Abstract
An apparatus which compensates for the velocity mismatch between adjacent sheet transports. A plate, interposed between the sheet transports, supports the sheet until the leading edge thereof advances from the first sheet transport to the second sheet transport. When the leading edge of the sheet is received by the second sheet transport, the plate pivots away from the sheet to a location remote therefrom. Since the first sheet transport advances the sheet at a greater velocity than the second sheet transport, the sheet forms a buckle to compensate for the velocity mismatch between sheet transports.
Claims16
An apparatus that compensates for velocity mismatches in transporting a sheet along a path, including:
- a first sheet transport adapted to advance the sheet along a first portion of the path at a first velocity.
- a second sheet transport adapted to advance the sheet along a second portion of the path at a second velocity with the first velocity of said first sheet transport being greater than the second velocity of said second sheet transport;
- and
- means, interposed between said first sheet transport and said second sheet transport, for supporting the sheet as the sheet moves from said first sheet transport to said second sheet transport, said supporting means being adapted to move away from the sheet when the leading edge of the sheet is received by said second sheet transport so as to form a buckle in the sheet due to said second sheet transport advancing the sheet at a slower velocity than said first sheet transport.
An electrophotographic printing machine in which a copy sheet advances along a path so that a toner image is transferred thereto from a photoconductive member, wherein the improvement includes:
- a first sheet transport adapted to advance the copy sheet along a first portion of the path at a first velocity;
- a second sheet transport adapted to advance the copy sheet along a second portion of the path at a second velocity with the first velocity of said first sheet transport being greater than the second velocity of said second sheet transport;
- and
- means, interposed between said first sheet transport and said second sheet transport, for supporting the copy sheet as the copy sheet moves from said first sheet transport to said second sheet transport, said supporting means being adapted to move away form the copy sheet when the leading edge of the copy sheet is received by said second sheet transport so as to form a buckle in the copy sheet due to said second sheet transport advancing the sheet at a slower velocity than said first sheet transport.
