According to one embodiment, a system for manufacturing a fully impregnated thermoplastic prepreg includes a mechanism for moving a fabric or mat and a drying mechanism that removes residual moisture from at least one surface of the fabric or mat. The system also includes a resin application mechanism that applies a reactive resin to the fabric or mat and a press mechanism that presses the coated fabric or mat to ensure that the resin fully saturates the fabric or mat. The system further includes a curing oven through which the coated fabric or mat is moved to polymerize the resin and thereby form a thermoplastic polymer so that upon exiting the oven, the fabric or mat is fully impregnated with the thermoplastic polymer. During at least a portion of the process, humidity in the vicinity of the coated fabric or mat is maintained at substantially zero.

The present invention provides a draw device. The draw device includes a draw head, a draw opening, a draw tube, at least one pressure hole, and at least one flow guiding channel. The at least one flow guiding channel is respectively arranged corresponding to the at least one pressure hole. Each flow guiding channel communicates with the corresponding pressure hole to take out a drawn liquid inside the pressure hole.

A method for applying a polymeric composition discharged in a fluid form from a slot die applicator to a substrate, the slot die applicator including a slot opening, a first lip, and a second lip, the slot opening located between the first lip and the second lip; and the substrate having a first surface disposed opposite of a second surface and an unconstrained caliper, Hs, the method comprising the steps of positioning the substrate carrier adjacent the slot die applicator to define a minimum distance, Hg, between the substrate carrier and the first lip and the second lip that is substantially the same or less than the unconstrained caliper, Hs, of the substrate. The polymeric composition has Tensile Strength at Yield of from about 0.5 MPa to about 10 MPa, as measured according to the Tensile Strength Test Method described herein. The method can be used to make absorbent articles having a substrate with an application pattern comprises continuous and/or discrete pattern elements having a dimension in machine direction of less than 10 mm.

A nozzle apparatus may comprise a nozzle body having a nozzle tip with a discharge port for spraying a treatment fluid onto a substrate; a nozzle moving member for moving the nozzle body relative to the substrate; a rotating member for rotating the nozzle body or the nozzle tip so that a treatment fluid is sprayed onto the substrate during rotation; and a control unit configured to control an operation of the nozzle moving member and the rotating member.

A method of coating an active material for a secondary battery according to one embodiment of the present disclosure is a method of coating an active material on an electrode current collector of a secondary battery, the method comprising the steps of: disposing a guide member on each of the left and right sides based on a moving direction of the electrode current collector, and coating the active material onto the electrode current collector between the two guide members.

Disclosed is a coating apparatus for producing an electrode, which has a reduced defect rate in the coating process. The coating apparatus includes a die unit having an inlet through which the electrode slurry is introduced and an inner space for accommodating the introduced electrode slurry; a shim unit mounted in the die unit and configured to form an outlet together with the die unit so that the electrode slurry is discharged therethrough; and a cover member configured to surround an outer surface of the die unit and the shim unit so that the electrode slurry is not leaked at the outer surface, except for the outlet.

Method of producing an image display device in which an image display member and light-transmitting cover member having principal surface portion and circumferential edge portion on which a light-shielding layer is formed with a step portion formed between the principal surface portion and the circumferential edge portion are laminated through light-transmitting resin layer formed from a liquid optical resin composition so a light-shielding layer formed surface of the light-transmitting cover member is arranged to face the image display member, when a resin dispenser is moved from one end of the light-shielding layer formed surface of the light-transmitting cover member toward the other end applying the liquid optical resin composition to the light-shielding layer formed surface of the light-transmitting cover member, the application amount of optical resin composition is changed on the principal surface portion of the light-shielding layer formed surface of the light-transmitting cover member and on the light-shielding layer.
