The present specification relates to a dough line for processing dough, specifically sheeted dough, having a conveyor, for conveying the dough, a sensor, for detecting the beginning of a dough piece at a detection point in the dough line, a controllable flour sifter, arranged above the conveyor, for depositing flour on the conveyor or on dough on the conveyor, a controller, for controlling the amount of flour deposited by the flour sifter based on the sensor signal, wherein the controller is configured for disabling the flour sifter when there is no dough piece on or to be placed on the conveyor at the location of the flour sifter, enabling the flour sifter to deposit a first amount of flour per amount of displacement of the conveyor when there is a dough piece on or to be placed on the conveyor at the location of the flour sifter.

A fluid application device having a contact nozzle assembly with a fluidic oscillator is provided. The fluid application device includes an applicator head and a nozzle assembly. The nozzle assembly includes a first conduit configured to receive a first fluid from the applicator head, a second conduit configured to receive a second fluid from the applicator head and an application conduit including a receptacle and first and second branches. The receptacle is fluidically connected with the first conduit and configured to receive the first fluid. The first and second branches are fluidically connected to the second conduit and receptacle and are configured to receive the second fluid. The nozzle assembly further includes an orifice fluidically connected to the application conduit and configured to discharge the first fluid for application onto a strand of material, and a guide slot extending from the orifice and configured to receive the strand of material.

The invention relates, inter alia, to a device (10) for applying a plurality of threads (17) of a fluid, such as adhesive or lotion, to a moving web-like substrate (11), having a plurality of outlet openings (15a, 15b, 15c, 15d, 15e) for the threads of fluid (17, 17a, 17b, 17c), wherein each outlet opening is disposed between a pair of flow openings (16a, 16b, 16c, 16d, 16e), through which a flow fluid (21), in particular compressed air, flows in order to achieve thread oscillation. The special feature consists, inter alia, in that the outlet openings are disposed along a curved path (22, 22).

An automatic dispensing device for wallboard joint taping is provided, including a body for holding a supply of viscous material and having a rear end and an opposite front end, a spool assembly disposed on the body and configured for supporting a spool of tape; at least one drive roller positioned at the front end and receiving an end of the spool of tape. Certain embodiments include an adhesive application assembly connected to the drive roller and mounted in operational relationship to the front end for dispensing a measured amount of adhesive upon an upper surface of the tape upon rotation of the at least one drive roll. In such embodiments, the body may be configured for holding sufficient adhesive to cover tape advanced by at least 200 rotations of the at least one drive roller.

A method for applying coating material to a moving substrate such as a glass mat web in shingle manufacturing includes conveying the web through a narrow channel and ejecting at least one coating material onto at least one surface of the web as it is conveyed through the channel. In a preferred embodiment, multiple coating materials may be applied to one surface of the web and multiple coating materials may be applied to the other surface of the web. The coating materials may be molten asphalt or other coating materials. The pressure of the coating material is controlled as a function of the line speed of the moving substrate to ensure consistently thick coatings at various speeds, including relatively high speeds, of the web. An apparatus in the form of a slot die is disclosed for carrying out the method of the invention.

A system for the functionalization of polyolefin fiber includes a reactor chamber, a fiber pulley system, and a precursor sprinkler system. The reactor chamber defines an interior reactor space and a plurality of fiber inlet/outlet pairs positioned at opposite ends of respective fiber processing axes. The fiber pulley system is arranged to direct polyolefin fiber through the plurality of fiber inlet/outlet pairs, along a fiber processing path comprising the respective fiber processing axes. The precursor sprinkler system is operable to aerosolize a precursor solution and contact the aerosolized precursor solution with the polyolefin fiber. A method for functionalizing polyolefin fiber includes aerosolizing the precursor solution to form an aerosolized precursor solution, passing polyolefin fiber along the fiber pulley system into the reactor chamber, contacting the polyolefin fiber with the aerosolized precursor solution, and passing functionalized polyolefin fiber out of the interior reactor space of the reactor chamber.

According to one embodiment, a system for manufacturing a polymethyl methacrylate (PMMA) prepreg includes a mechanism for continuously moving a fabric or mat and a resin application component that applies a methyl methacrylate (MMA) resin to the fabric or mat. The system also includes a press mechanism that presses the fabric or mat during the continuous movement subsequent to the application of the MMA resin to ensure that the MMA resin fully saturates the fabric or mat. The system further includes a curing oven through which the fabric or mat is continuously moved. The curing oven is maintained at a temperature of between 40 C. and 100 C. to polymerize the MMA resin and thereby form PMMA so that upon exiting the curing oven, the fabric or mat is fully impregnated with PMMA.
