Abstract: The present invention provides a sorter preferably for an inserting system for sorting mailpieces into one of at least two sorting bins, the sorter having a transport device for conveying the mailpieces along a transport path. Each sorting bin includes a bending mechanism for bending the tail edge portion of a mailpiece and a final stacking roller for unbending the tail edge portion of the mailpiece such that the tail edge portion of the mailpiece is diverted into the sorting bin and away from the transport device without the occurrence of jamming of the mailpiece in the entry portion of the sorting bin.

Abstract: A buckle chute folder for folding one or more sheets of paper, including a buckle chute and a pair of folding rollers situated downstream of the buckle chute. Each of the folding rollers has a plurality of circumferential grooves extending perpendicular to the axis of the roller, and the grooves of one roller are offset with respect to the grooves of the other roller.

Abstract: For use in combination with a machine for feeding a web of paper in a downstream path of travel, there is provided apparatus for folding an unfolded web of paper along its longitudinally-extending weakened fold line. The apparatus comprises: a frame; web drag structure including a drag member which longitudinally extends across the path of travel of the unfolded web for frictional engagement by the web; a lower roller which is rotatably attached to the frame below the level of the drag member so as to extend transverse to the drag member and at an angle of approximately 95.degree.

Abstract: For use in combination with a machine for feeding a web of paper in a downstream path of travel, there is provided apparatus for folding an unfolded web of paper along its longitudinally-extending weakened fold line. The apparatus comprises a frame; a drag member attached to the frame so as to extend in frictional engagement with the unfolded web; a pair of parallel spaced rollers which are attached to the frame below the level of the drag member so as to extend at right angles to the drag member, such that an unfolded web may extend downwardly in its path of travel from said drag member to said upper roller and be folded between them and such that the folded web may threadably extend between the upper and lower rollers; and an output roller attached to the frame so as to extend parallel to said upper and lower rollers, such that the folded web may extend in its path of travel from beneath the lower roller to the output roller and then from beneath the output roller to the machine.

Abstract: A process and apparatus are provided for controlling a document inserting machine having a plurality of operating stations therein, one of which includes a high speed feeder for feeding documents bearing control function indicia thereon. The process involves detecting the leading edge of the document and generating time signals in accordance with the speed of the document through the feeder. The control function indicia are scanned for generating control function data bits therefrom which are stored and recycled on the occurrence of a first data bit, thereby converting the time measurement to a distance measurement which provides a means for producing accurate distance measurements between the occurrence of a first data bit and subsequent data bits based on the control function indicia on the document.
