Abstract
Abstract A garment finishing system adapted to provide dewrinkling of garments is described in which the garment is conveyed through a radiant heat energy zone which is effective to rapidly heat the garment and cause the fabric fibers to revert to their natural wrinkle-free condition. In a preferred embodiment of the invention, the heating elements comprise a bank of infrared heating elements disposed on opposite sides of a processing tunnel through which garments are continuously conveyed.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
77 words
A process for dewrinkling a wrinkled fabric garment without chemically altering same by supporting said garment in loose free-hanging condition and subjecting said garment to radiant heat energy along substantially its entire surface area to rapidly raise the temperature of said garment to a predetermined level of at least 200-300*F and below the level at which the fabric of said garment is burned or otherwise damaged, thereby to restore the fabric fibers to their natural wrinkle-free condition.
Claim 2
Dependent Claim
77 words
A process for dewrinkling a wrinkled fabric garment without chemically altering same by supporting said garment in loose free-hanging condition and subjecting said garment to radiant heat energy along substantially its entire surface area to rapidly raise the temperature of said garment to a predetermined level of at least 200-300*F and below the level at which the fabric of said garment is burned or otherwise damaged, thereby to restore the fabric fibers to their natural wrinkle-free condition.
Claim 3
Dependent Claim
16 words
The process of claim 1, in which said radiant heat energy is in the infrared range.
Claim 4
Dependent Claim
20 words
The process of claim 1, wherein said fabric is subjected to said radiant heat energy for less than 15 seconds.
Claim 5
Dependent Claim
59 words
A process for dewrinkling fabric garments comprising: hanging said garment on a hanger in loose free-hanging condition; moving said garment along a processing conveyor line while thus hung on said hanger; and while so moved subjecting said garment to radiant heat energy; thereby to rapidly heat said garment to restore the fabric fibers thereof to their natural wrinkle-free condition.
Claim 6
Dependent Claim
59 words
A process for dewrinkling fabric garments comprising: hanging said garment on a hanger in loose free-hanging condition; moving said garment along a processing conveyor line while thus hung on said hanger; and while so moved subjecting said garment to radiant heat energy; thereby to rapidly heat said garment to restore the fabric fibers thereof to their natural wrinkle-free condition.
Claim 7
Dependent Claim
21 words
The process of claim 4, in which said garment is subjected to said radiant heat energy for less than 15 seconds.
Claim 8
Dependent Claim
16 words
The process of claim 4, in which said radiant heat energy is in the infrared range.
Claim 9
Independent Claim
111 words
An apparatus for dewrinkling garments, comprising a narrow tunnel having side walls, conveyor means extending in a closed loop around one of said side walls through said tunnel, hanger mounting means mounted in spaced relationship along said conveyor means and adapted to mount hangers thereon, said conveyor means being effective to move said hanger mounting means through said tunnel, and radiative heating means along said side walls of said tunnel effective when activated to radiate intense heat energy into said tunnel, the intensity of said radiation dropping sharply above the level corresponding to the top of a garment when said garment is mounted on a hanger mounted on said mounting means.
Claim 10
Independent Claim
111 words
