Device for completely automatic retraction of a material run from a printer roll changer generally useful in printing technology avoids manual position engagement (sic) during retraction of a paper run

摘要

Device for completely automatic retraction of a material run from a roll changer in the upper part of a printing machine with a guide rail (01) along the material run path where the guide rail (03) is led around a spherical roller (03) and the return point (U) of the guide rail is in direct proximity to the end position of the spherical roller. The roll changer can be used in a first or second position, where in the first position a drive for uncoiling (sic) the material roll is deactivated and in the second position the drive for uncoiling the material roll is activated. An independent claim is included for a process for completely automatic retraction of a material run from a roll changer in the upper part of a printing machine.
