In a fleece layer of the carriage cross-lapper type, the laying carriage conveyor belt ( 14 ) wraps around the first laying roller ( 12 ), the upper and lower strands ( 14 o, 14 u) of the belt being parallel to each other as they proceed from the first laying roller ( 12 ). An endless cover belt ( 23 ), which travels around in the laying carriage ( 5 ), wraps around the second laying roller ( 13 ), the cover belt having upper and lower strands ( 23 o, 23 u), which are parallel to each other as they proceed from the second laying roller ( 13 ) in the direction opposite that of the laying carriage conveyor belt ( 14 ). The mutual distances between the web entrance ( 8, 9 ), the upper carriage ( 4 ), the laying carriage ( 5 ), and the output conveyor belt ( 2 ) perpendicular to the transport directions of same are so small that the card web ( 11 ) to be laid is enclosed in a sandwich-like manner between the adjacent strands of the web entrance conveyor belt ( 6 ), of the upper carriage conveyor belt ( 20 ), and of the laying carriage conveyor belt ( 14 ), where the laid fleece on the output conveyor belt ( 2 ) is contacted by the laying carriage conveyor belt ( 14 ) and by the cover belt ( 23 ).

The invention relates to an air flow net forming machine, which belongs to the technical field of textile machinery and comprises a machine frame, a large pin roll, a small pin roll, an output curtain and a draft mechanism, wherein the machine frame is provided with a cotton mixing box, an air inlet box and a cotton inlet passage, the large pin roll and the small pin roll are arranged on the machine frame, the output curtain is matched and arranged on the machine frame, and the draft mechanism is arranged at the bottom of the machine frame. The air flow net forming machine is characterized byalso comprising a dust cage and a dust cage driving mechanism, wherein the dust cage is arranged on the machine frame and corresponds to a position under the cotton inlet passage, the dust cage driving mechanism is arranged at the lower part of the machine frame and is in transmission connection with the dust cage, the output curtain corresponds to the side part in the length direction of the dust cage, and the draft mechanism corresponds to the bottom in the length direction of the dust cage. The air flow net forming machine has the advantages that the side draft in the prior art is changed into bottom air draft, so the non-woven fiber cotton layer reaching the output curtain is more uniform to ensure the uniformity of the gram weight of the non-woven products. Because of the adoption ofthe bottom draft, the output resistance of a cotton net can be reduced, the net forming speed is favorably accelerated, and in addition, a blockage phenomenon of the non-woven fiber cotton in the cotton output passage can be avoided.

The invention relates to a net forming mechanism of a gas flow type net forming machine, belonging to the technical field of non-weaving machinery. The gas flow type net forming machine comprises a frame, large and small taker-in rollers, a cotton net output mechanism and an air draft mechanism, wherein the frame is provided with a cotton blending box, an inlet duct and a cotton inflow channel. The net forming mechanism comprises a dust cage device and a dust cage driving device, wherein the dust cage device comprises a dust cage drum body, a pair of air channel partition mechanisms and a gear shaft; air suction holes are distributed on the dust cage drum body, dust cage rings are fixed at two ends of the dust cage drum body, roller wheel grooves are opened on the inner walls of the dust cage rings so as to form gear rings, gears are fixed at two ends of the gear shaft, and the gears are meshed with the gear rings; and the dust cage driving device is arranged on the frame; the cotton net output mechanism corresponds to one side of the dust cage drum body; and the air draft mechanism corresponds to the bottom of the dust cage drum body. The net forming mechanism has the advantages that nonwoven fiber cotton is conveyed to the cotton net output mechanism at a uniform thickness; and the net forming speed is increased, the stagnation of the nonwoven fiber in the cotton inflow channel is avoided and the interference of the air draft mechanism on the cotton net output mechanism is not generated.

In an apparatus in spinning preparation for separating foreign objects at conveying equipment for fibre material, at least one separation device is associated with the conveying equipment. The separation device comprises an arrangement for producing a blast of air that flows in the direction onto the conveying equipment and generates an air flow that detaches the foreign objects from the conveyed fibres and carries them away. The arrangement comprises a plurality of blast nozzles arranged across the width of the conveying equipment and connected to a compressed air pipe and to valves. To reduce the proportion of good fibres in the waste in a simple manner, and to allow a more selective action of the blast air current, a bar member for mounting the blast nozzles is present and the nozzles are integrated in the bar member.

A vibratory separator including a housing having a drilling material inlet and at least one basket, at least one screen assembly configured to be disposed in the at least one basket, an actuator connected to the at least one basket, wherein the actuator provides vibratory motion to the at least one basket, a sump configured to receive drilling material that passes through the at least one screen assembly, and at least one spray nozzle for cleaning the vibratory separator is disclosed. A method for cleaning a vibratory separator including providing instructions to a programmable logic controller to activate at least one spray nozzle disposed on the vibratory separator is also disclosed. A method of retrofitting a vibratory separator including installing at least one spray nozzle in a vibratory separator, installing a programmable logic controller on the vibratory separator, and providing instructions to the programmable logic controller to activate at least one spray nozzle disposed on the vibratory separator is disclosed.

The feed device for supplying individualized fibers or fiber flocks to a transport device, which serves to transport the formed fleece or fiber flock mat onward, includes a plurality of feed segments arranged horizontally next to each other and a plurality of individually actuatable feed rollers, wherein a separate feed roller is assigned to each feed segment. In addition, at least one driven opening cylinder, which cooperates with each feed roller, is also provided.
