Abstract

1,079,154. Sheet delivery; apparatus. G. SCHWIENBACHER, [trading as WISSENSCHAFTLICHES FORSCHUNGSINSTITUT GEORGES SCHWIENBACHER]. Nov. 18, 1964 [Nov. 19, 1963], No. 46893/64. Heading B6H. [Also in Division G2] An original 18 (Fig. 2) in a holder 17 comprising a flexible sheet with, at one end, a guiding portion 6 having a portion folded back 19, is covered on the lower side by a negative paper 20 for the diffusion process and fed guiding portion first, by a belt over a continuous exposure device 14 (Fig. 1); the document holder and original are then separated from the negative by fixed plate 5 and operate a lever which causes a positive paper 7 held by the lever to fall between rollers 9 and 10 which transport it until it hits wall 13; the negative is carried by rollers 10 through a developer bath 11, and on emerging, still wet, contacts and picks up the positive; the positive and negative are pressed together by rollers 15 and ejected.
