Abstract
Abstract A record book or pad and a method of manufacturing such a book or pad has a stack of sheets in sets A. Each set A consists of a primary sheet P disposed between secondary sheets OS and US. Both faces of the sheet P are provided with a reactive coating 4 of duplicating material and each face of the secondary sheets OS and US which opposes the primary sheet P in the set is provided with reactive coatings 5 of duplicating material. When a marking is applied to the sheet OS for recording a message, pressure from that marking transfers through the sheet OS causing the coatings 4 and 5 between the sheets OS and P to inter-react and form a duplicate marking on a one face of the sheet P. Similarly when a marking is applied to the secondary sheet US, pressure from that marking transfers through the sheet US causing the coatings 4 and 5 between sheet P and US to inter-react and form a duplicate of the marking on the second face of the sheet P. The sheets OS and US may be removed from the book by tearing along perforations 10 and such removed portions may carry low tack adhesive 21. Low tack adhesive 22 may be provided on the secondary sheets OS and US to contact the primary sheet P in the respective sets along the spine part 2 of the book.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
298 words
A method of manufacturing a record book and comprising the following steps, providing record sheets and secondary sheets, binding said record and secondary sheets to provide a spine, arranging said record sheets and secondary sheets in overlying relationship such that a face of a secondary sheet opposes a face of an adjacent record sheet, providing a reactive coating of duplicating material to said opposing faces of said record and secondary sheets, applying pressure to the secondary sheet causing the reactive coatings on the adjacent opposed faces of the secondary and record sheets to inter-react and thereby, providing a copy of the mark or impression so applied on the face of the record sheet, forming said record and secondary sheets in sets such that each set includes a record sheet and two secondary sheets, providing reactive coating on one face only of each of said two secondary sheets of said sets so that the two secondary sets have said one faces that are adjacent to and oppose the faces of the record sheet so provided with said reactive coating that, applying pressure on a first secondary sheet in this set transfers that marking through the first secondary sheet, causing the reactive coatings between one face of the record sheet and the opposing face of the first secondary sheet to inter-react, providing a copy of that marking on said one face of the record sheet, said pressure applying step on a second secondary sheet achieving transfer of that marking through the second secondary sheet thereby, causing the reactive coating between the second face of the record sheet and the opposing one face of the secondary sheet to inter-react thereby, providing a copy of that marking on the second face of the record sheet, retaining said record sheets in the book.
Claim 2
Independent Claim
298 words
A method of manufacturing a record book and comprising the following steps, providing record sheets and secondary sheets, binding said record and secondary sheets to provide a spine, arranging said record sheets and secondary sheets in overlying relationship such that a face of a secondary sheet opposes a face of an adjacent record sheet, providing a reactive coating of duplicating material to said opposing faces of said record and secondary sheets, applying pressure to the secondary sheet causing the reactive coatings on the adjacent opposed faces of the secondary and record sheets to inter-react and thereby, providing a copy of the mark or impression so applied on the face of the record sheet, forming said record and secondary sheets in sets such that each set includes a record sheet and two secondary sheets, providing reactive coating on one face only of each of said two secondary sheets of said sets so that the two secondary sets have said one faces that are adjacent to and oppose the faces of the record sheet so provided with said reactive coating that, applying pressure on a first secondary sheet in this set transfers that marking through the first secondary sheet, causing the reactive coatings between one face of the record sheet and the opposing face of the first secondary sheet to inter-react, providing a copy of that marking on said one face of the record sheet, said pressure applying step on a second secondary sheet achieving transfer of that marking through the second secondary sheet thereby, causing the reactive coating between the second face of the record sheet and the opposing one face of the secondary sheet to inter-react thereby, providing a copy of that marking on the second face of the record sheet, retaining said record sheets in the book.
Claim 3
Dependent Claim
39 words
The method according to claim 1 further including the step of providing a line of weakness adjacent to the spine of the book to facilitate removal of those portions of each secondary sheet from the spine of the book.
Claim 4
Dependent Claim
49 words
The method according to claim 1 further comprising the step of applying to each secondary sheet having such a reactive coating a region of low tack adhesive, whereby that secondary sheet or portion thereof having such a low tack adhesive can be conveniently adhered temporarily to a receptive surface.
Claim 5
Dependent Claim
38 words
The method according to claim 3 further including the step of applying to each face of the record sheet a localized release agent to underlie the low tack adhesive carried by the adjacent secondary sheet in the set.
Claim 6
Dependent Claim
29 words
The method according to claim 1 further including the step of applying an adhesive to secure the record sheets and secondary sheets of a set together along common edges.
Claim 7
Dependent Claim
86 words
The method according to claim 3 further including the step of applying to each secondary sheet having said reactive coating region of low tack adhesive, said region low tack adhesive being provided in the spine of the book whereby said record and second secondary sheets are secured together in sets along a common edge thereby forming discrete sets, and whereby each region of low tack adhesive remains in the spine of the book particularly when portions of the secondary sheets are so removed from the book.
Claim 8
Independent Claim
265 words
A method of manufacturing a record book which comprises forming record sheets each of which record sheet has both faces thereof provided with a reactive coating of duplicating material; forming secondary sheets each of which secondary sheets has a single face thereof provide with a reactive coating of duplicating material; collating the record sheets and secondary sheets into sets, each set having a record sheet and two secondary sheets in overlying relationship and in each set positioning the record sheet between the two secondary sheets with the single face of each secondary sheet having said reactive coating being disposed adjacent to and opposing a face of the record sheet having said reactive coating whereby application of a mark by pressure on a first secondary sheet in a set causes pressure transfer of that marking through said first secondary sheet and the reactive coatings between one face of the record sheet in said set and the opposing face of said first secondary sheet to inter-react and provide a copy of that marking on said one face of the record sheet and application of a mark by pressure on the second secondary sheet in said set causes pressure transfer of that marking through said second secondary sheet and the reactive coatings between the second face of the record sheet in said set and the opposing face of said second secondary sheet to inter-react and provide a copy of that marking on said second face of the record sheet; collating several said sets in overlying relationship and binding, said sets together at a spine part of the book.
