Abstract
A turn-over apparatus for a printer for printing on both sides of a web-shaped recording medium has two acutely angled deflectors to turn the recording medium over. The angles of the deflectors are such that the converging ends of the deflectors are spaced apart. Automatic threading of the recording medium is provided.
Claims16
A turnover apparatus for a band-shaped recording medium comprising:
- a paper admission channel and a paper discharge channel that are arranged next to one another in close proximity,
- a first turning triangle allocated to the paper admission channel and a second turning triangle allocated to the paper discharge channel, each respectively comprising a straight deflection element and an oblique deflection element arranged at an angle of about 45.degree. thereto, whereby
- a) the band-shaped recording medium, proceeding from the paper admission channel, is guided via the deflection elements of the turning triangles up to the paper discharge channel such that the band-shaped recording medium folds completely over around a boundary line between the channels, and
- b) the turning triangles are arranged in a plane parallel to the paper admission channel and paper discharge channel turned relative to one another by a predetermined spread angle such that the band-shaped recording medium is spread in the region between ends of the oblique deflection elements tapering toward one another, whereby the spread angle exhibits a minimum value with reference to the deflection radius of the deflection elements employed that band edges of entering and exiting portions of the band-shaped recording medium that are directed toward a middle can be guided adjoining one another in close proximity in a region of the boundary line between the channels.
