J) Ie invention relates to a Kon taktko.piervori'iohtung »in which the traced material is clamped between two relatively thin flexible foil frames * which in the Y / really form a cylinder, which is an elongated light source _? aB »an auricular tube, concentrically surrounding it. In these known devices, the foils are detachably fastened to their ßändexa profiled rails extending parallel to the cylinder axis, üio in a suitable manner on the frame or ß-housing body carrying the light source,

These devices known type have a langgeetreoisteft mostly hollow trapezoidal Ouerschnitt aiifweleenden Fuas "OCE the light source transmits and rails Üqt Poli bodies are fixed to the side Begrenzunrswänden. In these designs, the aim was also to - the stops seemed to come closer to each other »« in order to achieve the largest possible surface area in the direction of the start of the copier cylinder.

According to the invention, this is basically achieved by the fact that at least the inner film, which is transparent to the light source, is made of a known articulated and hardenable synthetic resin produced is "ge ^ ebenanf alls' with and inserted into the starting offered profiled £ another holding rail, the sinner both foils are at one .END the dis ^r hinged © Irom & el forming film webs on the frame body or better to the inner wall of a UE-ehiiusekörpers permanently attached "kind of Erfinuun ^ is now the soluble tape / 'so the other% hands aex outer film _$ with a very thin' naoh inside abgöbo ^ enes ilandlwisjte provided" against which the blunt ^ estosscne hand the inner foil and possibly also abet ^ tst the traced »In this way it is erx-elcht» that the yolienrands in & $ r parting line of the Copy drum without gap

In order to press the pauagut well against the d & 8 negative in the entire plan area of the printing drum during exposure, a further development of the invention is proposed »to design the detachable locking members so that the two poles are not only under tension radially, but also in the direction of the copier drum , and daaa slight Paasun ^ enickeiten as well as different thickness of the Pausgutea are automatically compensated for when the closure is made, without this nocJamala g ^ löat w & Tüen
