The invention discloses a drum screen. The drum screen comprises a plurality of screen plates and a plurality of winding-preventing battens (2), wherein the winding-preventing battens (2) are arranged at intervals along the circumferential direction of the drum screen and are arranged on the outer wall face of the screen plate. The winding-preventing battens can prolong the distances of a strip-shaped material passing through screen holes back and forth and the inter-hole connecting bars of hooks, thereby improving the probability of successful back-and-forth passing and winding and reducing the phenomena of winding and knotting.

The application relates to a preparation process of nickel-plated carbon fiber felt, which relates to the field of fiber products. The felting process includes the following steps: fiber pretreatment: dispersing the fibers; felting forming: felting the dispersed fibers, Then the formed fibers are sizing, and the glue is cured to obtain a felt; the fiber pretreatment includes the following steps: mixing the fibers with water and then stirring and dispersing to obtain a pretreatment slurry, and then performing a second step on the pretreatment slurry Deflagging to obtain dispersed fiber slurry. The application can effectively improve the quality of the fiber felt.

The invention discloses a yarn conveying device of a small double-face circular machine. The yarn conveying device comprises a body, one side of the body is provided with yarn conveying wheels, each yarn conveying wheel is provided with a plurality of yarn guide grooves, the bottom face of each yarn guide groove is a big-end-up inclined face, and a yarn combing wheel is arranged above the yarn guide grooves and is arranged on the body through a spring. The yarn combing wheel comprises more than two yarn combing grooves, the bottom face of each yarn combing groove is a big-end-up inclined face, the yarn combing wheel further comprises two balls, a spring piece is arranged between the balls, and a clamping piece is arranged between the yarn combing wheel and the balls and is provided with clamping grooves with different widths. According to the yarn conveying device, weaving quality is improved, yarn can be combed, and knotted yarn ends are prevented from entering weaving components.

The invention relates to a silk reeling method and a silk reeling device, in particular to a band friction method and a band friction device for replacing a silk sheath. The method and the device mainly solve the technical problems that a wet raw silk gathering method during silk reeling production in the prior art forms a silk sheath structure by adopting a manual mode, and gathers wet raw silk through a silk sheath effect, and the quality of the raw silk is influenced, operation is complicated, and labor productivity is low due to the nonuniformity of the silk sheath structure between threads brought by the method, or solve the technical problem that gathering is nonuniform due to periodical change of the speed when back-and-forth friction is conducted by adopting reciprocating movement. According to the method and the device, upper and lower layers of driving bands which can be used for replacing silk sheath gathering cocoon silk and move reversely are wound with the wet raw silk; silk pressing guide rolls are arranged between the driving bands; a winding movement direction of the wet raw silk is perpendicular to movement directions of the driving bands relative to the raw silk; friction is generated between the wet raw silk and the driving bands; and tiny sections on the surface of the cocoon silk can be removed after rotation and kneading.
