Abstract

949,590. Feeding sheets. J. HALDEN & CO. Ltd. May 17, 1962 [June 6, 1961], No. 20311/62. Heading B6B. [Also in Division G2] The feed board of a photo-copying machine (see Division G2), embodies suction means serving to retain manually introduced sheets to be exposed in position for introduction to the nip rollers. Three embodiments of such feed boards which are attached to the machine so that the left-hand side abuts the rollers, are shown in Figs. 2, 3 and 4. Suction is applied through lines 25, 25 and 43, respectively, and the respective rollers 26, 33 and 41 may be neutrally or positively rotated.
