Abstract

See full text

An elastic web of material has a multiplicity of stems extending from at least one side of the web. The web includes a first continuous layer of elastic material having a first side and a second side and a second layer of material. The second layer of material has a first side which faces the first side of the first layer and a second side from which the stems extend. The first and second layers of material are joined together. The second layer of material can be formed of thermoplastic material or melt processable polymeric material. The first and second layers of material are melt formed. They are joined by coextrusion or lamination to form a multiple layer sheet on which a multiplicity of stems are formed on at least the second layer by a process such as embossing the stems into the heated web using a patterned roll or mold.
