Abstract: A staple fiber batt of improved uniformity is made by the fibers falling onto a moving conveyor, skimming off the top of the batt by jets of air flowing across the top of the batt, which thereby determines the level of the batt, and redepositing the skimmed off fibers onto said batt. The batt can then be compacted for further processing.

Abstract: A machine for combing textile fibers prior to spinning, which operates to regroup the fibers in accordance with their length, is described. The machine operates to pull off tufts of fibers from a web or card sliver, to perform a preliminary combing of the fibers, and to deposit the tufts onto a conveyor with the fibers extending transverse the direction of advance and the ends of the fibers which were gripped in order to pull the tuft out of the web all aligned along the direction of advance of the conveyor. Subsequently the conveyor carries the tufts past a plurality of withdrawing devices which are successively nearer the conveyor and which operate to pull off first the longer fibers and subsequently successively shorter fibers. The fibers are subjected to a further combing operation as they are withdrawn from the conveyor.

Abstract: Direct-flame apparatus for drying coatings applied to the outer surface of metal cans. The apparatus includes a conveyor adapted to advance the cans in a continuous train through a tunnel having a series of direct-flame assemblies mounted therein, whereby each can in the course of its advance is progressively heated by the assemblies to cause the cans to emerge from the tunnel in a dried state. Each assembly is constituted by a gas-fed burner element and a hood placed thereover, the element emitting a sheet of flame which impinges on the coated surface and is flanked by curtains of air issuing from the hood at a velocity serving to confine the applied heat within a limited sector of the can and to prevent flashing of the coating despite the high temperature of the flame impinging thereon.

Abstract: This invention relates to a device for distributing textile fiber slivers inside collection boxes in spinning preparation machines, in particular in drawing frames. The device according to the invention comprises a plate rotating above the collection box and containing an eccentric outlet connected by a duct fixed to the plate to a substantially axial inlet which faces guide calendars for a sliver leaving a spinning preparation machine; the duct is formed by two tubular portions, which are partially inserted in one another and form a cylindrical passage external to the portion defining the duct inlet. In this manner the sliver is guided delicately by a cushion of air centrifuged towards the duct outlet and the friction due to rubbing of the sliver on the duct in proximity of the duct outlet is reduced to a minimum.

Abstract: A fiber distribution and depositing apparatus including a forming bell including front and back walls converging and convexly curved in the direction of flow, and side walls connected to the front and back walls to define an open-endedpassageway for fluid-entrained fibers leading from an inlet to an outlet end, said side walls diverging along straight lines in the direction of flow, the cross-sectional area of the passageway along the length thereof remaining substantially constant. The forming bell is disposed between a fiber transport means for directing gaseously-entrained fibers into the bell former inlet at a high velocity and a forming surface positioned adjacent to the outlet of the forming bell and movable along a predetermined direction of movement for receiving the fibers passing through the forming bell passageway.

Abstract: A system is disclosed wherein fibers are mounted on pallets for ease in handling and storage. The system uses the pallets to provide a continuous, uniform rate of fiber feed to other apparatus for subsequent fiber processing. A positioning system arranges pallets in end-to-end abutting relationship to provide the uniform rate of fiber feed generally desired for fiber processing. A plurality of vertically spaced horizontally disposed rotating augers engage the advancing face of fibers on a pallet to remove the bulk of fibers therefrom. The pallet surface is subsequently engaged by a pallet sweeper which removes any fibers not removed by the rotating augers. The loosened fibers are deposited on a transverse conveyor which overlies the pallet surface and moves the fibers transversely of the pallet unloading apparatus for delivery to the fiber processing apparatus.

Abstract: In order to provide effective cleaning of the opened fibrous material to be supplied to a spinning rotor, the fiber tuft projects into a removal opening opposite the opener roller, thereby permitting the impurities to be beaten out of the fibers, clamped between supply roller and supply table, by the clothing on the opener roller. They then fall directly into the removal opening without having to rebound from a wall.

Abstract: Apparatus for applying a synthetic resin coating of predetermined thickness to various articles of different sizes and shapes from a relatively rapidly deteriorating solution of the resin in which an intermittently driven conveyor housed in a controlled atmosphere and suspending different article groups of like articles at spaced locations along the conveyor successively moves the articles from a loading station first to a cleaning station at which the articles are subjected to the action of an ultrasonic cleaner, then to a destaticizing station, then to a coating station at which a dip tank is rapidly raised to immerse the articles in the solution and is lowered at a controlled rate to provide a coating of the required thickness in a single operation, and finally through a precuring zone in which the coating dries tack-free to the loading station at which the coated precured articles can be removed.

Abstract: In a spinning device of an open end spinning machine, a silver is fed to and passes through a feeding and opening device which opens the silver into individual fibers and feeds them into a rotary spinning chamber where they are collected and discharged as a finished yarn therefrom. In order to clean the fibers, when they pass through the feeding and opening device, dirt of the fibers is adapted to be thrown out by centrifugal force and leaves the fibers through a dirt discharge opening and enters through an intermediate duct into a dirt collecting chamber. The chamber is provided with an air inlet opening into the atmosphere and an air outlet connected with a source of negative pressure to produce a current of air which flows through the air inlet and outlet and by which the dirt collected in the chamber is continuously removed out of the chamber. A part of the air current tends to be directed through the intermediate duct to the dirt discharge opening.

Abstract: A seed cotton dryer system of the parallel flow tower type, having hollow vertically spaced horizontal shelves alternately extending from opposite sides of the tower to locations near but spaced from the opposite side to define a continuing zig-zag cotton flow path from the top to the bottom of the dryer through which the cotton travels impelled by conveying heated air. The hollow interior chambers of the shelves are supplied with heated air to heat the shelf surfaces and thereby facilitate drying, and the vertical spacing between shelves increases in one or more stages below the uppermost shelves providing for higher shelf velocity over the uppermost shelves. Means for recycling the cotton conveying air through the dryer and for monitoring the dew point of this conveying air to proportionately introduce fresh ambient air into the system and/or for monitoring cotton moisture content and automatically regulating heating of the drying air to regulate moisture content levels may be provided.

Abstract: A series of roller pairs in the drafting zone of sliver drafting apparatus have toothed or needlelike projections. The projections are spaced circumferentially and axially of the rollers so that projections of cooperating rollers either within a pair or between rollers of adjacent pairs are periodically interdigitated, as seen axially of the rollers, in spaced relationship as the rollers rotate at constant angular velocity. The rollers carry toothed wheels engageable for positive drive without backlash by a toothed belt. The upper rollers of the pairs are driven by a common endless loop belt and the lower rollers by a second belt. Each belt passes over a spring-loaded jockey roller which tensions the belt and which can be moved against the spring force in response to overloading tension on the belt caused by retardation of roller rotation in response to excessive fibres between a roller pair. Such movement of the jockey roller actuates a limit switch to shut off the belt drive motor.
