Abstract:
A process for high pressure embossing a single ply of paper and the paper produced thereby. The embossing process requires two rolls, a pattern roll 30 and an anvil roll 32. The rolls are loaded together at a pressure of at least 1000 psi at the nip. A single ply of paper is embossed in the nip. The embossments of the paper do not extend outwardly beyond the thickness of the paper to have any out-of-plane deformation. The embossments are typically glassined. The resulting paper has an aesthetically pleasing appearance, without undue loss of tensile strength from the embossing process.
Abstract:
Sheet material is deformed, for example crimped or bulked by feeding it to the surface of a rotating roll having a multiplicity of depressions in its surface and pressing the material against the roll surface, the material being fed to the roll at a rate exceeding the linear peripheral speed of the roll. Examples of materials which may be so deformed are filaments consisting of or containing thermoplastic polymers, woven and non-woven fabrics, thermoplastic sheets, paper and metal foils. Preferably, the roll surface consists of sintered particulate material, the depressions being the voids between adjacent particles.
Abstract:
A recording-medium binding device includes a first tooth row including plural teeth and a second tooth row including plural teeth. The first and second tooth rows include a central region and end regions. The plural teeth of each of the first and second tooth rows include at least one tooth disposed in the central region and at least one tooth dispose in each of the end regions. In a process of pinching the recording medium batch, the at least one tooth of the first tooth row in the end region and the at least one tooth of the second tooth row in the end region pinch the recording medium batch earlier than the at least one tooth of the first tooth row in the central region and the at least one tooth of the second tooth row in the central region.
Abstract:
According to an aspect of the present invention, there is provided a sheet processing device including a first teeth portion, a second teeth portion that clamps and binds a sheet bundle with the first teeth portion, a first support portion supporting the first teeth portion, a shaft, and a second support portion supporting the second teeth portion. The second support portion includes first and second arm members integrally supported to be capable of swinging around the shaft between a binding position in which the second teeth portion clamps and binds the sheet bundle with the first teeth portion and a standby position in which the second teeth portion is apart from the first teeth portion. The second arm member is provided over the first arm member so as to cover a part of the first arm member.
Abstract:
A sheet processing apparatus includes a first binding unit configured to bind a sheet bundle; a second binding unit with greater number of bindable sheets than number of bindable sheets of the first binding unit; and a number-of-sheets determining unit configured to determine whether number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit. The first binding unit moves to a binding position, and if the number-of-sheets determining unit determines that the number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit, the first binding unit moves away from the binding position. When the number-of-sheets determining unit determines that the number of to-be-bound sheets exceeds the number of bindable sheets of the first binding unit, the second binding unit moves to the binding position.
Abstract:
A staple-less binding unit is provided with upper and lower die portions having pluralities of concave and convex teeth engaging with each other. A control portion causes the staple-less binding unit to carry out a binding process of binding a sheet bundle by biting the sheet bundle by the upper and lower die portions and to carry out a cleaning process of engaging the upper and lower die portions in a non-binding process in which no binding process is carried out.
Abstract:
The present invention is to provide a sheet processing device including: a receiving tray capable of accommodating therein a sheet having, at a part thereof, a protruding portion and a sheet not having the protruding portion in a mixed state; a first binding member that binds the accommodated sheet bundle at a substantially center thereof in a sheet conveying direction; a folding section that folds the sheet bundle bound by the first binding member in two; and a second binding member that binds protruding portions of the sheet bundle folded by the folding section on a fore edge side of the sheet bundle. With this configuration, the fore edge side of the folded and saddle-stitched sheet bundle can be bound by temporary binding. Thus, a sheet processing device capable of ensuring the security of a saddle-stitched sheet bundle can be provided.
Abstract:
A sheet processing apparatus includes: a sheet fastening unit of a pressing fastener method in which a bundle of sheets is fastened by using a pair of pressing fastener members; a conveying unit that conveys the bundle of sheets that are fastened by the sheet fastening unit; a separating unit that, after the sheet fastening unit performs a fastening operation on the bundle of sheets, moves both one and the other pressing fastener members, between which the bundle of sheets is interposed, so as to separate a sheet that adheres to the pressing fastener member; and a control unit that, after the separating unit finishes an operation to separate the sheet, controls the conveying unit so as to convey the bundle of sheets that are fastened by the sheet fastening unit.
Abstract:
A sheet binding device binds a sheet bundle by causing a movable-crimping-member moving unit to move a movable crimping member thereby holding a sheet bundle between crimping members. The movable-crimping-member moving unit includes: a link mechanism that includes a first link member rotatably connected to the movable crimping member, a second link member rotatably connected to a fixed member fixed to a device body and connected to the first link member through a connecting part; a connecting member rotatably connected to the connecting part, and capable of moving between a first position causing the link mechanism to be extended and a second position causing the link mechanism to be more flexed than in the first position; and a connecting-member moving unit that includes a rotary member capable of rotating on a displaceable rotating shaft, and reciprocates the connecting member by rotation of the rotary member in one direction.
Abstract:
A double-sided embossing folder includes a first embossing plate having a first plurality of positive embossing features disposed thereon in the shape of a first image and a first plurality of negative embossing features formed on an opposite side thereof. A second embossing plate has a second plurality of positive embossing features disposed thereon in the shape of the second image configured to mate with the first plurality of negative embossing features and a second plurality of negative embossing features formed therein in the shape of the first image configured to mate with the first plurality of positive embossing features. At least one living hinge is interposed between and integrally formed with the first and second embossing plates. Each living hinge is formed from at least one V-cut formed between the first and second embossing plates to form inwardly tapered sides.
