Abstract: A cutting device of packing apparatus includes at least three cutting blades arranged around the packing material expanding cylinder in a substantially equally-spaced manner. The cutting blades are rotatable about their own rotational axes in a synchronous manner for cutting off the continuous packing material along a circumferential slit formed on the cylinder. This simplifies the overall structure by eliminating a mechanism to move the blades around the cylinder. By using a number of blades rotatable in synchronization with each other, the time period for a single blade in contact engagement with the packing material to be cut off is substantially reduced and the efficiency of the cutting operation is enhanced. Due to the enhanced efficiency, the delay of time in the alternation of the feeding operation and cutting operation is lowered down.

Abstract: A media buffer capable of buffering two lengths of media, is fed a first length of media from an imagesetter at a first speed, and releases the media to a processor at a second speed. An input media sensor senses the media entering the buffer. Drive rollers take up the leading edge of the media at the imagesetter speed. Shortly thereafter a signal from an output media sensor located between the drive rollers and the processor, opens an input door to an input bin and stops the drive rollers. The incoming media continues to be fed by the imagesetter forming a first slack loop within the input bin. The imagesetter signals the buffer that the media has been cut, thereby actuating drive rollers to advance the media at the processor speed to a pair of rollers in the processor. A signal from the processor sensor opens an output door to an output bin. The drive rollers increase speed to transport the first piece of media from the input bin to the output bin thereby forming a second slack loop.
