METHODOF PRODUCING MULTIPLE AND BACKED COPIES.
Specification of Letters Patent. I Application filed. February 3, I905. Serial N0} 244,017.
Patented June 25, 1907.
To all whom it may concern: i
Be it known that I, FRIEDRICH GUSTAV JULIUS POST, a subject of the German Emperor, and a resident of Hamburg, in the German Em ire, have invented certain new and useful mprovements in the Method of Producing Multiple and Backed Copies, of.
which the following is a full, clear, and exact specification. 1
This invention has for its object the treatment of copies while still damp for the purpose of obtaining backed (back-lined) or strengthened (stiffened) copies or of multiplying them. In order to attain the-desired object the copies while still damp are again submitted to pressure together with paper rolls or paper Webs, presenting copying or adhesive properties.
In the accompanying drawing I have illustratd diagrammatically by Fi ures 1-5 several constructional formsof a evice for carrying the invention into practice.
' In the arrangement illustratedifn F 1 a dampened web of copyin paper 0 passes between pressure rollers a. of 9. copying machine, one of the rollers being covered with a suitable covering a of rubber or the like, or, as shown in Fig. 4, three rollers a. having an endless apron a passing around them maybe substituted. A sheet of manuscript, (1 to be copied accompanies the web 0 through the copying machlne, and said web is then conducted through pressure rollers g, g, in company with a suitably prepared web j stored on a roller 6. The webs c andfleaving these pressure rollers ma then be wound upon a suitable drum h. is have yielded its moisture to the web f, it is, of course, impossible for the ink to run. Whether the web f consists of copying paper or is provided with an adhesive coating (of gum arabic, dentrine, or the like) either a second copy or a perfectly smooth backed original copy, is obtained ;.in either case it is not possible for the ink on these copies to run. If desired it is ossible to again separate the backed copy, y stripping off the copying paper from the gummed paper immediately after the sticking together of the websand they are still in a moist condition. When this is done there is obtained upon the gummed paper an exceedingly clear and sharp positive copy, while the original copy (that is to say the copying paper which "has the copying web 0 will been stripped off) will have takenup a portion of the adhesive substance, and will have thus become somewhat stiffened. This copy may then be caused to adhere, by means of the adhesive, substance that it has taken up, to another web of ordinary paper, while a thin, transparent web may be applied to the side of the paper web f which is still adhesive.
In the arrangement illustrated in Fig. 2, one of the pressure rollers 9 may be replaced directly by the paper roller e f. This arrangement is preferable for cases in which the paper roller f is used moist, as in this case but slight pressure is required for obtaining the copy.
In the arrangement illustrated in Fig. 3,
\ both pressure rollers are dispensed with, by
carrying the web of copying paper c directly against andaround the paperroller e f. If the web of copying paper is permitted to remain -upon the web f of gummed. paper,
only one copy is obtained, but this, is sharp,
clear and considerably strengthened, while 1t is already so dry that running of the i1npres-. sion is impossible. In order to obtain a second copy simultaneously, a second web of copying paper 0 must be caused to ass through t e machine with the first, as shown in Fig. 4; this second web 0 being wound upon a separate receiving drum k. If desired, however, all three Webs-oi pa er f, c and 0 may be wound together upon te same drum h (see Fig. 5), thesim le copy 0 being then wound therefrom on to t e drum it, while the backed. copy cf is wound upon another upon both sides, in which case a web of copyaper is a plied to each side. aving ful y described my invention what I do claim and desire to secure by Letters Patent is': a 1. The method of producing copies consisting in'subj eating to pressure a dampened web of copying material acc mpanied by manuscript shcets and again subjecting the dam pened 'web 'topressure accompanied by an adhesive web.
2. The method of producing 00 ies, consisting in subjecting to pressure a ampened web of copying material accompanied by manuscript sheets, again sabj ccting the dampened Web to pressure accompanied bv an ,adhesive web and then separating the dam- Web', separatin'g the dampened and adhesive webs and applying a transparent Web to the separated'adhes'ive web.
4, The method of producing copies, con- ,sisting in subjecting to pressure a dampened web of copying material accompanied by manuscript sheets, subjecting thedam ened web to pressure accompanied by an ad esive web, separating the dampened and adhesive Webs and applying a stiffening web to the separated dampened web.-
5. The method of producing copies, consisting in subjecting to pressure a dampened Web of" copying material accompanied by manuscript sheets, subjecting the dampened Web to pressure accompanied by an adhesive Web, separating the dampened and adhesive webs, a plying a stifiening web to the'sepaarated ampened web and applying a transparent web to the separated adhesive web.
6. The method of producing copies, consisting in subjecting to pressure two Webs of dampened copying material accompanied by a sheet of manuscript, applying an adhesive Web to one of the Webs of copying material, and separating the second copying web from the adhered copying and adhesive webs.
