Abstract
A turnover device for turning a web-shaped recording medium over between two electrographic printer or copier devices working in tandem mode, the crossing point of the turning elements is arranged offset a distance .pi.r/.sqroot.2 in the direction of the deflector element relative to the middle of the supplied recording medium, taking the cross sectional dimensions of the turning elements into consideration. A lateral offset of the recording medium is thereby avoided.
Claims14
A turnover device for turning a web-shaped recording medium having a first and second lateral edge, said medium supplied to the turnover device in a prescribed delivery attitude, comprising:
- two crossed turning elements and a deflector element arranged laterally with respect thereto;
- and
- a crossing point of the turning elements is arranged offset in the direction of the deflector element, such that the recording medium departs the turnover device in a turned attitude wherein said second lateral edge aligns with said first lateral edge;
- and
- wherein said turning elements have a circular cross section with a prescribed radius r, the crossing point of said turning elements being arranged offset from the center line of the recording medium corresponding to a distance of .pi.r/.sqroot.2.
A method of turning over a web-shaped recording medium, comprising the steps of:
- providing a first turning element, a second turning element and a deflector element;
- arranging the first and second turning elements crossed;
- arranging the deflector element laterally of the crossed turning elements;
- circulating the web-shaped recording medium partially around the first turning element, then partially around the deflector element, then partially around the second turning element;
- arranging the crossing point of the first and second turning elements offset from a centerline of said medium toward said deflector element;
- and
- wherein said step of providing first and second turning elements is further defined as providing circular cross section turning elements having radius "r";
- and said step of arranging the crossing point is further defined as offsetting said crossing point a distance of .pi.r/.sqroot.2 from the centerline of the recording medium.
