Abstract
An apparatus (10) for folding sheets (17) and corresponding method, comprising at least a conditioning body (11), at least a folding unit (13) and at least an extraction mean (12) suitable to fold sheets (17) in sequence of variable formats, maintaining high cadences and at the same time simplifying the structure for the maintenance operations and/or format-changes.
Claims15
A folding apparatus for sheets, comprising at least a conditioning unit, at least an extraction mean mobile along the axis of said conditioning unit and at least a folding unit coordinated with said conditioning unit, said conditioning unit being associable in a temporarily stable manner with a sheet feeding unit, wherein said conditioning unit comprises a containing body and a housing guide associated with a limiting body.
A method to fold sheets by using a folding apparatus, said method comprising:
- a step of introducing at least a sheet into a conditioning unit,
- a step of winding said sheet inside a containing body of said conditioning unit to create a tubular element,
- a step of extracting said tubular element by an extractor mean from said containing body,
- a step of inserting said tubular element into a folding unit,
- a step of compressing said tubular element to obtain a folded sheet, and
- wherein said step of introducing provides that said sheet reaches a limiting body (23) associated with a housing guide of said conditioning unit.
