A pressure sensitive adhesive particle includes a styrene resin that contains, as polymerization components, styrene and a vinyl monomer other than styrene; and a (meth)acrylate resin that contains, as polymerization components, at least two (meth)acrylates that account for 90 mass % or more of all polymerization components of the (meth)acrylate resin, in which the pressure sensitive adhesive particle has a sea phase that contains the styrene resin, and island phases that are dispersed in the sea phase and contain the (meth)acrylate resin, the pressure sensitive adhesive particle has at least two glass transition temperatures, and a difference between the lowest glass transition temperature and the highest glass transition temperature is 30° C. or more, and in a cross section of the pressure sensitive adhesive particle, an area ratio of the island phases is 30% or more and 85% or less.

Provided are a post-processing apparatus, an image forming apparatus, and a post-processing method capable of avoiding the occurrence of a malfunction due to a failure to discharge a sheet bundle after a binding process. A plurality of sheets is loaded on a stack tray. A staple unit binds the plurality of sheets. A discharge roller discharges the sheet bundle bound by the staple unit from the stack tray. Each time a sheet is conveyed to the stack tray, an aligning unit moves between a first position in contact with the sheet loaded on the stack tray and a second position separating from the sheet. A detection processing unit detects a failure of discharging the sheet bundle by the discharging roller. A stop processing unit can stop the operation of the aligning unit when the discharge failure is detected by the detection processing unit.

A post-processing apparatus includes a binding device, a closing device, a driver, and a changeover switch. The binding device binds a sheet bundle. The closing device closes an entrance to a binding position at which the binding device binds the sheet bundle. The driver moves the closing device to a closing position to close the entrance. The switch performs switching to implement a state in which the binding device is able to bind the sheet bundle when the closing device moves to the closing position. The closing device includes an avoidance operation portion to move to the closing position to operate the switch, and a drive coupler coupled to the avoidance operation portion to move the avoidance operation portion to the closing position. A coupling state between the avoidance operation portion and the drive coupler is released when movement of the avoidance operation portion to the closing position is prevented.

Articles, for example multi-ply fibrous structure-containing articles such as multi-ply sanitary tissue products, containing two or more fibrous structure plies, and more particularly to multi-ply articles containing two or more fibrous structure plies having a plurality of fibrous elements wherein the articles exhibit improved bulk and absorbent properties compared to known articles and methods for making same, are provided.

There is provided a method of manufacturing sachets. The method involves moving a web of semi-rigid material through a cutting station and simultaneously cutting a discrete cut in the web of semi-rigid material while the web of semi-rigid material continues to move through the cutting station. The method also includes sandwiching the web of semi-rigid material between a first flexible web of material and a second web of flexible material such that the first web of flexible material seals the discrete cuts in the semi-rigid web of material and the second web of flexible material forms a continuous elongate reservoir with the web of semi-rigid material. There is also provided an apparatus for cutting a web of material. The apparatus has a cutting roller and at least one cutting element protruding beyond the exterior surface of the roller, wherein the cutting element has a cutting profile that is at least partly a zigzag shape. Another apparatus for cutting a web of material the apparatus has a first cutting element and a second opposing cutting element, each cutting element having a cutting profile that is at least partly a zigzag shape. Each cutting element is associated with a cam and a rail that are arranged such that the first cutting element follows a path and the second cutting element follows a path that mirrors the path of the first cutting element. The paths have adjacent sections and/or intersecting sections in which the cutting elements come together to discretely cut the web of material while leaving the material intact.

An electric stapler includes a clamp part that is configured to include a first wall portion and a second wall portion for gripping a paper bundle, a penetration part that causes a staple to penetrate the paper bundle gripped by the clamp part, a clinch part that bends the staple penetrating the paper bundle to bind the paper bundle, a gripping release detection unit that detects that the paper bundle is released from gripping after the first wall portion moves in the direction of separating from the second wall portion from a state where the paper bundle is gripped by the clamp part; and an output unit that, after it is detected that the paper bundle is released from gripping of the clamp part, outputs a gripping release signal indicating that the paper bundle is released from gripping of the clamp part to an outside.

Articles, for example multi-ply fibrous structure-containing articles such as multi-ply sanitary tissue products, containing two or more fibrous structure plies, wherein at least one of the fibrous structure plies is embossed and is bonded to at least one other fibrous structure ply by a water-resistant bond such that void volume is created between the bonded fibrous structure plies.
