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.

A feeding mechanism for feeding a web of paper in a paper handling system includes a feeding nip assembly having a driven roller structured to be rotatably driven about a first axis, and an idler roller structured to rotate about a second axis substantially parallel to the first axis. In addition, the feeding nip assembly is structured to apply a force to the idler roller to push the idler roller toward the driven roller. The force is applied in a direction substantially perpendicular to the first axis and the second axis. The idler roller is also structured to pivot about a third axis substantially perpendicular to the first axis, the second axis, and the direction of the force.

In a machine for processing sheet material, an apparatus for centering and deskewing the sheet material being processed, comprises a deck; a pair of side guides adjustably located above the deck; adjustment limiting structure coupled to the side guides for limiting the distance adjustments can be made; linkage structure operatively coupled to the side guides and to the adjustment limiting structure for maintaining fixed center adjustments to the side guides, the linkage structure comprising at least three links, including a center link pivotally mounted to a center point of the deck and two end links, each of the end links coupled to one of the side guides; and friction structure coupled to each of the side guides for maintaining a position of the side guides after an adjustment is made.
摘要:
A buckle chute for folding a sheet of paper. The buckle chute includes: a first plate having a vertically extending slot; a second plate opposing the first plate and defining a paper path therewith; a paper stopping tab extending through the vertically extending slot; a paper inverting tab extending through the vertically extending slot and situated above the paper stopping tab, the inverting tab being pivotable between an operative position in the paper path and an inoperative position out of the paper path; and a lever operatively connected to the paper inverting tab and extending beyond the side edge of the first plate for pivoting the tab between the operative and inoperative positions.

In the enclosure inserting apparatus comprising structure for conveying an envelope along a flap unfolding path to an enclosure inserting location, structure for unfolding the flap of the envelope as the envelope is conveyed along the flap unfolding path to the enclosure inserting location, structure for holding the flap-unfolded envelope open at the enclosure inserting location, and structure for moving an enclosure along an enclosure feed path to the held-open envelope and inserting the enclosure into the held-open envelope, wherein the flap unfolding structure comprises structure for engaging the flap of an envelope moved therepast, and the flap unfolding path includes a gap having a width determined by a distance between the envelope conveying structure and the engaging structure, the improvement comprises a flapper blade adjustably mounted to the engaging structure for adjusting the width of the gap.
摘要:
An improved apparatus and method for accumulating sheets having a horizontal transport deck. Inserts are fed from an insert feeder positioned above the deck. Driven accumulator nip rollers are positioned to receive accumulations of sheets transported on the horizontal deck, and they are also positioned close enough to the insert feeder to receive inserts fed from the insert feeder. A recessed accumulation deck is positioned immediately downstream of the accumulator nip rollers. When a first sheet rests in the recessed accumulation deck, a subsequent second sheet will be placed on top of the first sheet when it enters the recessed deck. The process is controlled whereby insert sheets are released by the insert feeder prior to arrival of an accumulation on the deck. The released insert is driven by the accumulator nip rollers onto the recessed accumulator deck. Then when the accumulation arrives, it is deposited on top of the insert resting there.

Apparatus for turning an envelope. The apparatus includes: a pivotable feed deck for receiving an envelope; a device for stopping the envelope on the feed deck; a device for raising and lowering the downstream end of the feed deck; and a pivotable upper arm drive located above the feed deck. The drive is pivotable at its upstream end and includes a pair of feed rollers fixedly secured to the upstream end of the drive, a pair of exit rollers fixedly secured to the downstream end of the drive, and a pair of biased exit rollers secured to the drive adjacent and upstream of fixedly secured exit rollers.
摘要:
A fluid level detector comprises a tank including a sleeve portion extending vertically from a bottom section of the tank to a top section of the tank, and sensor device mounted to a circuit board connected at one end to monitoring device, with the circuit board being inserted into the sleeve. There is a circular float assembly with a center aperture. The circular float assembly includes a pair of magnets mounted in push-pull orientation at opposite sides of the aperture within the float assembly. The float assembly is slidably positioned over the sleeve whereby the float assembly moves up and down the sleeve as the water level changes in the tank, wherein the sensor device generate a signal representing detection of fluid level by the sensor device when the fluid level in the tank is substantially at the level of the sensor device.
