Adaptive registration/binding apparatus for preparing collations
View Patent ↗An apparatus for preparing a collation of sheets for folding operations. The system includes a registration device including multiple registration stations and a conveyance device for transporting the collation to one of the registration stations. Each registration station is adapted to register the edges of the collation based upon a desired edge geometry. A processor determines the fold configuration of the collation and determines the edge geometry thereof based upon the fold configuration of the collation. The processor selects one of the registration stations based upon the fold configuration and then controls the conveyance device to transport the collation to the selected registration station. The registration station selected may also be based upon the thickness of the collation and a desired location for binding the collation.
1. An apparatus for preparing a collation of sheets for a folding operation, comprising:
a registration device adapted to receive a collation of sheets;
the registration device having opposed registration members defining opposed registration surfaces operative to respectively engage leading and trailing edges of the collation such that the opposed registration surfaces each define an angle with respect to a vertical plane and respectively misalign the leading and trailing edges of the collation prior to a folding operation, and
a conveyance device operative to transport the collation into and out of the registration device.
2. The apparatus according to claim 1 , further comprising a displacement mechanism operative to oscillate the registration members into and out of engagement with the leading and trailing edges of the collation.
3. The apparatus according to claim 1 further comprising a means for displacing at least one of the registration surfaces such that the angle of the at least one of the registration surfaces is variable with respect to the vertical plane.
4. The apparatus according to claim 1 , further comprising a means for binding the collation.
5. The apparatus according to claim 4 , wherein the binding means binds the collation at a location proximal to a centerline of the collation.
6. The apparatus according to claim 1 further comprising a folder operative to fold the collation about a fold axis.
