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.

A binding device includes a first pressing member that presses a recording-medium stack from one surface side of the recording-medium stack, a second pressing member disposed at a position opposed to the first pressing member to press the recording-medium stack from the other surface side of the recording-medium stack, and a reduction part provided in at least one pressing member of the first pressing member and the second pressing member to reduce creases in recording media of the recording-medium stack in a binding operation when a number of the recording media in the recording-medium stack is smaller than a maximum number of recording media to be bound by the first pressing member and the second pressing member.

A system including a panel having a panel opening and a coupling device coupled to the panel. The coupling device includes a coupling device opening and a flange positioned adjacent to the coupling device opening. The coupling device opening at least partially overlaps with the panel opening, and the flange is elastically deflectable to allow a binding mechanism to pass the flange and into or out of the coupling device opening.

A machine for applying support members to opposing sides of opposing edges of a sheet material includes a support tab applicator assembly that applies a first portion of a support tab along a longitudinal edge of a first side of the sheet material, a support tab finisher assembly that applies a second portion of the support tab disposed opposite the first portion to a second side of the sheet material disposed opposite the first side, and a hole punch assembly that cuts a hole through the sheet material. The machine also may include a strengthening film applicator assembly that applies a strengthening film along a longitudinal length of the first side of the sheet material and/or across the support tab.

A device for providing attachment points for a folder has a layer of material with an inside surface and an outside surface. The inside surface folds onto itself to form a doubled layer having a folded edge and a cut out section. A supporting segment at or near the folded edge closes the cut out section into an aperture for receiving a closing mechanism of a binder. The device is adhered to the inside of a folder at the folder openings arranged to receive the binder's closing mechanism. When the reinforced folded folder is mounted into a binder, both sides of the folded folder press against the attachment device to contain the attachment device in the folder, and the supporting segment presses against the closing mechanism to contain the folder in the binder.

The present technology relates generally to devices and methods for preserving the integrity of folders that are placed into ringed binders or notebooks, preferably folders that are made of paper or other like material, and which are used for example for the transport and storage of papers by students or other types of users.

A system including a panel having a panel opening and a coupling device coupled to the panel. The coupling device includes a coupling device opening and a flange positioned adjacent to the coupling device opening. The coupling device opening at least partially overlaps with the panel opening, and the flange is elastically deflectable to allow a binding mechanism to pass the flange and into or out of the coupling device opening.

A recording-medium binding device includes a first tooth row and a second tooth row. The first tooth row and the second tooth row to be engaged with the first tooth row cooperate with each other to pinch a recording medium batch. The first tooth row and the second tooth row include at least one first region and at least one second region adjacent to the at least one first region. When the first tooth row and the second tooth row are engaged with each other, teeth of the first tooth row and teeth of the second tooth row overlap one another in a tooth height direction by a first engagement overlapping amount in the at least one first region and by a second engagement overlapping amount in the at least one second region. The second engagement overlapping amount is larger than the first engagement overlapping amount.

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.

A binding device includes a first pressing member that presses a recording-medium stack from one surface side of the recording-medium stack, a second pressing member disposed at a position opposed to the first pressing member to press the recording-medium stack from the other surface side of the recording-medium stack, and a reduction part provided in at least one pressing member of the first pressing member and the second pressing member to reduce creases in recording media of the recording-medium stack in a binding operation when a number of the recording media in the recording-medium stack is smaller than a maximum number of recording media to be bound by the first pressing member and the second pressing member.
