Transfer printing station for parallel processing of two recording medium webs

A transfer printing station for an electrographic printer or copier device for parallel printing of two recording medium webs having margin perforations that are guided next to one another in close proximity in a region of a transfer printing station and that includes a conveyor means that transports the recording medium webs through the transfer printing station in parallel, comprising:

• endless belts arranged in a region of the margin perforations of the recording medium webs,
• axially spaced, motor-driven pulleys over which said endless belts are guided,
• dog pins arranged on an outside circumferential surface of the endless belts, said dog pins including a cylindrical collar which is adjoined by a tapering head part, whereby, for conveying the recording medium webs, said dog pins engage into the margin perforations of the recording medium up in to a region of said collar in a region of a conveying path between the pulleys,
• recording medium positioning devices arranged in a region of the pulleys that guides the recording medium upon engagement and disengagement of the dog pins during the rotation of the pulleys in a region of the head part of the dog pins such that the margin perforations are not deformed, the recording medium positioning devices include:
• a guide element that lifts the recording medium in a region of the pulleys from a position with said margin perforations about said cylindrical collars to a position engaging said tapered head part as the recording medium travels over said pulleys, and
• a supporting means that supports the endless belt in a region of the conveying path between the pulleys and that has allocated hold-down elements for the recording medium.
