A secondary conveyor arrangement at the fabric entrance end of the frame is operative to temporarily remove each succeeding fabric support rod from the conveyor chains and, after a selected dwell time, to replace each removed rod onto the conveyor chains to control the festooning accumulation of the fabric on the support rods.

Abstract: A method and apparatus for finding and feeding a yarn end to be taken up in a textile winder in which bobbins in an upright disposition on individual tube support members are advanced sequentially to a winding position. A detector determines whether yarn is being unwound from the bobbin the winding position. If the detector detects that no yarn is being unwound, a yarn finding device locates with suction the yarn end on the bobbin in the ready position next succeeding the bobbin in the winding position. The finding of the yarn end is assisted by an air blowing device. A yarn feeding device feeds the yarn end to a yarn joiner to be joined to the trailing yarn end from a take-up yarn package, or places the yarn end on an empty take-up package tube. The yarn finding device employs an open end yarn end receiving portion, which applies suction to the upstanding end of the bobbin in the ready position.

Abstract: A pallet for transporting a textile cop or tube in a textile machine transport system accommodates tubes of differing inside diameters by providing at least three independently radially positionable support elements spaced circumferentially about a tube-support spindle and extending parallel to the longitudinal axis of the spindle and at least one resilient element acting radially outwardly on the support elements. The support elements are formed as fins that extend through slots in the spindle and are acted upon by torsion bars springs which spring-load adjacent fins in alternation. When textile yarn tubes are mounted on the spindles, the retaining force of the spindle increases steadily and attains its maximum once the tube is fully mounted.

Abstract: The present invention relates to an improved heat transfer device, such as the heat exchanger included in a system for cooling and conditioning air in a textile mill, the system having an air washer and the heat exchanger operating to cool water to be used in the air washer. Water is circulated through a chilling basin where it is cooled by a refrigeration system having evaporator panels in the basin, and the water flows through the basin from a supply inlet to a discharge outlet. Bubbler tubes discharge streams of air bubbles so that the air bubbles flow along the evaporator panels in close proximity thereto. Preferably, the streams of air bubbles are discharged from the bubbler tubes under pressure supplied by an air blower, with a manifold and connecting pipes supplying the pressurized air to the bubbler tubes. The bubbler tubes are preferably spaced from the outlet so that air bubbles do not enter the discharge outlet.
