90 results about "Web feed" patented technology

On the World Wide Web, a web feed (or news feed) is a data format used for providing users with frequently updated content. Content distributors syndicate a web feed, thereby allowing users to subscribe a channel to it. Making a collection of web feeds accessible in one spot is known as aggregation, which is performed by a news aggregator. A web feed is also sometimes referred to as a syndicated feed.

Apparatus and methods usable in connection with dispensing flexible sheet material from a roll

A powered dispenser for dispensing individual sheet segments from a continuous roll of sheet material provided with spaced tear lines comprises a powered feed mechanism, a releasable, powered drive mechanism, a powered transfer mechanism, a pair of web sensing sensors, a capacitive sensing system providing automatic sensitivity adjustment, and control circuitry. A dual power supply system provides a mechanical lock-out functionality, and the control system is protected from electrostatic build-up on the surface of the feed roller. The web sensor, and an antenna plate of the capacitive sensing system, are provided on respective printed circuit boards mounted in overlying relation. Utilizing signals received from the pair of web sensors and the capacitive sensing system, the control circuitry senses the presence of a user to activate the powered drive mechanism, and prevents further dispensing of the sheet material until a previously dispensed segment is separated from the roll. The web sensors detection of a leading edge of the sheet material initiates a predetermined interval of sheet material advancement providing a proper placement of successive tear lines. Various approaches may be utilized to accommodate inadvertent sheet “tabbing” scenarios. The web sensors, together with the control circuitry, are also used to detect the depletion, or absence, of a working roll of sheet material, whereupon the control circuitry controls the powered transfer mechanism to automatically transfer the web feed supply from a depleted working roll to a reserve roll. The powered transfer mechanism may include a motor driven transfer bar, or provide motor driven release of a spring biased transfer bar. Another arrangement allows for ready release of a roll core, and drop of the same into an open dispenser cover for removal.

Motion control system and method for a high speed inserter input

InactiveUS20060156876A1Faster and accurate and reliable high speed cuttingImprove throughputFunction indicatorsPile receiversControl systemPaper document
A high speed input system for an inserter machine. The system controlling a guillotine cutter, a cutter transport, and an upstream web handler transport to increase throughput for mail production. The controller is programmed to control the high speed input module in accordance with a repeating cycle. The cycle time is determined as an amount of time between a first web feed request and an earliest possible time that a subsequent second web feed request can be acted upon. A cutter transport motion control profile initiates feeding of a document length of web after receiving the first feed request. The cutter motion control profile causes the cutter blade to begin descending when the cutter transport has moved the web a trigger distance, calculated such that the cutter blade will first make contact with the web immediately when the web has been halted by the cutter transport motion profile. A web handler transport profile moves the web the document length at velocities and accelerations less than the velocities and accelerations of the cutter transport. At the end of the cycle, the web handler transport causes the web to be transported at a nominal velocity selected to maintain an appropriate amount of the web loop in the web handler. Within the web handler a control loop expands and contracts as the downstream cutter transport stops and starts as the cutter blade cuts the web in each cycle.
