摘要： Known pneumatic pipe conveyor installations for fibres, particularly for textile fibre strands, comprise a conveyor pipe and a selectively operable feeder apparatus for feeding the fibres to the inlet opening of the conveyor pipe.For permitting the feeder apparatus to be automatically stopped in response to the formation of a fibre congestion adjacent the inlet opening of the conveyor pipe, there is provided a pressure-receiving surface (6) at least partially surrounding the inlet opening (5) of the conveyor pipe (2) and operatively connected to a switch (7) adapted to generate a stop signal for stopping operation of the feeder apparatus (3) in response to the pressure acting on the pressure-receiving surface (6) exceeding a predetermined value.The pneumatic pipe conveyor installation is useful for conveying fibre strands or slubbings in the textile industry.

摘要： Known apparatuses comprise a feed passage (4), a nozzle passage (5) extending therefrom in the feed direction (T), and a flow generator for generating a feed gas flow in the feed passage. The outlet portion of the nozzle passage (5) has provided therein a lateral opening (13) which permits the outflow of the gas stream.To be able to carry out pressure measurements in a measuring funnel with a known apparatus as well, the apparatus comprises a control (40) through which the lateral openings (13) can be closed. After the opening has been closed, pressure which can be measured with the aid of a pressure sensor (42) builds up in the tapered nozzle passage. The pressure measured corresponds to the thickness of the fiber sliver and can be used for controlling an upstream card.The apparatus is employed during the feed of card slivers.

摘要： The machine for making a non-woven material aerologically has a forming and conveying surface permeable to air, a dispersion chamber surmounting said surface and means, particularly vacuum means located under said forming and conveying surface of the non-woven material, which are capable not only of producing an air flow inside the dispersion chamber that allows the fibers inside the chamber to disperse and projects them onto the forming and conveying surface, but also create a vacuum in one zone—called the vacuum zone (9)—of the forming and conveying surface (1) of the non-woven material that extends under the dispersion chamber (2) and downstream from it, with the vacuum speed decreasing between the upstream and downstream parts of said zone (9).The wall downstream (4) from the vacuum chamber (2) is a plate, and the lower edge (12) of said downstream wall (4) delimits, along with the upper end (1a) of the forming and conveying surface of the non-woven material (1), a space for passage whose height is greater than the thickness of the non-woven material (13) coming out of the dispersion chamber (2).

摘要： So as to produce a condensed nonwoven, at least one first nonwoven is produced with the aid of a carding machine (1), said first nonwoven issued from the carding machine is directed to a rotating transfer element (20) by means of one first transport surface (S1), and said first nonwoven is transferred onto a second transport surface (S2) by means of said transfer element (20), the second transport surface (S2) being driven at a linear speed (V2) slower than the circumferential speed of the transfer element (20). In the transfer zone between the two transport surfaces (S1) and (S2), the first nonwoven is preferably kept against the surface of the transfer element (20) by means of suction. Application: production of heavy condensed nonwovens, especially having a weight of more than 80 g/m2.

摘要： In order to optimally control the air supply in a diverging gap between a card main cylinder and a doffer roll, an air guide plate with a predetermined spacing on the narrowest part between the air guide plate and the surface of the main cylinder and with an aperture angle is arranged close to the main cylinder so that a converging gap is provided between the air guide plate and the surface of the main cylinder. In this converging gap, a pressure head builds up in operation through the air conveyed from the surface of the main cylinder, which leads to an overflow over a nose of the air guide plate. This overflow helps the fleece, which is loosened from the main cylinder, to more easily reach the doffer surface. In order to control the quantity of overflowing air, the gap is to be determined by trial. The air passing through the gap may be taken up from a conduit shaped foot part, which can be connected to a vacuum source, for withdrawing particles of dirt which arrive in the conduit and, and to control the vacuum in the conduit. This pressure control may be effected through a throttle valve inserted between the conduit and a vacuum source. Subsequently, on the conduit, a series of card rods may be arranged in the direction of rotation of the main cylinder.

摘要： A device for producing fibrous non-woven structures. The device includes a first duct for conveying an air flow over the lateral surface of a carding cylinder to remove the fibers from the carding cylinder and to convey them to a mobile forming surface. It further includes a second duct joining with the first, wherein a flow of compressed air is passed through the second duct to create in the first duct the air flow utilized in removing the fibers. In addition, an adjusting member is provided, faced to said first duct, at the downstream, end of said second duct, to adjust its outlet section.
