Abstract: A printing and binding apparatus (1) is disclosed which can print on demand, bind, and trim a perfect bound book. The apparatus includes one or more text page printers (110, 200) and a color cover printer (114). The text page printers print the text pages of a book and form the text pages into a book block (BB). The color cover printer (114) prints a cover for the book. The book block and the cover are delivered to a binding station at which the spine (S) of the book block is adhesively bound to the cover. The bound book is then delivered to a trimming station (TS) at which excess margins (are trimmed from the book. A method of printing and binding a perfect bound book on demand is also disclosed.

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.

Abstract: A perfect bound book construction is disclosed in which the book has a book block comprising a plurality of text pages, and a soft paper cover. The inner and outer faces of the cover are laminated with a plastic film so as to form a double laminated cover. The center portion of the inner lamination of the double laminated cover is conditioned or roughened, as by scarifying, so that an adhesive will adhere to the inner lamination and bind the spine of the book block to the double laminated cover. Apparatus for and a method of printing books on demand with such double laminated covers is also disclosed.

Abstract: A trimmer (1) is disclosed from trimming excess margins (M) along one, two or three edges of a perfect bound book (B) is disclosed. The trimmer has a shearing blade (15) movable in a shearing plane (SP) between an open and a closed position. The book is gripped by a book holder (35) proximate the spine (S) of the book and the book holder is vertically positioned such the shear blade will shear the book in a predetermined position along this first edge of the book. The book holder is then moved transversely with respect to the blade and the book is rotated 180° and the book holder is vertically positioned so that a predetermined amount of the margin along this second edge is trimmed from the book upon closing of the shear blade. The book is then moved transversely to a third position and the book is rotated 90° and the book holder is vertically positioned so that a predetermined amount of the margin along this third edge is trimmed from the book upon closing of the shear blade.

Abstract: A binder/trimmer is disclosed in which a book block is placed in a carriage, jogged to align the pages, and then transported to a milling station in which the spine of the book block is milled to roughen the spine, then to an adhesive application station at which a suitable adhesive is applied to the spine, and thence to a binding station at which the spine of the book is brought into engagement with the center portion of a cover and at which a binding clamp forces the cover against the outer faces of the book block proximate the spine, and then to a trimming station. At the trimming station, the book is deposited in a nest and is positioned relative to a trimming blade which is actuated to trim a first edge of the book to a predetermined dimension. The book is then rotated to trim second and third edges thus resulting in a perfect bound book accurately trimmed to a predetermined size. A method of binding and trimming a perfect bound book is also disclosed.

Abstract: A binder/trimmer is disclosed in which a book block is placed in a carriage, jogged to align the pages, and then transported to a milling station in which the spine of the book block is milled to roughen the spine, then to an adhesive application station at which a suitable adhesive is applied to the spine, and thence to a binding station at which the spine of the book is brought into engagement with the center portion of a cover and at which a binding clamp forces the cover against the outer faces of the book block proximate the spine, and then to a trimming station. At the trimming station, the book is deposited in a nest and is positioned relative to a trimming blade which is actuated to trim a first edge of the book to a predetermined dimension. The book is then rotated to trim second and third edges thus resulting in a perfect bound book accurately trimmed to a predetermined size.

Abstract: A system for the perfect binding of a book block (14) within a soft paper cover is disclosed in which the center portion (18) of the cover is sized relative to the thickness of the book to be bound. An activatable adhesive is applied to the inner surface of the center portion of the cover. The book block is inserted into the cover such that the spine (S) of the book block is generally in register with the adhesive. The cover is forcibly compressed onto the book block by pressing members (60a, 60b).

Abstract: A skid-control traction-control system is provided for a motor vehicle including at least two driven wheels connected by a differential mechanism, characterized by the provision of a skid-control solenoid valve operable--when the vehicle is decelerating and either driven wheel has a rotational deceleration which differs from an estimated predetermined amount--for automatically deactivating the brakes associated with both driven wheels, in combination with a system operable--when the vehicle is accelerating and one driven wheel has a rotational velocity which differs from the other by a predetermined amount--for automatically braking only the faster driven wheel, thereby causing torque to be transferred to the slower wheel via the differential mechanism.

Abstract: A wheel speed sensor including a rotor and a stator with the stator being coaxially disposed within an elastomeric member for incremental axial movement upon engagement with the rotor. The stator includes a pole member, a bobbin and coil assembly, and a magnet which are axially aligned to provide an elongated stator structure which is coaxially disposed in a tubular member which guides the incremental axial movement of the stator. A method for prestressing the elastomeric member for setting the required applied force for axially moving the stator.
