Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
97 words
The process of preparing a molded cushioning structure which comprises the steps of: a. shredding or otherwise subdividing pneumacel batting into particles of substantially single-fiber dimensions, b. mixing 1-50 parts by weight of the subdivided pneumacel batting of step (a) with 99-50 parts by weight of shredded elastomeric foam, c. wetting the resulting mixture with from 5-50 parts by weight of elastomeric binder progenitor, and d. curing the mixture resulting from steps (a) through (c) under conditions which result in conversion of the progenitor into an elastomeric adhesive, thereby bonding the mixture into a unitary elastomeric structure.
