An absorbent body in which a larger amount of a granular absorbent substance penetrates into the inside of a fiber sheet is produced. A fiber sheet having napped one main surface is supplied to a conveying device and conveyed while the other main surface of the fiber sheet is being sucked through a conveyance surface. A granular absorbent substance is sprayed onto the napped one main surface of the fiber sheet to cause the substance to penetrate into the inside of the fiber sheet in a suction section. A pressure difference increasing device is provided that faces the one main surface of the fiber sheet sprayed with the absorbent substance and being conveyed in the suction section, and that suppresses air from flowing through the fiber sheet inward from the conveyance surface to increase the pressure difference between the conveyance surface side and the opposite side of the fiber sheet.

The invention relates to an atomizer unit of a minimal quantity lubricant system (2) for a cooling and/or lubricating function of a cutting-machining process. The atomizer unit (3) has a chamber assembly (8) with an injection chamber (9) and an atomizer chamber (10), wherein the injection chamber (9) is connected to the atomizer chamber (10) by a nozzle (11), and the atomizer unit (3) has at least one first feed channel (12) for feeding a first compressed air flow (13) into the injection chamber (9), at least one second feed channel (14) for feeding a second compressed air flow (15) into the atomizer chamber (10), and an injection valve (16) for injecting a coolant and/or lubricant (4) into the first compressed air flow (13) in the injection region (17) of the injection chamber (9). The atomizer unit (3) is designed such that the first compressed air flow (13) flows from the injection chamber (9) into the atomizer chamber (10) through the nozzle (11), is atomized in the atomizer chamber by the nozzle (11), is combined with the second compressed air flow (15) in the atomizer chamber (10) in order to form a transport flow (18) for transporting the injected coolant and/or lubricant (4), and can be conducted to the machining location (7). The atomizer unit (3) has a heater (20) which heats the coolant and/or lubricant (4), the first compressed air flow (13), the second compressed air flow (15), and/or the transport flow (18).

A spray applicator (1) for spraying a fluid onto a web (W) of material has a first group of spray nozzles (10A) arranged along a first axis (FA) and a second group of spray nozzles (11A) arranged along a second axis (SA). The first (FA) and second (SA) spray nozzle axes are arranged on the same side of a plane in which the web (W) is run. Each spray nozzle (10A, 11A) has an elongated spray opening configured to spray fluid in a direction towards the web (W). The first spray nozzle opening of the first group of spray ozzles (10A) has an inclination angle which differs from the second nozzle opening inclination angle of the second group of spray nozzles (11A).

A sprayer control system includes a plurality of smart nozzles each having at least one control valve with a valve operator, an electronic control unit for the valve operator, and one or more spray nozzles. The at least one control valve and the ECU control a flow rate of liquid agricultural product through the nozzles. A duty cycle modulator is in communication with the ECU and generates an applied duty cycle for the at least one control valve. The duty cycle modulator includes a specified duty cycle input having a specified duty cycle and a pressure monitor associated with the at least one control valve. A pressure comparator compares the valve pressure determined with the pressure monitor with a system pressure and generates a pressure error. An applied duty cycle generator generates the applied duty cycle based on the specified duty cycle modified by the pressure error.
