Abstract:
An apparatus for the transport of a band-shaped recording medium in an electrographic punting or copying device, comprising:a drive cylinder having a contact surface;a drive connected to drive said drive cylinder;a pressure cylinder displaceably mounted relative to said drive cylinder;a guide face to guide displacement of said pressure cylinder;a pressure spring effecting a contact pressure of said pressure cylinder on said drive cylinder;the recording medium being transported between said drive cylinder and said pressure cylinder by friction, and said contact surface of said drive cylinder lying adjacent the recording medium; andsaid pressure spring being positioned so that its force effect is divided into a first radial force component acting perpendicularly to the contact surface and a second force component received by said guide face so that the recording medium can be repositioned for restarting of printing following a halting of printing;said guide face defining a guide slot in which is mounted said pressure roller for guided movement, said guide slot having a guide axis at an acute angle to the contact surface.
