Abstract

Abstract Separate leaves to be bound together are arranged to provide a book body, the body being supported and the leaves relatively displaced to round the back of the body and to produce a corresponding concave shaping along the front of the body. Adhesive is then applied to the rounded back so as adhesively to secure the separate leaves of the body together. Longitudinal string elements may be secured along opposite sides of the body adjacent to the back to form shoulders which, upon completion of the binding operation, cooperate in retaining the body firmly within a case of the binding.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 127 words
A method of book binding comprising the steps of arranging separate leaves in a body of book form for binding, supporting said body of leaves and relatively displacing the leaves so as to round the back of the body aNd to produce a corresponding concave shaping along the front of the body, arranging longitudinal elements along opposite sides of the book body adjacent the back thereof and adhesively securing said longitudinal elements in position to form shoulders at the opposite sides of the back of the body so that, when a case is applied to the book body, the shoulders co-operate in retaining the body in the case, and applying adhesive to the rounded back so as adhesively to secure together the separate leaves of the body.
Claim 2
Independent Claim 127 words
A method of book binding comprising the steps of arranging separate leaves in a body of book form for binding, supporting said body of leaves and relatively displacing the leaves so as to round the back of the body aNd to produce a corresponding concave shaping along the front of the body, arranging longitudinal elements along opposite sides of the book body adjacent the back thereof and adhesively securing said longitudinal elements in position to form shoulders at the opposite sides of the back of the body so that, when a case is applied to the book body, the shoulders co-operate in retaining the body in the case, and applying adhesive to the rounded back so as adhesively to secure together the separate leaves of the body.
Claim 3
Dependent Claim 31 words
A method of book binding as claimed in claim 1, wherein said longitudinal elements are secured in position by adhesive during the securing together of the leaves of the book body.
Claim 4
Dependent Claim 37 words
A method as claimed in claim 2, wherein during the formation of the book body, the leaves are gathered and clamped together, then trimmed along the edges thereof to provide a book body of substantially parallelepipedic form.
Claim 5
Dependent Claim 57 words
A method as claimed in claim 3, wherein following the trimming of the book body and before the rounding of the front and back edges thereof, the leaves are passed through a sheet displacement device thereby to displace the leaves to overcome any tendency of the leaves to adhere together as a result of the trimming operation.
Claim 6
Dependent Claim 54 words
A method as claimed in claim 3, wherein for the rounding of the back of the book body, the leaves are displaced relatively to one another by a jogging of the leaves to cause the back edges of the leaves to conform to the curvature of a concave face formed in a shaping member.
Claim 7
Dependent Claim 31 words
A method as claimed in claim 5, wherein the leaves are adhesively secured together by applying to the rounded back edge of the book body, a support which carries the adhesive.
Claim 8
Dependent Claim 45 words
A method as claimed in claim 6, wherein the adhesive comprises a hot melt adhesive and wherein the adhesive is activated by the heating of hot plate members upon which the shaped book body rests during the application of the adhesive to the book body.
Claim 9
Dependent Claim 95 words
A book binding machine comprising means for supporting a book of separate leaves to be bound together, means for relatively displacing the separate leaves so as to round the back of the book and to produce a corresponding concave shape along the front of the book, means for arranging along opposite sides of the book body longitudinal elements which extend adjacent the back and which are arranged to form shoulders adapted to co-operate in retaining the book body within a case, and means for applying adhesive to the rounded back to secure the leaves together.
Claim 10
Dependent Claim 95 words
A book binding machine comprising means for supporting a book of separate leaves to be bound together, means for relatively displacing the separate leaves so as to round the back of the book and to produce a corresponding concave shape along the front of the book, means for arranging along opposite sides of the book body longitudinal elements which extend adjacent the back and which are arranged to form shoulders adapted to co-operate in retaining the book body within a case, and means for applying adhesive to the rounded back to secure the leaves together.
Claim 11
Dependent Claim 57 words
A book binding machine as claimed in claim 8, including means for trimming the edges of the leaves to form a book body of substantially parallelepipedal form, and a device for relatively displacing the leaves in such a manner as to overcome any tendency of the leaves to adhere together as a result of the trimming operation.
Claim 12
Dependent Claim 77 words
A book binding machine as claimed in claim 8, wherein the means for relatively displacing the separate leaves for rounding the back and front edges of the book body, comprises a shaping member formed with a curved shaping face conforming to the curvature required in said back and front edges, and means for jogging the leaves to cause the back edges thereof to engage and take up a position corresponding to the curvature of said shaping face.
Claim 13
Dependent Claim 58 words
A book binding machine as claimed in claim 10, wherein the shaping member comprises a hot plate having two relatively movable sections, means for heating said hot plate sections, a clamping device for holding the leaves above the hot plate during a shaping operation, and mechanism for raising and lowering the hot plate relatively to the clamping device.
Claim 14
Dependent Claim 116 words
A book binding machine as claimed in claim 11, including a support plate for the hot plate sections, said support plate being formed with a profiled part corresponding to the curved shaping face of the shaping member, mechanism for moving the hot plate sections laterally outwardly so that following the shaping of the back of a book body and the application of adhesive thereto, the hot plate sections can be moved into laterally outer positions to permit the back of the book body to be engaged in the profiled part of the support plate, and the hot plate sections can then be moved laterally inwardly to compress the sides of the book body adjacent the back.
Claim 15
Dependent Claim 63 words
A book binding machine as claimed in claim 12, wherein said hot plate sections are formed with cooperating recessed parts which, when said hot plate sections are disposed in their laterally outer positions, can receive the longitudinal elements for forming the case retaining shoulders and which upon inward movement of the hot plate sections, can press said longitudinal elements against the book body.
