Method for binding books

Claim 1

A method of binding hard cover books, including: printing a plurality of signatures; folding said signatures; collating said printed signatures to position the folded-over edges of adjacent signatures in juxtaposition with one another to form a back bone and to place the pagination in seriatum; cutting of said back bone to separate the edges of each page of said signatures from one another to form a flat cut off back surface; applying flowable glue to said back surface and in between the edges of adjacent edges of said pages along said back surface; providing a paper cover of heavier stock than said signatures and of sufficient size to form opposite sides to cover the opposite sides and a back side to cover the back surface of said collated signatures; pressing said back side of said paper cover to said glue along said back surface; providing a hard cover of sufficient size to cover the opposite exteriors of said paper cover and to pass around the back side of said cover and of sufficient flexibility along the opposite sides of said back to form respective hinges therealong; and gluing the interior surfaces of the opposite sides of said hard cover to the exterior surfaces of the opposite sides of said paper cover and the back of said cover to cooperate therewith in forming a spine.

Claim 2

A method of binding hard cover books, including: printing a plurality of signatures; folding said signatures; collating said printed signatures to position the folded-over edges of adjacent signatures in juxtaposition with one another to form a back bone and to place the pagination in seriatum; cutting of said back bone to separate the edges of each page of said signatures from one another to form a flat cut off back surface; applying flowable glue to said back surface and in between the edges of adjacent edges of said pages along said back surface; providing a paper cover of heavier stock than said signatures and of sufficient size to form opposite sides to cover the opposite sides and a back side to cover the back surface of said collated signatures; pressing said back side of said paper cover to said glue along said back surface; providing a hard cover of sufficient size to cover the opposite exteriors of said paper cover and to pass around the back side of said cover and of sufficient flexibility along the opposite sides of said back to form respective hinges therealong; and gluing the interior surfaces of the opposite sides of said hard cover to the exterior surfaces of the opposite sides of said paper cover and the back of said cover to cooperate therewith in forming a spine.

Claim 3

A method of binding hard cover books, including: printing a plurality of signatures; folding said signatures to form a folded-over back edge; collating said printed signatures to position said folded-over edges in juxtaposition with one another to form a back bone and to place the pagination in seriatum; cutting off said back bone to separate the edges of each page of said signatures from one another to form a flat cut off back surface; applying flowable glue to said back surface; providing an inside paper cover having opposite sides of sufficient size to cover the opposite sides of said collated signatures and a back side to extend around said back surface; gluing the back side of said inside paper cover to said back surface; providing an outside paper cover of heavier stock than said signatures and having opposite sides of sufficient size to cover the opposite sides of said inside cover and a back side to cover the back surface of said collated signatures; applying glue to the exterior surface of the back side of said inside cover and to the exterior surface of the opposite sides thereof; providing a hard cover of sufficient size to cover the opposite exteriors of said paper cover and to pass around the back side of said cover and of sufficient flexibility along the opposite sides of said back to form respective hinges therealong; and gluing the interior surfaces of the opposite sides of said hard cover to the exterior surfaces of the opposite exterior sides of said outside cover and to the back side of said cover to cooperate therewith in forming a spine along such back side.

Claim 4

A method of binding hard cover books, including: printing a plurality of signatures; folding said signatures to form a folded-over back edge; collating said printed signatures to position said folded-over edges in juxtaposition with one another to form a back bone and to place the pagination in seriatum; cutting off said back bone to separate the edges of each page of said signatures from one another to form a flat cut off back surface; applying flowable glue to said back surface; providing an inside paper cover having opposite sides of sufficient size to cover the opposite sides of said collated signatures and a back side to extend around said back surface; gluing the back side of said inside paper cover to said back surface; providing an outside paper cover of heavier stock than said signatures and having opposite sides of sufficient size to cover the opposite sides of said inside cover and a back side to cover the back surface of said collated signatures; applying glue to the exterior surface of the back side of said inside cover and to the exterior surface of the opposite sides thereof; providing a hard cover of sufficient size to cover the opposite exteriors of said paper cover and to pass around the back side of said cover and of sufficient flexibility along the opposite sides of said back to form respective hinges therealong; and gluing the interior surfaces of the opposite sides of said hard cover to the exterior surfaces of the opposite exterior sides of said outside cover and to the back side of said cover to cooperate therewith in forming a spine along such back side.
