Abstract
Abstract A soft non-marring carpet type support for articles while being heated into a softened condition consisting of either an intermittent or a continuous line of fine fiberglass fibers to accommodate either a flat or uneven surface in contact with the flexible tips, the support being so gentle and so distributed so as not to leave any impression on the articles softened surface. The support transmits a minimum of heat or cold by conduction, is transparent to infrared radiation across its thickness and also at the same time transmits infrared radiation through the length of its optical fibers.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
90 words
The method of heating an article by infrared radiation without harm to or any marring of the surface of said article comprising the steps of; supporting said article on the upper resilient tip ends of a myriad of vertically disposed tufts of heat resistant fibers bonded together at their lower tip ends into a rigid support; passing said radiation upwardly alongside of said fibers as well as; transmitting infrared rays internally through said fibers from their said lower tip ends to their said upper tip ends and to said article.
Claim 2
Independent Claim
90 words
The method of heating an article by infrared radiation without harm to or any marring of the surface of said article comprising the steps of; supporting said article on the upper resilient tip ends of a myriad of vertically disposed tufts of heat resistant fibers bonded together at their lower tip ends into a rigid support; passing said radiation upwardly alongside of said fibers as well as; transmitting infrared rays internally through said fibers from their said lower tip ends to their said upper tip ends and to said article.
Claim 3
Independent Claim
83 words
The method of heating an article by infrared radiation without harm to or any marring of the surface of said article comprising the steps of; supporting said article on the upper resilient tip ends of a myriad of vertically disposed tufts of heat resistant fibers bonded together at their lower tip ends into a rigid support; passing said radiation upwardly alongside of said fibers to said article and; wherein said fibers and said bonding are comprised of material transparent to said infrared radiation.
Claim 4
Independent Claim
83 words
The method of heating an article by infrared radiation without harm to or any marring of the surface of said article comprising the steps of; supporting said article on the upper resilient tip ends of a myriad of vertically disposed tufts of heat resistant fibers bonded together at their lower tip ends into a rigid support; passing said radiation upwardly alongside of said fibers to said article and; wherein said fibers and said bonding are comprised of material transparent to said infrared radiation.
Claim 5
Dependent Claim
24 words
The method according to claim 1 further comprising, the addition of a flow of convectional air along with said infrared radiation to said article.
Claim 6
Dependent Claim
24 words
The method according to claim 2 further comprising, the addition of a flow of convectional air along with said infrared radiation to said article.
