  • Publication number: 20190337783
    Abstract: A fork lift apparatus is mounted on a truck for picking up a load, placing the load in a traveling position on the truck, and for unloading the load. The apparatus comprises a lift frame, a shaft, a pair of spaced arms secured to the shaft, a cross member spanning between the distal ends of the arms distal and carrying the forks. The cross member is rotatable relative to the support arms. A pair of drive hydraulic cylinders rotates the shaft and thus moves the arms and the load between a loading/unloading position in which the load may be placed on the forks and the traveling position so that the load may be transported by the truck. A self-leveling system is provided for maintaining the load in a substantially level position as it moves between its loading/unloading and traveling positions.

  • Patent number: 8739730
    Abstract: Apparatus is disclosed for controlling the depth of a layer of a layer of adhesive on a peripheral surface of a rotary member (e.g., a wheel) for the application of the adhesive to an object. The apparatus comprises a heated reservoir containing a supply of hot melt adhesive maintained within a desired temperature range, where the rotary member is partially immersed in the adhesive and is rotated by a motor such that the as the rotary member is rotated up out of the peripheral surface of the rotary member has the layer of adhesive thereon. A computer controls system controls the motor such that the speed of the rotary member may be increased or decreased so as to vary the depth of the adhesive on the peripheral surface of the rotary member.

  • Patent number: 8556563
    Abstract: 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.

  • Publication number: 20110159170
    Abstract: 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.

  • Publication number: 20110121508
    Abstract: 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.

  • Publication number: 20110110747
    Abstract: 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.

  • Publication number: 20110044786
    Abstract: 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.

  • Publication number: 20090220289
    Abstract: 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.
