An apparatus adapted to ink a flat printing surface h comprises a pair of reciprocable forme rollers c, d, a pair of supporting rollers, Fig. 2 (not shown), coaxial with each forme roller and of the same diameter as the respective forme roller, a pair of rails g engaged by said pairs of rollers so as to lower the forme rollers while they are rotating on to the surface h, a pair of stationary driven distributing rollers e, and a messenger roller b controlled by cam means so as to supply ink to the rollers e once in every cycle of movement of the forme rollers. The circumference of each forme roller is equal to the length of the surface h and the forme rollers are mounted as idler rollers, i.e. each roller transfers ink to the forme merely by the pressure exerted by its own weight. The spindles of the forme rollers are provided with sleeves adjustable with respect to the roller bearings to prevent axial displacement. gripper-fingers 142 engaging its leading edge is stripped or separated from the cylinder when the grippers are opened adjacent to delivery rollers 42 and guides 43, by a weighted member 160 freely pivoted on the gripper-shaft 143. Just before the grippers are opened, the engagement of pins 163 on the member 160 with the gripper fingers holds the stripper part 161 of the member 160 within the cylinder surface as shown in Fig. 5, but when the grippers are subsequently opened, the movement of the fingers 142 allows the part 161 to project from the cylinder and separate the leading edge of the sheet from the cylinder. The gripper shaft 143 carries at one end an arm 147, Fig. 2 (not shown), to which is attached a swing-over spring 144 holding the shaft in either the open or the closed position of the grippers. Opening and closing of the grippers is effected respectively by two pins 151, 152, Fig. 4 (not shown), which engage an arm 148 on the gripper shaft 143. The cylinder 30 carries the original copy sheet in an electrostatic copying machine as described in Specification 1,032,951.
