Abstract
An embodiment of the invention is directed to a sheet, wherein a conveying direction of the sheet relative to a sheet conveying apparatus is determined; the sheet is formed with a crease along which to fold the sheet and that is smaller than or equal to 90 μM in depth and extends in a direction that crosses the conveying direction; and a grammage of the sheet is in a range of 200 to 370 g/m2.
Claims17
A sheet, wherein
- a conveying direction of the sheet relative to a sheet conveying apparatus is determined;
- the sheet is formed with a crease along which to fold the sheet and that is smaller than or equal to 90 μm in depth and extends in a direction that crosses the conveying direction;
- and
- a grammage of the sheet is in a range of 200 to 370 g/m2.
A sheet wherein:
- a conveying direction of the sheet relative to a sheet conveying apparatus is determined;
- and
- the sheet is formed with a crease that has a predetermined depth and extends in a direction that crosses the conveying direction, the predetermined depth being larger than a value below which a break-at-crease occurs when the sheet is folded at the crease and smaller than a depth above which a conveyance failure occurs due to hooking between the crease of a topmost one of a plurality of the sheets stacked on a sheet bearing unit of the sheet conveying apparatus and the crease of a sheet immediately underlying the topmost sheet in conveying the topmost sheet.
A sheet conveying apparatus comprising a conveying unit that conveys a sheet, and a sheet bearing unit on which the sheet to be conveyed is placed, wherein:
- a conveying direction relative to the sheet conveying apparatus is determined for the sheet to be placed on the sheet bearing unit;
- the sheet is formed with a crease that is smaller than or equal to 90 μm in depth and extends in a direction that crosses the conveying direction;
- and
- a grammage of the sheet is in a range of 200 to 370 g/m2.
A sheet conveying method, which comprises:
- conveying a sheet for which a conveying direction relative to a sheet conveying apparatus is determined, wherein a grammage of the sheet is in a range of 200 to 370 g/m2 and is formed with a crease that is smaller than or equal to 90 μm in depth and extends in a direction that crosses the conveying direction.
A sheet, wherein
- a conveying direction of the sheet relative to a sheet conveying apparatus is determined;
- the sheet is formed with a crease along which to fold the sheet and that extends in a direction that crosses the conveying direction;
- in case the crease is convex upward in a state that the sheet is placed on a sheet bearing unit of the sheet conveying apparatus, an upstream-side rising portion, in the conveying direction, of the crease is inclined more gently than a downstream-side rising portion of the crease;
- and
- in case the crease is concave upward in a state that the sheet is placed on the sheet bearing unit of the sheet conveying apparatus, a downstream-side falling portion, in the conveying direction, of the crease is inclined more gently than an upstream-side falling portion of the crease.
A sheet, wherein
- a conveying direction of the sheet relative to a sheet conveying apparatus is determined;
- the sheet is formed with a crease along which to fold the sheet and that extends in a direction that crosses the conveying direction;
- in case the crease is convex upward in a state that the sheet is placed on a sheet bearing unit of the sheet conveying apparatus, an upstream-side rising bent portion that connects an upstream-side rising portion in the conveying direction and an upstream-side flat portion that is located upstream of the upstream-side rising portion is smaller in curvature than a downstream-side rising bent portion that connects a downstream-side rising portion in the conveying direction and a downstream-side flat portion that is located downstream of the downstream-side rising portion;
- and
- in case the crease is concave upward in a state that the sheet is placed on the sheet bearing unit of the sheet conveying apparatus, a downstream-side falling bent portion that connects a downstream-side falling portion in the conveying direction and a downstream-side flat portion that is located downstream of the downstream-side falling portion is smaller in curvature than an upstream-side falling bent portion that connects an upstream-side falling portion in the conveying direction and an upstream-side flat portion that is located upstream of the upstream-side falling portion.
