Abstract: A mounting apparatus for a textile machine, especially a card, comprising support means maintaining a spacing between the textile machine and a foundation and a pneumatic cleaning device having blow- and suction openings arranged at least beneath the textile machine, and air channels blow communicating with pressure-and suction connections. The air channels which are constructed with respect to their flow properties or characteristics independent of the support means, are arranged in hollow spaces of the support means.

Abstract: Waste from a textile machine is removed by providing an air channel having top, side and bottom walls. In the area where the waste settles, the top wall of the air channel is formed by one or more shutters movable between closed and opened positions. When the shutters are opened, waste which has accumulated thereon when closed or which comes directly from the machine, falls into the air channel. The shutters are then closed and an air current is produced in the air channel by suitable means to convey the waste away.

Abstract: An air circulating system individual to a card machine is provided for use with a manifold apparatus for pneumatically cleaning about the carding machine.

Abstract: 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.

Abstract: A combination web cover and suction chamber define a crush roll plenum which communicates with and extends forwardly from the doffer plenum of a suction cleaning system for carding machines. It includes a suction opening closely spaced from the top crush roll and its scraper blade to continuously pick up accumulations of lint taken from the crush roll by the scraper blade. Intermittent blasts of compressed air are directed toward the scraper blade to purge it of accumulations of foreign matter which is blown into the continuous suction current.

Abstract: 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.

An air manifold having a plurality of spaced discharge nozzles is connected to the air pressure stabilizing chamber and is adapted to discharge a blanket of air beneath the machine.

Abstract: A card head for supplying pile fibers to a knitting machine is disclosed herein along with a method for using same. Precarded, pre cut fibers in sliver form are presented to a fluted roll in proximity to a highly polished nose guide. Sliver is fed therethrough to a clothed main cylinder rotating at a higher speed than the fluted roll to separate cut fibers from the sliver. Flats or the like are secured around a portion of the main cylinder and cooperate with the main cylinder in proper alignment of fibers floating thereon. A doffer roll is positioned adjacent the end of the flats, barely out of contact with the card clothing and rotating at a higher speed than the main cylinder. Teeth on the doffer thus remove the fibers from the main cylinder and properly present same to knitting needles passing thereacross. The card head is provided with cover plates to control air flow therethrough which assists in floating of the fibers and proper operation thereof.
