Abstract: A lubricating device for the revolving flat arrangement of a carding machine having two chains arranged at the sides of the card and engaging ends of the revolving flats. The chains move in a loop and are guided by stationary guides at least in the area of the card cylinder and slide surfaces of the flats slide along these guides. At least one lubricant container is provided at each side of the revolving flat arrangement and is responsible for the dosed lubrication of the sliding surfaces. A rotatable transfer element associated with the appropriate lubricant container comes into contact with the lubricant and the sliding surfaces and is driven from the appropriate chain via a gear wheel.

Abstract: A travelling flat bar includes a head, an opening in the head, a coupling element received in the opening and arranged for attaching the flat bar to a flat-moving chain and a securing (locking) arrangement for readily releasably retaining the coupling element in the opening. The locking arrangement cooperates with the coupling element for form-lockingly retaining the coupling element in the opening.

Abstract: A card wherein at least the pre-carding zone, located between the licker-in and the revolving flats is subdivided into a multiplicity of angular ranges with respect to the axis of the main cylinder, all of which have a unified angular extension or an integral multiple of this unified angular extension. In this zone, or in several of these zones on both sides of the main cylinder there are exchangeable fastening plates, lying opposite to each other in pairs, which can be fitted to the card shells, whereby the angular extension of the fastening plates around the axis of the main cylinder corresponds to the unified angular extension or to an integral multiple of this angular extension.

Abstract: A travelling flats assembly for a carding machine comprises two end rollers; an endless flexible belt trained about the end rollers for a circulating travel, and a plurality of clothed flat bars arranged to be entrained by the endless flexible belt for circulating travel therewith. Each flat bar has a head forming a longitudinal end of the flat bar. There are further provided a stationary slide guide extending between the end rollers along the lower flight of the endless belt and slidably engaging and supporting the flat bars when entrained for travel by the lower flight; and a form-fitting connection for coupling the head of each flat bar to the outwardly-oriented face of the endless belt.

Abstract: A revolving flat arrangement for a carding machine is characterized in that a suction tube with a suction opening is arranged within the loop at the deflection position from the card cylinder to the cleaning device and/or at the deflection position before the card cylinder. Fibers and particles of contamination which are carried by the flats and which reach the interior of the loop are sucked out through the suction tube.

Abstract: A top bar for carding machines formed from an elongated hollow cold drawn annealed profile. The annealing relieves any stresses developed in the profile during the cold drawing and a dimensionally stable top bar results therefrom.

Abstract: A carding engine comprises a carding cylinder (1) rotatable between bends (2a) at each side of the carding engine. A series of flats (20) are provided, each flat having opposite end sections, the flats being movable over an arc of the cylinder surface. Each bend comprises a stationary section (2a) and a plurality of rollers (9, 13, 14) each mounted on the stationary section for rotation about axes parallel to the cylinder axis. The rollers are located such that the radially outermost parts thereof relative to the cylinder form a support path substantially co-axial with the cylinder, the rollers forming a support for the end sections of the flats as they travel over the arc of the cylinder surface.

Abstract: A movable flat assembly for a carding engine. Each of a plurality of flat bars is connected at each end thereof to a chain at the respective side of the carding engine. Each chain comprises a plurality of connected units, each having coupling means for connection to the next adjacent unit and a carrier detachably connected to the flat bar. A support wheel is rotatably mounted on the carrier and is in rolling engagement with the bend at the respective side of the carding engine. Each side wheel has an axis of rotation parallel to the longitudinal mid plane of the respective flat bar and spaced therefrom by a distance that is no less than half the width of the flat bar.

Abstract: An arrangement for driving the traveling flats of a carding machine. A drive gear is readily releasably secured to the carding machine at one end of the flats for driving the flats in one revolving direction and, for driving the flats in another revolving direction, the drive gear is removed from the one end of the flats and readily releasably secured at the other end of the flats.

Abstract: A revolving flats arrangement for carding operation, and which is provided with a drive, guide and deflection element. Flats on both ends slide on guides, and are constructed so as to avoid the use of a flats chain. A driving element pushes ahead the flats in the region of a deflecting roller. Of the two deflecting rollers that are provided, one is used as a driving element. The driving element has engaging members 8, shaped as sprocket portions, and the flats can be pressed against the sliding guide by a belt or an elastic element. The flats are directed along a predetermined path by the sliding guide, and they form on the side facing the card cylinder, at one location, a gap which is associated with a vacuuming device. The clothing of the flats is located on the side facing from the card clothing, and is cleaned by an axially movable cleaning device.

Abstract: A card clothing clipped top comprised of a rigid base with a longitudinal groove extending lengthwise adjacent each side thereof and a pair of clips for attaching the top to a flat in a card clothing machine. Each clip has a curved upper portion which engages one of the grooves in the base of the top and a lower portion adapted to engage the bottom surface of the flat. An intermediate portion of the clip connects the upper and lower portions thereof and is provided with a plurality of inwardly extending tabs for engaging recesses in the bottom surface of the base.In manufacturing the clipped top, recesses are formed in the bottom surface of the base along the sides thereof. The curved upper portion of each clip is then engaged in one of the grooves and a plurality of tabs may be punched out of the intermediate portion and forced inwardly into engagement with the recesses to firmly secure the clips to the base.

Abstract: A flat section is positioned above a cylinder of a flat carding machine to accomplish a carding action therebetween. The flat section comprises a pair of endless chains supported for rotation in spaced relationship with each other, and a number of flat bars bridged between the paired chains so that they are arranged parallel to each other with clearances therebetween. One end of each flat bar is connected to a connected portion of one chain at which adjacent chain links are connected together and the other end of each flat bar is similarly connected to a corresponding connected portion of the other chain. Between each adjacent pair of flat bars is positioned a closing member, the opposite ends thereof being connected between the adjacent connected portions of the paired chains so that a longitudinal center axis of each closing member coincides with that of the associated clearance in all positions thereof with respect to the direction of rotation of the chains.

Abstract: A carding method in which the rotary flats of a carding machine are driven intermittently so that each time the flats are driven only a portion (1/6 to 1/4) of the flats opposed to the cylinder of the machine are replaced by fresh flats, thereby decreasing the amount of good fibers in the waste, particularly when carding synthetic fibers.The carding machine is provided with a solenoid clutch in the drive mechanism for the rotary flats and the flat cleaning means, and with a timer for controlling the clutch so that the flats can be intermittently driven at desired drive and stop intervals. For carding polyester fiber, the drive interval may be enough to replace one-fifth of the flats opposed to the cylinder of the machine with fresh flats, and the stop interval may be as much as sixty minutes.
