Abstract: In apparatus for manufacturing and packaging bound books a turnover device is provided for turning over alternate books fed by a conveyor from a building-in machine and leading to a stacking device where such books are accumulated in stacks and delivered for packaging. The turnover device lifts alternate books from the consecutive line of books on an in-feed conveyor, turns the lifted books 180.degree., and replaces them in the spaces left vacant when the books were lifted. The conveyor system then transports these books positioned in alternate orientation, such that when they are stacked, their spines or backbones are on alternate sides of the stack which renders each stack less high, more stable and compact and easier to handle in subsequent packaging and shipping operations. The turnover device comprises a pair of continuous belts about rotating drums where each belt is twisted through 180.degree.
Abstract: A method for bookbinding on a continuously-moving, constant-speed conveyer belt operation with the case or back-strip being centrally located on the axis of motion. As the case is formed between opposing rotary irons, glue or paste is then applied to the upper insides of both sides of the case. A book block is next dropped on one side of the case, the book block is aligned to register with the case; and the other side of the case is folded over to fasten to the upper side of the book block to form the book and prepare it for pressing and crimping of the building-in operation, without any interruption of the motion of the book along the conveyer system.
Abstract: A flyleaf heat sealer for adhering a flyleaf having its inner surface pre-coated with hot melt or heat sensitive adhesive to the exposed outer surfaces of the end sheets of a book block insert, includes means for engaging and transporting a book block insert and the flyleaf folded therearound, means for directing a flow of air heated to a temperature adequate to melt the adhesive against and impinging upon the outer surfaces of the flyleaf, and means for pressing and cooling the flyleaf and book insert between them and removing heat from the flyleaf and book block, and thus curing and hardening the adhesive.
Abstract: A book making machine comprising casing-in instrumentalities and, optionally, building-in instrumentalities arranged so that the operations required to wrap a book with a cover are effected rectilinearly in succession comprising a cover feeder for delivering covers, one at a time, to a conveyor for movement along a predetermined path and, in succession, a heater for heating the covers, an embosser for embossing the covers to form fold lines, an adhesive-applying device for applying adhesive to the covers, a book feeder for depositing book inserts on the covers, registering devices for registering the inserts with the covers, wrapping devices for wrapping the covers about the inserts, pressure-applying devices for applying pressure to the wrapped inserts and forming devices for forming hinges in the cover panels at the back of the book.
Abstract: A method for binding a book wherein the backbone of printed and folded signatures receives a heat activated glue. A short reinforcing cover whose inner surface is also covered with a heat activated glue is applied to the backbone. The outer portions of the short cover are then bonded to the outer pages of the signatures, under sufficient heat and pressure to form a strong bond. A hard cover of suitable size and shape is then glued to the outside of the short cover and the signatures.
