Definitions
- the present invention relates to a method and a paper for producing items of self-copying printed matter comprising at least two sheets combined in a so-called form set or the like.
- a so-called form set which typically comprises, for example, three or four sheets of self-copying paper with which the intention is to record notations by hand or by machine on the uppermost sheet which are automatically reproduced on the sheets lying therebeneath.
- the uppermost sheet is coated on the undersurface thereof with a so-called coated-back layer (CB-layer)
- the bottom is coated on the upper- surface there of with so-called coated-front layer (CF-layer) while the two intermediate sheets are coated with a CF-layer on the upper surfaces thereof and with a CB-layer on the under- surfaces.
- CB-layer coated-back layer
- CF-layer coated-front layer
- the properties of a self-cop ing layer are such that when a CB-layer is written upon, with a pen for example, and therewith comes into contact with CF-layer the substances present in the respec ⁇ tive CB-layer and CF-layer are chemically combined in a manner which is rendered visible on at least the sheet coated with a CF-layer.
- a first paper web is coated on one side with a CF-layer
- a second paper web is coated on one side with a CB-layer
- a third paper web is coated with a CB-layer on one side and a CF-layer on the other.
- the paper webs are then placed in the successive order in a printing machine and provided with printed text etc. , whereafter a thus printed paper web is divided longitudi ⁇ nally into narrower paper webs of a width corresponding to the width of the intended form set, and is then rolled up.
- one paper roll intended for the upper side, one paper roll intended for the underside, and the requisite number of paper rolls for the intermediate sheets are transferred to a joining machine in which the sheets in said rolls are joined together and cut into lengths corresponding to the length of the intended form set.
- the papers are also here bound together to form a form set.
- Such manufacturing processes normally use as their starting point paper which is coated in the paper mill or like establishment and which is delivered in rolls whose widths are a number of times greater than the width of the intended form set.
- the present invention relates to a method which is much simpler to perform than known methods for producing self-copying form sets or the like.
- the invention also relates to a paper whose manufac- ture is incorporated in the method according to the inven ⁇ tion.
- the present invention relates to a method for producing self-copying printed matter which comprises at least two sheets combined to form a so-called form set or the like, said sheets being coated with a copying layer and said printed matter being produced by causing printed paper webs coated with a copying layer to lie one upon the other in an intended order of sequence in a form set or the like, whereafter the paper webs are partially fastened to one another and cut to a length corresponding to the length of a form set, the method being characterize in that the paper webs are produced by coating a wide pape web, having a width corresponding to the combined width of the sheets present in at least one item of printed matter, in web sections of mutually equal widths parallel with the paper web, each of which web sections has a width corres- ponding to the width of the finished item of printed matter, where respective web sections are coated with a copying layer on one side of the paper web, on the other side thereof, or on both sides of said web section, depen ⁇ ding on whether respective web sections are
- the invention also relates to a coated paper for producing an item of self-copying printed matter comprisin at least two sheets which are coated with a copying layer, said coated paper being characterized in that a wide paper web having a width corresponding to the total width of respective sheets forming part of at least one item of printed matter is coated parallel with the paper web in web sections of mutually equal widths, said web sections each having a width corresponding to the width of a finished item of printed matter, where respective web sections are coated on one side of the paper web, on the other side thereof, or on both sides of said web depending upon whether respective web sections are intended to be
- FIG 1 illustrates very schematically an apparatus for producing paper according to the invention
- Figure 2 illustrates very schematically an apparatus for producing self-copying printed matter starting from paper manufactured in an apparatus illustrated in Fig. 1.
- Fig. 1 illustrates very schematically an apparatus for producing paper according to the invention. Manufacture of the paper is incorporated in the method according to the invention for producing self-copying printed matter.
- the self-copying printed matter referred to primarily concerns form sets comprising at least two sheets which have been coated with a copying layer.
- Fig. 1 the reference 1 identifies a first roll of wide paper which forms a wide paper web 2 extending through a coating apparatus generally referenced 3 in
- the reference 4 identifies a second roll of paper coated with a copying layer.
- Fig. 2 illustrates very schematically an apparatus in which an item of printed matter is produced with the coated paper according to the invention as its starting point.
- the reference 8 identifies means for dividing the paper - web 2 into various narrow paper webs 9,10,11,12.
- a device for combining the web sections 9-12 is constructed in a known manner so that several paper webs 9-12 will lie one upon the other in the order intended, whereafter the paper webs are partially connected together in a device 14 and cut to a length corresponding to the length, in the feed direction, of a form set 13 by means of shears 15.
- the narrow, coated paper webs 9-12 are produced by coating a wide paper web 2, having a width corresponding to the total widths of the sheets forming part of at least one item of printed matter, in web sections 16,17,18,19 of mutually equal width parallel with the paper web 2, each of the sections having a width corresponding to the width of a finished item of printed matter 13.
- Respective web sections are coated with a copying layer on one side of the paper web 2, on the other side thereof or on both sides 20,21 thereof, depending on whether respective web sections 16-19 are intended to form the uppermost sheet, the lowermost sheet or the inter ⁇ mediate sheets of a finished item of printed matter 13.
- the paper web 2 is coated with two types of copying layer.
- the first type is a so-called coated back-layer (CB-layer) and the second type is a so-called coated front-layer (CF-layer) .
- the CB-layer and CF-layer are of the kind mentioned in the introduction.
- the aforesaid web sections 16-19 are coated so that the web section 16 intended to form the top sheet of an item of printed matter is coated on its undersurface with a CB- layer, that a web section 19 intended to form the bottom sheet is coated with a CF-layer on its upper surface, and that the web sections 17,18 intended to form intermediate sheets are coated on their respective upper surfaces with a CF-layer and on their respective undersurfaces with a CB-layer.
- the rolls 23,24 are axially divided into at least two sections, and preferably into as many sections as the number of desired web sections, i.e. in the illustrated embodiment four roll sections 16,17,18,19, where in each roll section coating can be carried out or prevented irrespective of whether coating has been carried out in other roll sections or not.
- the actual coating technique and also the chemical composition of the coating layers are well known to the art and will not therefore be described in more detail.
- the coated paper 4 comprises a wide paper web 2 which is coated with copying layers in longitudinally extending web sections 16-19 in dependence on where respective web sections are to be placed in an item of printed matter.
- the wide paper web 2 has a width which is equal to the total width of the sheets forming part of solely one item of printed matter, where the web section 16 along one side edge of the paper web 2 is only coated on one side, where the web section 19 along the other side edge of the paper web 2 is solely coated on the other side, and where the part of the paper web 17,18 located between the web sections 16,19 situated along the side edges is coated on both sides.
- a coating apparatus of the kind illustrated in Fig. 1 normally has a capacity which is much greater, for example three times greater, than the capacity of a printi press, which is illustrated schematically in Fig. 2. For this reason it is therefore suitable to roll-up the coated paper 4, and to transfer such a roll of paper to a printin press for finally producing printed matter. -In this way, a coating apparatus can be used to coat paper while, for example, three printing presses can be used to finally prepare the items of printed matter.
- the coating apparatus may be incorporated with the printing press, the paper web 2 remaining unbroken through the plant.
- the paper web 2 is divided longitudinally, in accordance with the invention, into two or more narrow paper webs 9,10,11,12, where each of said narrow paper webs 9-12 corresponds to a web section 16-19.
- the narrow paper webs 9-12 are brought together, fastened to one another and cut, therewith to provide a finished intended item of printed matter. It will readily be perceived that the present inven ⁇ tion eliminates the disadvantages mentioned in the intro ⁇ duction.
- the invention enables self-copying printed matter to be produced in a highly rational manner. The method avoids the necessity of starting with wide paper webs having a given coating and requiring to be printed upon, divided into longitudinal sections and rolled onto an equal number of rolls as there are sections and to then
- O PI mount a number of different such rolls in a machine for combining various sections to form an item of printed matter.
- the coating apparatus can be re-set to coat the paper in a different manner. This also contributes to the possibility of producing relatively small editions of self-copying paper at reasonable costs. It will be understood that the invention is not restricted, to the production of form sets and neither to the production of printed matter comprising four sheets. The invention can, of course, be applied in the manufacture of any type of printed matter which includes sheets coated in various ways.
