A creasing device is provided that includes a counter-rotating male drum and female drum. The male drum carries a conventional creasing ring with a central rib flanked by shoulders. The female drum comprises a central channel aligned with the creasing rib on the male drum; and a pair of projecting lateral ribs on each side of the central channel that are aligned with the shoulders on the male drum. The lateral ribs press a sheet of the card or paper stock against the shoulders of the creasing ring to better define the edges of the crease and to reduce the tendency of a printed coating on the stock to crack during subsequent folding. The pair of lateral ribs may be provided by a pair of inserts. Alternatively, both ribs and the central channel may be provided by a single insert.

The present invention relates to a device for treating substrates which device is modular and versatile in use. The device for treating substrates comprises a feeder and one or more first sub-structure modules which each comprise a pressure cylinder with devices for fixing a lift and a sheet-conveying device and one or more second sub-structure modules which respectively have a transport cylinder with openings formed on the cover surface thereof, and having devices for fixing a lift and a sheet conveying device. All of the first or second sub-structure modules have the same intersection point for connecting the sub-structure modules on one of the inlet and the exit side and they all can be equipped with an attachment module.

A converting machine is used to convert sheet material into packaging templates for assembly into boxes or other packaging. The converting machine includes a converting assembly that performs transverse conversion functions and longitudinal conversion functions on the sheet material to create the packaging templates. A fanfold crease sensing mechanism detects the presence and location of fanfold creases in the sheet material. Based on the location of the fanfold creases, the fanfold creases are either cut out of the sheet material, or the sheet material is cut to adjust the position of the fanfold crease in a packaging template.

According to an embodiment, a sheet folding apparatus comprises a first roller, a second roller configured to be energized to the first roller, form a nip section together with the first roller, fold a sheet in half together with the first roller through the nip section and convey the sheet folded in half together with the first roller and a pressing force adjusting mechanism configured to be capable of increasing and decreasing a pressing force generated at the nip section. The pressing force adjusting mechanism causes a pressing force in a state of being conveying the sheet folded in half to be lower than that in a state of being folding the sheet in half.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank—including providing air vents to allow trapped air to escape during the pre-sealing process—to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

The present invention relates to a container, particularly a cup, with a base and a first sidewall, wherein the first sidewall comprises at least a first, at least partially circumferential shaping directed inwardly and/or outwardly. The container may also include a second sidewall attached to the shaping of the first sidewall at a connection point thereby providing an air gap between the first sidewall and second sidewall. The shaping of the first sidewall may include a tip to which the second sidewall is sealed or glued.

A sheet processing apparatus includes: first to third pairs of conveying members; and a bifurcating claw that moves to a first guiding position for guiding the sheet to the second pair of conveying members, a second guiding position for guiding a deflected portion of the sheet to the third pair of conveying members, and a third guiding position for guiding a leading end of the sheet to the third pair of conveying members. The second pair of conveying members is rotated backward in a state in which the sheet is held by the first pair of conveying members and the second pair of conveying members, to guide the deflected portion to the third pair of conveying members and cause the deflected portion to be folded by the third pair of conveying members.

The invention provides a whetstone type of scoring device for production of gypsum boards which can accurately and stably form a groove of a constant depth on a sheet of paper for gypsum board liner, and which can prevent wear of a rotary blade and a backing block. The scoring device (11) for a gypsum board production machine (10) has the rotary blade (24) and the backing block (30). The sheet (3) travels under tension over the block (30), which abuts against the lower surface of the sheet. The block has an opening (32) immediately under the blade. The lower surface of the sheet is released downward by the opening. The sheet is ground by a blade edge (24a) while being slightly bent downward within a range of the opening (within an intimate contact area of an angle β).
