| 20090220289 | HIGH SPEED DUPLEX PRINTER - Apparatus and a method is disclosed for duplex printing of a document or a book block in which two printers operating in a simplex printing mode are used on both faces of a plurality of sheets forming a document or book block. The first printer prints an image on a first side or face of a sheet, where a number of sheets are stored in an queue between the first and second printers such that as sheets are printed by the first printer, they are delivered in sequence to the queue, where sheets are fed from the queue to the second printer without the first printer having to delay printing until the second printer is ready for the next sheet, and where the second printer may have a sheet delivered to it without the second printer having to await for the first printer to print a sheet thereby to allow both the first and the second printers to print at substantially their maximum simplex printing speeds. | 09-03-2009 |

| 20110044786 | APPARATUS FOR AND METHOD OF CLAMPING AND TRIMMING A PERFECT BOUND BOOK - Apparatus for trimming perfect bound books is disclosed including a clamping assembly and a shearing assembly, preferably powered by electric motors. The clamping assembly includes a fixed anvil and a clamp member movable along a clamp track toward and away from the anvil. The shear assembly includes a shear blade movable along a shear track toward and away from the anvil. Load members are mounted on the clamp track and on the shear track. The clamp assembly and the shear assembly each has an electric motor driving a linear actuator (e.g., a drive screw) which is operatively coupled to its respective load member. A spring or a pair of springs is interposed between the clamp load member and the clamp member and another spring or a pair of springs is interposed between the shear blade and the shear load member. Thus, as the clamp member engages the book and as the shear blade shears through the book and engages the anvil, further movement of the clamp member and the shear blade is prevented. Continued operation of the motors causes these springs to compress and to thus result in differential movement (lost motion) between the clamp member and the clamp load member and between the shear blade and the shear load member. Operation of the motors is terminated upon this differential motion of a predetermined magnitude being sensed. | 02-24-2011 |
| 20110110747 | APPARATUS FOR AND METHOD OF TRIMMING OF PERFECT BOUND BOOKS - Apparatus for and a method of determining and correcting the position and angularity of an edge of a book to be trimmed relative to a shearing plane is disclosed. The book is movable toward and away from the shearing plane and is rotatable about a rotary axis. A pair of spaced sensors generate an output signal indicative of the edge being proximate each the sensor so that upon each sensor generating its signal at substantially the same time thus indicating that the edge is substantially parallel to the shearing plane and so that if one sensors senses the edge before the other thus indicating that the edge is oriented at an angle relative to the shearing plane. A computer control system corrects the angle and vertically positions the edge so that a predetermined trim line for that edge is substantially in register with the shearing plane. | 05-12-2011 |
| 20110121508 | AUXILIARY FEED CONVEYOR - Apparatus is disclosed for feeding sheets of paper printed by a printer to a sheet processing device, such as a print on demand (POD) book publishing system. The printer has a sheet discharge through which each sheet printed by the printer is discharged or ejected one sheet at a time. The printer heats the sheets to an elevated temperature as the sheets are printed, and the sheets printed by the printer and discharged from the printer carry a static electricity charge. The sheet processing device has a sheet infeed located at a location (height) different from the printer sheet discharge. The apparatus has a sheet conveyor that has an inlet, an outlet, and a conveyor path between the conveyor inlet and the conveyor outlet for conveying the sheets from the printer sheet discharge to the sheet processing device sheet infeed. The sheets are accumulated in a stack within the sheet processing device. The apparatus has at least one fan that blows air on each the sheet as the sheet is conveyed along the conveyor path so as to at least partially cool the sheet, and the apparatus has a static electricity eliminator located along the conveyor path for at least partially eliminating the static electricity from the sheets as they are conveyed from the printer to the sheet processing device such that as the sheets are accumulated in the stack they are sufficiently cooled and have sufficient static electricity removed therefrom so that the sheets may be uniformly stacked one on the other in the stack. | 05-26-2011 |
| 20110150604 | REPLACEABLE SHEAR BLADE FOR BOOK TRIMMING APPARATUS AND METHOD OF CHANGING SUCH BLADE - A replaceable shear blade for a book trimming apparatus, the latter comprising a shear carriage having the replaceable shear blade mounted thereon. The shear blade has a sharp cutting edge for shearing a book between an anvil and the cutting edge. The shear blade is removably mounted with respect to the shear carriage for replacement of the shear blade, where the shear blade is removably secured relative to the shear carriage by a plurality of fasteners accessible from above. A removable sheath encloses the cutting edge. At least one removable handle is secured to the shear blade so that the shear blade and the sheath may be handled as a unit, with this handle being grippable from above for installation of the shear blade on the shear carriage, and with the handle and the sheath being removable from the shear blade upon installation of the shear blade on the shear carriage. A method of installation and removal of the shear blade is also disclosed. | 06-23-2011 |
| 20110159170 | APPARATUS FOR AND A METHOD OF DETERMINING CONDITION OF HOT MELT ADHESIVE FOR BINDING OF A PERFECT BOUND BOOK - Apparatus is disclosed for monitoring and signaling when a hot melt adhesive contained in a heated adhesive reservoir should be changed. A wheel is at least partially immersed in the adhesive in the reservoir and is rotated by a motor and a computer controls system controls the operation of the motor. From time to time, the computer control system operates the motor and compares the running current supplied to the motor at which the motor stalls to a predetermined stall running current corresponding to a predetermined viscosity level of the adhesive at which the adhesive exhibits a minimum level of binding characteristics and thus generates a signal to change the adhesive. A method of determining when the adhesive should be changed is also disclosed. | 06-30-2011 |
| 20110188972 | ADHESIVE APPLICATOR FOR PERFECT BOUND BOOKS AND METHOD OF APPLYING ADHESIVE - An adhesive applicator is disclosed for the application of a hot melt adhesive to the spine of a book block so as to adhesively bind the book block to its respective cover so as to form a perfect bound book. The applicator has a heated head in which a small quantity of a hot melt adhesive sufficient to bind at least one book block to its cover is quickly heated to a temperature such that it may be applied to the spine. The head is brought into operative engagement with the spine and is moved with respect to the spine so that the melted adhesive forced (dispensed) out of the head onto the spine. This applicator is particularly well suited for use with print on demand book printing and binding apparatus. A method of applying the adhesive to the spine of a book block is also disclosed. | 08-04-2011 |
| 20110194915 | ULTRASONIC BOOK TRIMMING APPARATUS AND METHOD - Apparatus for trimming a perfect bound book is disclosed having a platen for supporting a portion of the book as it is trimmed. A clamp holds the book against the platen, and a blade is provided having a cutting edge with the blade being movable toward and away from the book platen between a retracted position and an operable position in which the cutting edge is in operative engagement with the book. An ultrasonic (or other vibratory) member carries the blade, and the ultrasonic member is rendered resonant so that the cutting edge trims the book along the side of the book. A method of trimming a book using a vibratory blade is also disclosed. | 08-11-2011 |
