A web folding machine for folding a continuously fed web into folded segments is disclosed. The machine includes a frame upon which the other components of the machine are mounted. A web supply provides continuous web material to these other components of the machine, with multiple feeds of the web material being processed in parallel relationship to one another. In one embodiment of the invention, web is pulled from a web supply by a pull roll station, which engages the web material to feed it at an approximately constant feed rate to a metering roll station. After proceeding through the metering roll station, the web reaches the folding station, where the web it is folded into a folded segment. In yet another embodiment of the invention, the web is first fed to a folding board that folds the web longitudinally. After the web is folded longitudinally by the folding board, it is fed to a pivoting marker web guide station that periodically pivots to vertically displace the web to create a marker. In a different embodiment of the invention, the folded segments are moved from the folding station to a packing station, which segregates the folded segments into accumulations and conveys the accumulations of folded segments away from the folding station.

A device for separating film sheets in a stack, particularly useful in X-ray installations, includes a threaded rotary screw member disposed within a magazine containing the stack of sheets for raising and lowering the sheet stack within the magazine and individually handling the uppermost sheet in the stack for transport to or from the magazine.

A device for transporting and buffering a flow of small articles, such as mail pieces, includes a conveyor belt that moves the articles onto a linearly displaceable carriage which delivers the articles into a buffer stack at a constant entrance angle regardless of buffer stack size. Articles in the buffer stack are supported and agitated by a plurality of rotating beater bars. Agitation causes skewed articles to level while the rotation of the beater bars transports the articles toward a moving edging belt that propels them into a feeder output. One of the plurality of beater bars includes screw thread sections for advancing the articles toward the feeder output.

An apparatus for stacking flat articles on-edge has a helical drive assembly with spaced-apart helical screws. The helical screws receive and hold the articles on-edge therebetween, and eject the articles towards a stack holding unit. The stack holding unit is configured to hold a stack of articles on-edge separately from the helical screws. The apparatus includes a conveyor that supports the lower edges of the articles during their transport to the stack holding unit. The stack holding unit has an article entry opening with a height that is smaller than a height of the articles to be stacked during operation, and the height of the article entry opening is preferably adjustable.

A device for aligning flat objects, in particular mail items, has a base face, a side wall, and at least one spindle thread, which is let into the base face. The spindle thread is embodied to transport flat objects lying on the base face in a conveyance direction, thereby pushing them against the side wall. The spindle thread has at least one aligning region. Each aligning region is subdivided respectively into a decompression segment and a compression segment. The pitch of the spindle thread increases along the conveyance direction in each decompression segment and decreases in each compression segment.

Disclosed is a device for conveying a stack of flat objects, in particular a stack of mail items, in a conveyance direction. The conveyor device comprises a base face, a side wall, which is perpendicular to the base face, a base face conveyor facility let into the base face and a side wall conveyor facility let into the side wall. The side wall is divided into two partial side walls. The rear partial side wall—viewed in the conveyance direction—is offset outward in a direction perpendicular to the conveyance direction in relation to the front partial side wall. The side wall conveyor facility is let into the rear partial side wall. The base face conveyor facility is embodied to exert a force on the objects, which moves the objects toward the side wall conveyor facility.

Methods and devices for folding a continuous web of material are provided. Systems can include a spiral folder assembly having first and second sets of rotatable spirals, a deflection means to guide the continuous web toward the first set of spirals and the second set of spirals, a beater assembly to urge the continuous web against the first set of spirals to form a first fold in the web against the second set of spirals to form a second fold in the web, and a conveyor assembly to receive and transport the folded continuous web as it exits the spiral folder assembly, the conveyor assembly providing a support between the first and second sets of spirals, the support modulating an amount of sag in the continuous web as the web is suspended between the first and second sets of spirals.

A high speed mail sorting machine which includes an improved screw conveyor in the magazine section and an improved pick off device for separating the individual envelopes from one another. The screw conveyor includes four driven rollers having spiral grooves for receiving the lower edges of the envelopes to convey them along the rollers. A pair of raised rollers with spiral grooves maintain the envelopes in a vertical orientation as they are conveyed along the lower rollers. The pick off device includes a conveyor belt and a relatively strong vacuum box which draws the leading envelope against the belt. An opposing vacuum box of lesser intensity draws any stuck envelopes away from the leading envelope to assure separation. The opposing vacuum box has a beveled surface which effects a staggered shingle arrangement of any extra envelopes adhering to the leading envelope.
