发明名称 Shoe insole of a solid crystalline polymer
摘要 Heat softened polydienic sheets, such as transpolyisoprene or polychloroprene, are usefully mounted in rolls, the layers being separated by powders or granules such as salt to prevent cohesion, and the salt is preferably dusted off as used, or the sheet is passed through a warm water bath which will remove the salt and warm it and softening to an applying state useful for many purposes. It can be shaped as an in-sole for shoes and upon softening will accept the shape of the wearer's foot greatly improving the comfort; or as breast plates, athletic supporters, knee guards, head guards such as a helmet, ear guards or ear supports which may carry sound transfer means, i.e., such as headphones or a hearing aid; or it may be used as a bandage and for which purpose it can be reinforced by a long fiber and the comfort of the plastic bandage can be modified as by having perforations filled with fiber to transmit moisture from side to side.
