In a device for opening pressed fiber bales material, using at least one milling roller (3,4) acting on the bale surface (20) of the fiber bales, and one pressure roller (18) arranged before and behind the milling roller, respectively, in the moving direction thereof and parallel thereto. A suction hood (21) is arranged above the milling roller (3,4) for sucking off the reduced fibers in an air flow. And air-guide channel (2), provided by a plurality of air-guide sheets (22,26), is arranged between the pressure roller (18) and the milling roller (3,4), extending over the whole length of the milling roller (3,4) and in parallel to the milling and pressure rollers (3,4,18).
摘要:
Opening and blending apparatus for removing fiber from a row of bales has spaced parallel drums carrying disks and the like illustrated in spaced overlapping relation and being driven in opposite directions at different speeds. Spaced grid bar members may be offset in a gap between the drums and terminate in free ends. The grid rods may extend continuously from lateral fixation bars and may be connected by central elements.

In an opening device for opening pressed fibre bales, e.g. cotton and viscose fibre bales and the like, by means of a reduction device, e.g. a milling device, being translationally movable over the surface of a bale or a row of bales, the reduction device having at least one milling roll with pressure rolls (17, 18) being disposed axially parallel on both sides of the reduction device, opener discs (14), provided on the milling rolls (3,4) meshing with a grate (10), the grate bars (11) of which lie between the opener discs (14) that engage the bale surface, and with a metal detector device, it is provided that the grate bars (11) are extended towards the pressure rolls (17, 18) to the immediate vicinity of the pressure rolls (17,18), and that the metal detector device is formed by the grate bars (11) and said pressure rolls (17, 18), the grate bars (11) forming a first contact surface and the pressure rolls (17, 18) forming a second contact surface.
摘要:
An apparatus for reducing pressed fiber bales arranged in a row is disclosed which facilitates removal of fibers from the upper surface of the bales adjacent a stationary member (28). Transversely extending rollers (18, 19) parallel to milling rollers (4, 5) are provided with blocking means (25, 26). These blocking means may be actuated to prevent rotation of rollers (18, 19). As rollers (18, 19) are carried by housing (2) so as to extend slightly beyond the housing in the direction of travel (16). Upon reaching stationary member (28), blocking means prevents rotation of roller (19). The teeth of roller (19) act as a rake to remove fibers from bale (24a) adjacent stationary member (28) as reducing means (1) starts its travel in the return direction. In this manner, the fibers from the entire upper surface of bale (24) are more totally and uniformly removed.

Centrifugal separator drum (FIG. 1) for the clarification and separation of liquids, having one or more paring systems 12, 13 for the removal of the clarified or separated liquids, a stationary inlet tube 11 which communicates with a smooth, cylindrical inlet chamber 18, which rotates with the drum and is affixed to the latter, via an opening that is slightly larger than the inlet tube. Outlets ports 20 lead out of the inlet chamber into a forechamber 21 which communicates on the one hand with an annular chamber 24 situated ahead of the inlet chamber and on the other hand with the riser passages 23 of the plate insert 4. According to the invention, the inlet chamber 18 is sealed off from the external atmosphere; the distance from the outlet of the inlet tube 11 to the entry of the outlet ports 20 amounts to at least thrice the inside diameter of the inlet chamber, and the total cross section of the outlet ports is smaller than the cross section of the inlet chamber and larger than the cross section of the inlet tube. The outlet ports have one or more chokes. Thereby, during operation, an increased liquid pressure develops in the lower part of the inlet chamber ahead of the outlet ports and the inlet chamber can be kept largely filled with liquid.
摘要:
A headrest assembly used in a motor-vehicle seat formed with an upwardly open recess has a pair of complementary housing shells having mating annular edges that meet and are joined together substantially on an upright plane to form a cavity. Each shell is formed with a pair of seat halves open at the plane and forming with the seat halves of the other shell a pair of seats aligned along a horizontal axis and lying on the plane. The joined shells are set and secured in the recess of the seat. Respective pivot bodies in the cavity engaged in the seats are pivotal therein about the axis between upright and horizontal positions. Respective support rods extend radially from the pivot bodies out of the cavity and a headrest is fixed on the support rods outside the cavity.

An arrangement for adjusting the distribution of pressure on a support plate in a backrest of a vehicle seat for vertebral support, wherein a pressure-distribution element which is adjustable in respect of height and which is in the form of a rolling carriage assembly is disposed between the support plate and a pressure plate.
摘要:
A device and method for pneumatically feeding fiber flocks into a plurality of feeding chutes of fiber processing machines connected with at least one distributing line, the feeding being effected through a fiber and transport air flow, characterized in that the distributing line is a formed by a closed circular line (4) into which a first transport line section (6) opens for feeding in fiber flocks, and that, at the end of the first transport line section (6), the fiber and transport air flow may be switched selectively into the one or the other direction of the circular line (4) through a switching means (8).
