摘要： A sheet supporting drum during development in machines for electrostatically preparing printing matrices is disclosed. The drum is provided with front or head and rear or tail grippers, of which the rear or tail gripper is displaceable, wherein the latter comprises a fillet or section carried by arms passing through slots in the drum shell and mounted on a rotable common shaft carried by bearing means that can be angularly displaced about an axis coincident with the drum axis of rotation.

摘要： Improvements to a matrix supporting device in electrostatic development apparatus, wherein the pliers retaining the matrix rear portion can be moved along a cylindrical surface to which said matrix is intended to adhere. A cam controlled oscillating support provides for a magnetic roller and its associated toner carrying tray to be moved away from the cylindrical surface to allow for passage of the pliers.
