Abstract
An individual sheet overlapping mechanism includes holding cylinders having paper edge holding mechanisms capable of holding a front edge portion in a conveying direction of a first individual sheet and that are provided rotatably along the conveying direction of the first individual sheet. The holding cylinders are configured to wrap the first individual sheet that has reached the holding cylinders around the holding cylinders by the paper edge holding mechanisms, release the first individual sheet at a timing when a second individual sheet has reached the holding cylinders, and stack the first individual sheet on the second individual sheet.
Claims5
An individual sheet overlapping mechanism for overlapping a first individual sheet on a second individual sheet, the first individual sheet being conveyed from an upstream side and the second individual sheet being conveyed thereafter and having a length in a conveying direction which is longer than a length in the conveying direction of the first individual sheet, the individual sheet overlapping mechanism comprising:
- a holding cylinder that includes a paper edge holding mechanism capable of holding a front edge portion in the conveying direction of the first individual sheet and that is provided rotatably along the conveying direction of the first individual sheet,
- the holding cylinder being configured to wrap the first individual sheet that has reached said holding cylinder around said holding cylinder by the paper edge holding mechanism, release said first individual sheet at a timing when the second individual sheet has reached said holding cylinder, and stack said first individual sheet on said second individual sheet.
An individual sheet overlapping method for overlapping a first individual sheet on a second individual sheet, the first individual sheet being conveyed from an upstream side and the second individual sheet being conveyed thereafter and having a length in a conveying direction which is longer than a length in the conveying direction of the first individual sheet, the individual sheet overlapping method comprising:
- employing an individual sheet overlapping mechanism comprising a holding cylinder that includes a paper edge holding mechanism capable of holding a front edge portion in the conveying direction of the first individual sheet and that is provided rotatably along the conveying direction of the first individual sheet
- to wrap the first individual sheet that has reached the holding cylinder around said holding cylinder by the paper edge holding mechanism, and then release said first individual sheet at a timing when the second individual sheet has reached said holding cylinder, thereby stacking said first individual sheet on said second individual sheet.
