A truck carrying plural rows of vertically placed empty bobbins is conveyed to one end of the machine base of a flyer frame, the empty bobbins of the first row are taken out of the truck and conveyed to an empty bobbin supply device on the machine base, the truck is moved a predetermined distance by an intermittent feed unit, and fresh full yarn packages from the flyer frame already placed on a conveyor are transferred by a full yarn package transfer device to said truck at the positions from which the empty bobbins were removed. The operation of taking empty bobbins from the truck and supplying them to the empty bobbin supplying device on the machine base and the operation of transferring the full yarn packages to said truck are performed in an alternate fashion.

Cleaning device for preventing discharge of fly from a card into the atmosphere of a carding room by an air stream emerging from spaces between a plurality of flat bars. A resilient sealing member is disposed in each space between two adjacent flat bars in such a manner that two free side portions of the resilient sealing member are always urged against to each rib of the above-mentioned two adjacent flat bars. Each sealing member is held by a link member of the link chains which carry the flat bars, each flat bar riding on two spaced curved bars. A cover plate is rigidly mounted on each curved bar in such a way that the cover forms a duct with the above-mentioned flat bars moving along the working passage facing the cylindrical surface of the main cylinder of the card and with the above-mentioned resilient sealing members. Consequently such ducts are formed at the two sides of the card. At least one discharge pipe is connected to each duct so as to discharge the aforementioned fly from the card.

In a high production card, a taker-in undercasing without slits or apertures is disposed beneath a taker-in roller of a card and a suction device is disposed above the taker-in roller. A taker-in cover is mounted atop the taker-in roller and defines therebetween a sealed space in communication with the suction device, which suction device controls the air pressure in said space between the taker-in roller and the taker-in undercasing, so that impurities such as trash are mainly removed from the supplied fibers at a free space below the taker-in roller formed at a position upstream from the taker-in undercasing, and short fibers are separated from successive fibers mainly by the action of the suction device.

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.

In a bale plucking machine wherein a fiber bale is reciprocally displaced between a pair of displacement terminals by a pair of conveyer means disposed with an intervening space therebetween and fiber tufts are continuously plucked from the fiber bale by a plucking roller when the fiber bale passes over the plucking roller, a method and device for supplying a fresh fiber bale on the conveyer means. When the thickness of the processing fiber bale has been reduced to a predetermined limit, the processing fiber bale is displaced to a waiting position formed on an extended portion of one of the conveyer means outside the terminal of the reciprocal displacement thereof, and the conveyer means are stopped. Thereafter a fresh fiber bale is supplied onto the processing fiber bale reserved at the waiting position. During the above-mentioned supply motion, the driving of the conveyer means is again commenced.

An improved method and apparatus for plucking fiber tufts from a fiber bale held by a supporting frame which is reciprocally displaced along a carrying passage over a plucking roller. A pair of conveyer means are disposed with an intervened space therebetween and the plucking roller is disposed in the abovementioned intervened space. An auxiliary conveyer means is disposed at a position adjacently outside one of the conveyer means. These three conveyer means are arranged in an alignment. The supporting frame is capable of being reciprocally displaced by the conveyer means between displacing terminals on said conveyer means and is capable of being displaced to a waiting position on one of the conveyer means which is outside of the displacing terminal on that conveyer means and at a side of the auxiliary conveyer means. A door means of the supporting frame is opened during the displacing motion of the supporting frame to the waiting position, and then a fresh fiber bale reserved on the auxiliary conveyer means is supplied into the supporting frame, thereafter the supporting frame is displaced to the normal operational position thereof. A loading plate is mounted on the supporting frame so as to uniformly press the fiber bale during the bale plucking operation. All of the above-mentioned operations are carried out automatically.
