Abstract
A book spine coating nozzle is provided with adjustable side sealing jaws for adjusting the nozzle width for different book thicknesses and having distinct, separate side glue outlets for depositing glue on the book sides. Glue flow control valves are disposed between the nozzle and outlets so the glue deposited on the book sides can be selectively and independently cut off or controlled.
Claims12
Apparatus for applying glue to the spine and side edges of a book including:
- a die defining a slot for exuding glue onto a book spine at an adhesive station;
- and
- two movable sealing jaws for applying glue to the sides of a book through respective outlet ports at said station;
- said sealing jaws each including:
- a sealing means having a glue passageway therein for receiving glue form said slot and for transporting glue to said outlet port, and
- glue flow control means operably disposed within said passageway for controlling the flow of glue from said die slot to said outlet port wherein said sealing means has an elongated recess extending along said slot and said glue passageway communicates within an inboard end of said recess for receiving glue from said slot and recess when said slot exudes glue for coating said book spine.
Apparatus for applying glue to the spines and sides of book and comprising:
- an extrusion slot for applying glue to the spines of books, said slot having an elongated glue outlet;
- and
- two movable sealing jaws disposed adjacent said outlet and movable toward and away from each other;
- said sealing jaws each including:
- a glue outlet port for applying glue to a side of said books,
- a sealing means for sealing off a portion of said slot and having a recess extending in the same direction of the extrusion slot;
- a glue passageway extending between said recess in said sealing means and said glue outlet port, and
- glue flow control means disposed in said glue passageway.
Apparatus for applying glue to the spine of a book and to the sides of a book at a single station comprising:
- a glue manifold;
- a glue flow control valve in said manifold;
- a die means defining an elongated glue outlet from which glue is applied to said spine;
- a first glue passageway operably connecting said flow control valve to said slot;
- two opposed, movable, sealing jaws disposed over said slot and each having a sealing block with a groove therein extending over and along a portion of said slot;
- a glue outlet in each said jaw opening toward the opposite jaw for depositing glue on the sides of a book;
- a second glue passageway extending from said groove in each said sealing block to said glue outlet in said jaw;
- and
- a second glue flow control valve means in each said second glue passageway for controlling glue applied to said book sides independent of glue applied to said spine;
- and
- means for moving said jaws toward and away from each other over said slot for accommodating books of varying widths therebetween while retaining the capacity to selectively apply glue to the book sides.
