An apparatus for manufacturing tow prepreg includes: a spreading roller which adjusts an incident angle of supplied fiber; and two or more coating rollers including a first roller and a second roller which rotate while having a gap between the first roller and the second roller, in which the fiber supplied from the spreading roller passes through the gap between the first roller and the second roller to be coated with resin. The incident angle of the fiber supplied for immersing the resin is adjusted to adjust tension applied to the fiber supplied to a coating roller, such that the quantity of the resin of the tow prepreg can be controlled more precisely.

The invention relates to a device for processing shear-sensitive coating compounds (100), with a transfer roller (1) and a doctor blade (2), in particular a comma doctor blade, which are spaced apart from one another to form a coating nip (3), the device further having an outlet nozzle (4) for dosing a coating compound (100), the outlet nozzle (4) facing a lower nip opening (6) of the coating nip (3) with its nozzle opening (5), wherein the device comprises a forced conveying system (7) via which a coating compound (100) is dosed into the coating nip (3), the transfer roller (1) and the doctor blade (2) being arranged next to each other, so that the coating nip (3) is permeable in the vertical direction (z), wherein the coating nip (3) is between 30 and 400 μm and the outlet nozzle (4) is an outlet of a rinsing chamber (8) arranged below the coating nip (3). A corresponding method is also described.

A wetout box apparatus is comprised of a breaker container, a first insert member, a second insert member, and a plurality of breaker bars. The breaker container is to store a volume of resin therein, the breaker container including a first slot and a second slot that allow a mat to enter and exit the breaker container, respectively. The first insert member is to be disposed within the breaker container on a first side of the breaker container. The second insert member is to be disposed within the breaker container on a second side of the breaker container. The plurality of breaker bars are coupled to the first and second insert members, the plurality of breaker bars forming a snaking path for the mat between the first slot and the second slot.

The invention relates to a device for processing shear-sensitive coating compounds (100), with a transfer roller (1) and a doctor blade (2), in particular a comma doctor blade, which are spaced apart from one another to form a coating nip (3), the device further having an outlet nozzle (4) for dosing a coating compound (100), the outlet nozzle (4) facing a lower nip opening (6) of the coating nip (3) with its nozzle opening (5), wherein the device comprises a forced conveying system (7) via which a coating compound (100) is dosed into the coating nip (3), the transfer roller (1) and the doctor blade (2) being arranged next to each other, so that the coating nip (3) is permeable in the vertical direction (z), wherein the coating nip (3) is between 30 and 400 m and the outlet nozzle (4) is an outlet of a rinsing chamber (8) arranged below the coating nip (3). A corresponding method is also described.

A manufacturing apparatus of a coating film product rolls a mixture coating material by a first roll and transfers the mixture coating material to a coated object in motion to thereby manufacture the coating film product. An arithmetic average roughness Ra on a roll surface of the first roll is higher than a value 0.05 times of a particle size d10 in which an integrated distribution of particle sizes of particles included in the mixture coating material is 10% and lower than a value 20 times a particle size d90 in which an integrated distribution is 90%.

A unit for spreading an adhesive onto a moving film, includes at least one pair of abutments (11) upon which is mounted a first pick-up roller (12) for collecting a quantity of adhesive from a collection zone (13), a second roller (14) that rotates in contact with the first roller (12), intended to receive the quantity of adhesive, and a third roller (15) that rotates in contact with the second roller (14), wherein the abutments include at least one fixed portion (19) and one moving portion (20, 21) that can be firmly connected to the fixed portion, the moving portion being configured: to house a tank (17) in which the adhesive collection zone is found, or to house an additional fourth roller (18) positioned at a given distance from the first roller, the collection zone being located in the upper space between the first and the fourth roller (12, 18).

The invention relates to a device for processing shear-sensitive coating compounds, with a transfer roller and a doctor blade, in particular a comma doctor blade, which are spaced apart from one another to form a coating nip, the device further having an outlet nozzle for dosing a coating compound, the outlet nozzle facing a lower nip opening of the coating nip with its nozzle opening, wherein the device comprises a forced conveying system via which a coating compound is dosed into the coating nip, the transfer roller and the doctor blade being arranged next to each other, so that the coating nip is permeable in the vertical direction (z), wherein the coating nip is between 30 and 400 m and the outlet nozzle is an outlet of a rinsing chamber arranged below the coating nip. A corresponding method is also described.
