Abstract
A set of sheets delivered seriatim from a copier/duplicator or other source are advanced along a sheet path leading from an input station to an assembly station where a booklet is formed. As a sheet is moved along the path a line of adhesive is applied to one surface of the sheet adjacent to one side edge of the sheet. In the assembly station the sheets are jogged to align the sheets of the set and then pressure is applied to the sheets over the line of adhesive. When the entire set has been bound together into a booklet, the booklet is removed from the assembly station and delivered to an output station, such as a tote tray.
Claims17
A method for producing collated sets of copy sheets from a set of document sheets and for adhesively binding each set of copy sheets into a booklet, the method comprising the steps of:
- circulating a set of document sheets arranged in page sequential order seriatim a plurality of times to a document imaging station;
- copying each document sheet once each time it is circulated to the imaging station, thereby producing a stream of copy sheets to form sets having a page sequence corresponding to the set of document sheets;
- advancing the stream of copy sheets initially in a first direction with the trailing edge of each copy sheet comprising the edge that is to be bound to other sheets and then advancing the stream of sheets in a second direction with the sheet edge to be bound to other sheets being located along one side edge thereof;
- applying a stripe of liquid adhesive to copy sheets and stacking each set of copy sheets in the same order as the set of document sheets with adhesive being applied so that there is adhesive between adjacent copy sheets in a set of copy sheets, the adhesive being applied to such one side edge of the copy sheets while the sheets are advanced in the second direction;
- and
- applying pressure to each set of stacked copy sheets in the area where adhesive is located between the sheets, thereby to form bound booklets of copy sheets corresponding in order to the order of sheets in the document set.
A method for binding a set of sheets together adjacent to one edge of the sheet to form a bound booklet;
- the method comprising the steps of:
- feeding sheets seriatim in a first direction into an input station;
- aligning each sheet in the input station;
- advancing the sheets seriatim in a second direction along a sheet path leading from the input station to an assembly station where the booklet is formed, the second direction being substantially perpendicular to the first direction;
- inverting each sheet before the sheet reaches the assembly station;
- applying a continuous stripe of liquid adhesive to the second sheet and each subsequent sheet of the set as the sheets are advanced along the sheet path in the second direction and before the sheets are inverted, the adhesive being applied to the upper surface of each sheet adjacent and parallel to the edge of the sheet that is the trailing edge as the sheet moves in the first direction;
- aligning the sheets of the set in a stack in the assembly station with the first sheet advanced along the path being at the bottom of the stack and with subsequent sheets advanced along the path being above the first sheet and in the same order as the sheets were advanced along the path;
- and
- applying pressure to sheets in the assembly station above the stripe of adhesive on the sheets to facilitate binding of the sheets together, thereby to form a bound booklet.
A method for binding together a plurality of sheets, the method comprising the steps of:
- moving a plurality of sheets seriatim along a path and past a nozzle;
- applying a stripe of liquid adhesive to a sheet as it moves past the nozzle, the adhesive applying step comprising initiating the flow of adhesive from the nozzle and then driving a sheet past the nozzle so that a continuous strip of adhesive is applied along the sheet from one edge of the sheet to another edge of the sheet and in a direction parallel to the direction of travel to the sheet;
- and
- stacking a plurality of sheets having adhesive thereon so that the adhesive is between adjacent sheets.
