Abstract: A method of manufacturing a nozzle plate 2 is disclosed. The nozzle plate 2 has a plurality of nozzle openings 22 through each of which a droplet is adapted to be ejected. The method includes the steps of: preparing a processing substrate (silicon substrate 10) constituted from silicon as a main material, the processing substrate having two major surfaces; providing a supporting substrate 50 for supporting the processing substrate onto one major surface of the processing substrate 50; and forming the plurality of nozzle openings 22 on the other major surface of the processing substrate by subjecting the other major surface of the processing substrate to an etching process while the processing substrate is supported by the supporting substrate 50.

Abstract: Self-adhesive labels are formed by repetitively cutting linerless web material which is fed from a roll into and through a rotary knife cutter. The labels are then transported to and applied to articles. To improve cutting of the web and labeling, the web and or labels are contoured, e.g., they are made concave, in a plane transverse to the direction of flow path. To contour the web or labels, alternative endless belt arrangements are used, wherein the center line of the adhesive side of the web is adhered to a belt surface. Preferably, a one-piece belt having spaced apart and movable lengthwise portions is used. Different transport velocities are used for web fed to the cutter and for labels taken-away from the cutter. Cutter motion, and thus label length, in forming either linerless and lined labels, is controlled according to how printed indicia bar marks on the web are severed into portions; alternatively, according to whether or not the cut falls between two spaced apart printed indicia.

Abstract: A sign is formed from an adhesive-backed, vinyl sheet having a backing sheet. At least one graphic design or character is cut from the interior of the vinyl sheet. Tabs in the backing sheet extend between the edges of each character, the tabs maintaining the position of each graphic relative to the surrounding portion of the sheet. The sign is installed by adhering a portion of the graphics to the application surface, and then severing the tabs to free the vinyl graphics from the surrounding sheet. A device cuts the sign from the sheet and removes the waste material, reducing the labor required to produce the sign.

Abstract: This invention relates to a device for moistening envelope flaps, comprising a reservoir of liquid, means for pumping this liquid and, disposed transversely with respect to a direction of advance of the envelopes and inclined with respect to a horizontal plane for supporting these envelopes, means for spraying on the envelope flaps a part of the liquid pumped from the reservoir of liquid. This inclination of the spray means corresponds to the angle of inclination of the flaps of envelopes with folded down flaps.
