Abstract
An apparatus for drafting a continuous strand of staple fibers into a finer strand of the staple fibers and including a mechanism for supplying separated fibers suspended in a fluid and a rotating fiber chute receiving the fluid with the separated fibers axially and dispensing the fluid and the fibers radially. A collection belt with a porous portion is used for passing the fluid but holding back the fibers wherein the belt moves in a circular path around the chute and leaves the circular path to move the collected fibers thereon out of the circular path. A vacuum housing is positioned in close proximity to the collection belt and with an opening facing the collection belt for collection of the fluid.
Claims17
An apparatus for drafting a continuous strand of staple fibers into a finer strand of said staple fibers comprising:
- (a) a mechanism for supplying separated fibers suspended in a fluid;
- (b) a rotating fiber chute receiving said fluid with the separated fibers axially and dispensing said fluid and said fibers radially;
- (c) a collection belt with a porous portion of passing the fluid but holding back the fibers wherein the belt moves in a circular path around said chute and leaves said circular path to move the collected fibers thereon out of said circular path;
- (d) a vacuum housing in close proximity to the collection belt and with an opening facing said collection belt for collection of the said fluid.
An apparatus for blending staple fibers comprising:
- (a) a mechanism for supplying separated fibers suspended in a fluid;
- (b) a rotating fiber chute receiving said fluid with the separated fibers axially and dispensing said fluid and said fibers radially;
- (c) a collection belt with a porous portion for passing the fluid but holding back the fibers wherein the belt moves in a circular path around said chute and leaves said circular path to move the collected fibers thereon out of said circular path;
- (d) a vacuum housing in close proximity to the collection belt and with an opening facing said collection belt for collection of the said fluid.
The method of laying staple fibers, comprising the steps of:
- (a) providing a rotating fiber chute;
- (b) separating the fibers to be layed;
- (c) suspending the fibers in a fluid;
- (d) introducing the fluid-entrained fibers axially into the chute;
- (e) dispensing the fluid-entrained fibers radially from the fiber chute;
- (f) depositing the fluid-entrained fibers dispensed from the fiber chute onto an open, cylindrically shaped collection belt;
- and
- (g) continuously removing the fibers from the collection belt.
A method of drafting a continuous strand of staple fibers into a finer strand of staple fibers comprising the steps of first separating the fibers from a fluid and then laying the fibers with a rotating fiber chute onto an open, cylindrically shaped collection belt and then removing said fibers continuously from said collection belt.
The method for blending staple fibers comprising the steps of first separating the fibers from a fluid and then laying the fibers with a rotating fiber chute onto an open, cylindrically shaped collection belt and then removing said fibers continuously from said collection belt.
A method of drafting a continuous primary strand of staple fibers into a blended and evened-out secondary strand of staple fibers with a rotating fiber chute onto an open,
- cylindrically shaped collection belt by distributing said fibers of said primary strand over a perimeter of said collection belt and then removing said secondary strand continuously from said collection tape.
