Abstract (en)
[origin: US6322487B1] The present invention is generally directed to providing a method and apparatus for accurately and efficiently folding a flat product (e.g., a web of paper or signatures obtained therefrom) during its delivery. Exemplary embodiments provide a single device for performing the two functions of folding and decelerating flat products. Rotatable seizing elements of a deceleration drum interface with any known folding cylinder having a known tucker blade assembly. As such, the accurate and mark-free folding of a conventional jaw folder can be achieved with any desirable paging, including the wide maximum paging range typically associated with rotary tucker blade folders. A deceleration drum according to the present invention can interface with any folding cylinder having a tucker blade assembly used to create a cross-fold, and can thereby replace any conventional combination of a folder (e.g., rotary tucker blade folder or jaw folder) and associated downstream deceleration device. Seizing devices associated with the deceleration drum create a fold off of a fixed (e.g., a non-retractable) or a retractable tucker blade of the folding cylinder, each seizing element acting as a jaw which removes the signature, and creates the fold during product deceleration and delivery.
