A sheet postprocessing device includes a saddle binding device configured to stack a plurality of recording sheets on a table, abut leading edges of the respective recording sheets against a leading edge cursor, thus to align the leading edges with each other, and bind the center of the recording sheets and fold the recording sheets, and a first pressing member supported so as to pivot in a direction toward and away from the table. The first pressing member is made to pivot toward the table by self-weight thereof, allows the leading edge of the recording sheet delivered to the table to pass toward the leading edge cursor, and presses a portion of the recording sheet in a proximity of the leading edge, at a position upstream of the leading edge cursor, in a delivery direction of the recording sheet.

A method of stacking a plurality of absorbent sheet products is provided. In an embodiment, the method includes folding an absorbent sheet inwardly along a first folding line to form a first inner panel, folding the absorbent sheet inwardly along a second folding line, substantially parallel to the first folding line, to form a second inner panel, folding the absorbent sheet along a third folding line substantially perpendicular to the first and the second folding lines to form a first outer panel and a second outer panel, sandwiching the first and the second inner panels therebetween to obtain one of the absorbent sheet products, and inserting at least a section of at least one of the first and the second outer panels of each one of the absorbent sheet products between the first and the second outer panels of an adjacent one of absorbent sheet products of the stack.

The present disclosure provides method, computing device readable medium, and devices for dental appliances formed with folded material components. An example of a method of forming a dental appliance, includes forming a shell having a number of tooth apertures configured to receive and reposition a number of teeth of a patient along one jaw of a patient, the shell having a number of specialized components and wherein the number of specialized components are formed from folding multiple sections of the first sheet of material over each other.

A sheet post-processing apparatus (1) includes a processing tray (5), a sheet discharge port (7), a conveyance rollers pair (4), lower and upper discharge rollers (81), (82) and a discharge tray (9). When the sheet having a folded portion is stacked on the processing tray (5) with the folded portion downward, a controller rotates the lower and upper discharge rollers (81), (82) to advance the folded portion to the sheet discharge port (7), stops the lower discharge roller (81) before the folded portion passes the sheet discharge port (7), rotates the conveyance rollers pair (4) and the upper discharge roller (82) so as to convey the rear half portion to the downstream side until the sheet passes the conveyance rollers pair (4) and to form a deflection on the sheet, rotates the lower and upper conveyance rollers (81), (82) and then to stack the sheet on the processing tray (5).

The sheet discharge device includes: a sheet discharge part; a sheet discharge tray having a tray upper surface and a rear wall portion; a fullness detection sensor for detecting that a height of a stack surface of folded sheets; and a first sheet presser member and a second sheet presser member for pressing a rear end side and a fore end side in a discharge direction, of the folded sheet. In a first pressing position in which the first sheet presser member extends from above the detection sensor to below the detection region, and is brought into contact with the folded sheet of a minimum size stacked on the tray upper surface. When a stack number of the folded sheets has exceeded a specified number, the first sheet presser member is retracted upward from the first pressing position by the rise of the stack surface.

The present invention includes a reclosable bag having first and second walls and an open top defined by first and second elongate flexible fastener strips attached to the first and second walls, respectively, adjacent the top of the walls. One of the fastener strips has a profile portion forming at least one groove and the other fastener strip has a profile portion forming at least one rib with a portion of each rib received and retained in one of said grooves when the bag top is closed. Each of the fastener strips has a base connected to the respective wall, and each of the strips has an upper edge adjacent the upper edge of the other strip. Third and fourth fastener strips are located within the bag walls parallel to and below the first and second fastener strips. The third and fourth fattener strips have one or more pairs of ribs and grooves. An inverted slider is mounted on the second and third fastener strips within the bag and is movable in one direction longitudinally of the third and fourth fastener strips to progressively separate the one or more rib from the one or more grooves to open the bag: the slider is also being movable in the opposite direction to progressively return the one or more rib portion to a retained condition in the one or more groove to close the bag. A plow extends from the slider to the exterior of said bag above the top of said bag. The plow has a finger tab extending affixed thereto at the distal end thereof. The plow is constructed and arranged to selectively separate said first and second rib and groove and to move said slider within said bag to separate said third and fourth rib and groove when said plow is moved longitudinally along said fastener strips from a first end of said strips to a second end of said strips. The plow is also constructed and arranged to slide said slider longitudinally along the third and fourth fastener strips from said second end and back to said first end so as to interlock said third and fourth ribs and groves and seal said third and fourth fastener strips within said bag. Alternatively, the Claim 1 first and second fastener strips may be selectively sealed by pressing the outer walls of said bag together proximate said first and second fastener strips so as to longitudinally interlock said first and second fastener strips together.
