Abstract
Abstract A method for flocking a wire garment hanger in which electrostatically-charged fibrous flock particles are applied to an adhesive film on a portion of the hanger and the hanger is immediately heated to set the adhesive while the fibers remain radially oriented on the wire. The invention also contemplates blowing air sequentially on various portions of the surface of a bed of flock to cause the fibers to become suspended in air above the bed, through which suspension the hangers are passed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
152 words
A method for distributing and charging a flock material within an enclosure in order to apply said material to an electrically charged, adhesive coated coat hanger suspended in said enclosure comprising the steps of: a. providing an enclosure containing a mass of flock material fibers with a mass surface and electrode means for imparting an electrostatic charge of a first polarity to said fibers, said hanger being suspended above the mass surface and being provided with a charge of opposite polarity, b. directing a plurality of separate air streams intermittently for short time periods against the mass of flock material to lift fibers from the mass, entrain them in the air and carry them past the electrode means for imparting the charge of said fibers, thereby at least partially filling the space above said mass with charged fibers of the first polarity, and c. depositing the fibers on the oppositely charged hanger.
Claim 2
Independent Claim
152 words
A method for distributing and charging a flock material within an enclosure in order to apply said material to an electrically charged, adhesive coated coat hanger suspended in said enclosure comprising the steps of: a. providing an enclosure containing a mass of flock material fibers with a mass surface and electrode means for imparting an electrostatic charge of a first polarity to said fibers, said hanger being suspended above the mass surface and being provided with a charge of opposite polarity, b. directing a plurality of separate air streams intermittently for short time periods against the mass of flock material to lift fibers from the mass, entrain them in the air and carry them past the electrode means for imparting the charge of said fibers, thereby at least partially filling the space above said mass with charged fibers of the first polarity, and c. depositing the fibers on the oppositely charged hanger.
Claim 3
Dependent Claim
118 words
Apparatus for distributing and charging a flock material for coating said material on a surface of a coat hanger within said apparatus comprising, in combination: an enclosure having at least one opening for access by the hanger and a lower portion for receipt of a mass of flock material defining a mass surface; an electrode above the mass within the enclosure for imparting an electrostatic charge to fibers of said flock material; a plurality of air stream discharge means directed at said mass; and means for intermittently operating separate ones of said air stream discharge means for short periods of time to dislodge fibers from the mass to be entrained and carried in the air within the enclosure.
Claim 4
Dependent Claim
118 words
Apparatus for distributing and charging a flock material for coating said material on a surface of a coat hanger within said apparatus comprising, in combination: an enclosure having at least one opening for access by the hanger and a lower portion for receipt of a mass of flock material defining a mass surface; an electrode above the mass within the enclosure for imparting an electrostatic charge to fibers of said flock material; a plurality of air stream discharge means directed at said mass; and means for intermittently operating separate ones of said air stream discharge means for short periods of time to dislodge fibers from the mass to be entrained and carried in the air within the enclosure.
Claim 5
Independent Claim
109 words
A method for distributing and charging a flock material within an enclosure comprising the steps of: a. providing an enclosed space containing a mass of flock material fibers with a mass surface and electrode means for imparting an electrostatic charge of a first polarity to said fibers, and b. directing a plurality of separate air streams intermittently for short time periods against the mass of flock material to lift fibers from the mass, entrain them in the air and carry them past the electrode means for imparting the charge to said fibers, thereby at least partially filling the space above said mass with charged fibers of the first polarity.
Claim 6
Independent Claim
109 words
A method for distributing and charging a flock material within an enclosure comprising the steps of: a. providing an enclosed space containing a mass of flock material fibers with a mass surface and electrode means for imparting an electrostatic charge of a first polarity to said fibers, and b. directing a plurality of separate air streams intermittently for short time periods against the mass of flock material to lift fibers from the mass, entrain them in the air and carry them past the electrode means for imparting the charge to said fibers, thereby at least partially filling the space above said mass with charged fibers of the first polarity.
Claim 7
Dependent Claim
32 words
The method of claim 3 including the step of selectively operating opposed sources for said air streams intermittently so that different areas of said mass surface are acted upon at differed times.
Claim 8
Dependent Claim
117 words
Apparatus for distributing and charging a flock material for coating said material on a surface of an article within said apparatus comprising, in combination: an enclosure having at least one opening for access by the article and a lower portion for receipt of a mass of flock material defining a mass surface; an electrode above the mass within the enclosure for imparting an electrostatic charge to fibers of said flock material a plurality of air stream discharge means directed at said mass; and means for intermittently operating separate ones of said air stream discharge means for short periods of time to dislodge fibers from the mass to be entrained and carried in the air within the enclosure.
Claim 9
Dependent Claim
117 words
Apparatus for distributing and charging a flock material for coating said material on a surface of an article within said apparatus comprising, in combination: an enclosure having at least one opening for access by the article and a lower portion for receipt of a mass of flock material defining a mass surface; an electrode above the mass within the enclosure for imparting an electrostatic charge to fibers of said flock material a plurality of air stream discharge means directed at said mass; and means for intermittently operating separate ones of said air stream discharge means for short periods of time to dislodge fibers from the mass to be entrained and carried in the air within the enclosure.
Claim 10
Dependent Claim
24 words
The apparatus of claim 5 including means for charging said article within the enclosure with a polarity distinct from the charge imparted to fibers.
Claim 11
Dependent Claim
28 words
The apparatus of claim 5 including entrance vestibules for the opening for access to the enclosure, said vestibules serving to reduce escape of flock fibers from the enclosure.
