An image forming apparatus including: a printer; a puncher configured to punch the sheet printed by the printer; a binder configured to perform a bookbinding process to form a bound product in which a binding member penetrates punch holes of sheets; a first detector configured to detect a first jam of a sheet in the binder; a second detector configured to detect a second jam of a sheet which occurs upstream of the binder; an annunciator configured to notify information; and a controller configured to cause the annunciator to notify first instruction information for instructing removal of a sheet and the binding member, when the first detector has detected the first jam; and cause the annunciator to notify second instruction information for instructing removal of the second jam when the second detector has detected the second jam and the first detector has not detected the first jam.

A cutting equipment trims strips of webs in movement by means of a stationary trimming blade and a rotating cylinder with a mobile trimming blade during transversal cuts and separation of basic sheets. The rotating cylinder includes a sector with suction openings connected to a vacuum source, which retains the strips by suction and drags the strips up to a collector of the trimmed strips. The cutting equipment cuts and separates transversal strips of two webs overlapped in adherence jointly to the cutting of the basic sheets. To this end, a perforating device perforates a row of holes on the first web adjacent to an edge of the sheets: a first web is positioned with the row of holes in front of the suction openings, while the strip of the second web is retained and dragged by suction through the holes of the first web up to the collector of the trimmed strips.

A method punches out a damper from a damper material set on a punching stage with use of a hollow punch so that the punched damper is positioned within a hollow inside of the punch while vibrating a member composing the punching stage on which the damper material is set at the high frequency. The damper material includes a viscoelastic body layer and the constraint layer laminated on the viscoelastic body layer and the viscoelastic body layer includes an attaching surface through which the damper material is detachably attached on the liner.

A rigid punch tool for cutting vents into plastic thermoformed containers. More specifically, a rigid punch tool comprising a holder with a plurality of slots; and a plurality of punches, each punch comprising a blade, a base, and attachment points, wherein, for each punch, the base of the punch fits into one of the plurality of slots in the holder, the base of the punch is wider than the blade of the punch, and bolts or pins fit in the attachment points to secure each punch to the holder.

A sheet punching device includes a punching unit, a cover member, an opening and closing sensor, a dust box, and a controller. The punching unit forms a punched hole in a sheet. The cover member can open and close the punching unit. The opening and closing sensor detects an open state of the cover member of the punching unit. The dust box is arranged in the punching unit and houses punch waste of the punched hole. The controller instructs continuation of a job of an image processing apparatus even if the opening of the cover member is detected by the opening and closing sensor without using the punching unit.

A sheet material (1) consisting of an mixture consisting essentially of: a) 10-50 percent by weight of random-oriented fibres, and; b) 90-50 percent by weight of a thermoplastic or thermoplastic elastomer; the weight percentages being based on the overall homogeneous mixture; and the sheet material having at room temperature a Shore D hardness of 40 to 85, preferably of 40 to 60, more preferably of 45 to 55. The sheet material (1) is used as a support in punching applications or as the top layer in punching belts (2).

An accumulator for an automatic sheet media punching and collating system includes a proximal end, having a shoulder, a distal end, and a moveable collating belt, disposed below the shoulder, extending from the proximal end to the distal end. The collating belt has an upwardly extending lower stop with an accumulating position opposite the shoulder, defining a drop region. The lower stop is configured to contact a lower edge of sheets of media sequentially received at the proximal end, whereby the sheets stop and accumulate in the drop region in a lift in a book order. The collating belt is selectively moveable to discharge the lift as a unit toward the distal end.
