Abstract: A process for producing a fiberous batt by contacting fibers with particles of a copolymer of vinyl chloride and a diester of a vinyl unsaturated dicarboxylic acid.

Abstract: A process for contacting a moving fibrous web with a powder. The process comprises the steps of:I. passing a mixture of powder and air through the moving fibrous web;II. reversing the direction of movement of the fibrous web; and thenIII. passing a mixture of powder and air through the moving fibrous web in a direction opposite to that of Step I.An apparatus comprising an air-tight enclosure; means for maintaining subatmospheric pressure within the enclosure; means for passing a fibrous web through the enclosure; and means within the enclosure for passing a mixture of powder and air through the moving fibrous web.

Abstract: A process for producing a bonded laminated flexible structure by forming a thin web of fibers and then contacting the web with particles of a copolymer of vinyl chloride and vinylidene chloride and contacting the batt with a sheet of cellular material; subsequently heating the unbonded structure and further compressing the unbonded structure to form the bonded laminated flexible structure.

Abstract: In a cotton packaging system including a press section, transfer section, strapping section, bagging section and shrink section in longitudinal alignment, a cotton bale is formed by successive compression of overlapping cotton layers and is thereafter tied and bagged. The press section includes a vertically movable lower platen and stationary upper platens each presenting transient compression and conveyor surfaces that are oscillated during bale formation.

Abstract: Apparatus for the formation and feeding of a cotton batt including a cotton retention chamber in which a first conveyor conveys cotton in a generally lateral direction toward a batt exit opening in a chamber and a second conveyor of the endless belt type with a lower drive roll conveys cotton away from the opening in an upward direction generally transverse to the lateral direction to establish a rotating batt supply body in the chamber. A rotatable stripper disposed between the front end of the first conveyor and the lower drive roll of the second conveyor forms the exit opening between the stripper and the front end of the first conveyor, and strips a batt from the supply body.
