ABSTRACT:
BACKGROUND
The present invention relates to a turnover mechanism and more particularly to an improved turnover mechanism for inverting sheets that are fed to it and re-routing the movement of the sheets from one direction to another direction.
In the printing of documents comprising a number of sheets, the sheets are fed from a printer to various mechanisms which perform certain operations on the sheets, including assembling the sheets together in a particular order. It often occurs that in presenting the individual sheets to the various mechanisms, the sheets must sometimes be inverted and/or the order in which they are printed may need to be reversed or changed. In addition, in view of the location of the various mechanisms which may perform additional operations on the sheets, it may be necessary to reroute the sheets to different directions.
A number of mechanisms have been devised which will invert sheets and present them to additional mechanisms which will perform other operations on them. However, existing machines do not have the necessary versatility to invert the sheets and present them to any additional mechanisms which will perform other functions on them in the order which a particular document requires. Depending on the location of the additional mechanism which will perform other operations on the sheets it sometimes necessary for the sheets to be removed from the turnover mechanism and physically move them to the other mechanisms.
OBJECTS
The present invention overcomes these difficulties and has for one of its objects the provision of an improved sheet turnover mechanism which is versatile.
Another object of the present invention is the provision of an improved turnover mechanism which will turn the sheets over and present them to other mechanisms in either the same order or the reverse order from which they are presented to the turnover mechanism.
Another object of the present invention is the provision of an improved turnover mechanism in which the same mechanism can present the sheets in the desired order.
Another object of the present invention is the provision of an improved turnover mechanism in which the same mechanism can route the sheets to different directions either in the same order in which they are presented to the turnover mechanism or in the reverse order.
Other and further objects will be obvious upon the understanding of the illustrative embodiment about to be described, or which will be indicated in the appended claims, and various advantages not referred to herein, will occur to one skilled in the art upon employment of the invention practice.
