method for creating mailpieces from a single web of printed material. The web of printed material includes printed matter to be used on envelopes, and other printed matter to be used on mail content to be included in the envelopes. The content pages are rectangular in shape and may be oriented relative to the envelope sheets in a number of different configurations. In some configurations, two sets of content pages and/or envelope sheets can be printed across the width of the web. The method starts with cutting consecutive sections of the web into separated sheets. Some of the separated sheets are envelope sheets including envelope printed matter, and some of the sheets are mail content sheets including mail content printed matter. The method includes cutting variable sized sheets depending on whether a sheet is a mail content sheet, or an envelope sheet. The method further includes cutting variable sized envelope sheets depending on the size of the mailpieces. In a preferred embodiment, the web includes business return envelopes (BREs). The BRE sheets are transported to an envelope creation path and in the envelope creation path where the sheets are formed into envelopes. The envelope creation path is then merged back with a content processing path whereby finished BRE's are stacked with their respective accumulations of folded content sheets to form a complete content stack. BRE's are then enclosed with the content sheets by the enclosing envelope sheets.

An inserter input system including a web feeder providing a web of printed material to be split by a web slitting knife along the web's direction of travel. The split web is then cut transverse to the direction of travel by a rotary cutter operating at a first velocity, resulting in side-by-side individual sheets. Downstream of the rotary cutter, a right angle turn mechanism receives each of the side-by-side sheets and reorients them by ninety degrees. Further the right angle turn reorients the sheets into a serial shingled arrangement. A high speed separation nip pulls individual shingled sheets out from the shingled arrangement. The speed of the separation nip is such that a predetermined gap between the previously shingled sheets is formed. In a further preferred embodiment of the present invention, the speed of the rotary cutter and right angle turn mechanism are controlled to adjust a quantity of sheets that would be generated from displacement traveled due to inertia during a deceleration of the system to a stop.

A module in an envelope insertion station for transporting an envelope to an enclosure material insertion location, which uses endless belts to move the envelope until it is stopped by rotatable stops. A fixedly-mounted vacuum module having vacuum ports provides a suction force to the envelope urging the trailing edge of the envelope to press against the belts and provides the normal force required to move an envelope downstream as it enters the insertion deck without slippage against the translating endless belts. Additionally, a second vacuum module having vacuum ports provides suction force urging the leading edge of the envelope to press against the belts and provides the normal force required to prohibit the leading edge of the envelope from buckling during impact with the rotatable stops. The second vacuum module is removably mounted and mechanically linked to the rotatable stops so they can be repositioned together to accommodate different-sized envelopes.

A dry cleaning system for removing dust and lint on the fly from blanket cylinders in offset printing presses. The cleaning system includes a relatively small brush mounted for rotation about an axis substantially perpendicular to the rotational axis of the blanket cylinder. In operation, the brush can be reciprocally moved across the surface of the blanket cylinder and selectively moved into and out of contact with the blanket cylinder. The contact pressure of the brush is pneumatically controlled to maintain a predetermined, set pressure and the brush automatically retracts should the pressure source fail. The system can be operated to clean the entire width of the blanket cylinder or only the portion of it actually being used to print. A vacuum pickup is included with its separately mounted housing and the entire cleaning system is carried on a unitary support structure that is removably secured at its ends for quick and easy installation and removal.
