Patent number: 5196258Abstract: The invention relates to a method for producing a vulcanizable composite material which can be dynamically stressed. The material is made of an elastomeric matrix having a reinforcement layer made of a textile fabric embedded therein. The fabric is prepared with an aqueous dispersion of synthetic resin and latex before being embedded in the elastomeric matrix and then dried. An adhesive interface coating is applied to the dried fabric with the coating being vulcanizable polar rubber present in an organic solution. The dried fabric provided with the adhesive interface coating is rubberized with a thin coating of rubber stock and embedded in the elastomeric matrix. An organic solution of toluene which contains chlorosulfonated polyethylene (CSM) as a vulcanizable polar rubber is used to apply the adhesive interface coating in order to produce a composite material which provides a good adhesion between the reinforcement layer and the elastomeric matrix even in the presence of high alternating flexural stresses.Type: GrantFiled: September 6, 1991Date of Patent: March 23, 1993Assignee: Continental AktiengesellschaftInventors: Michael Keller, Klaus Schreck, Siegfried Dietrich, Gerhard Thurow

Patent number: 4425111Abstract: The invention concerns expanding files. A flat strip of flexible material (12) is progressively folded longitudinally to form a U-shaped channel. A length of the material equivalent to the developed width of a gusset is drawn forward. A precut partition with glued tabs (113) is placed at the rear of the drawn forward section of material. A fold is formed by pushing the three edges of the channel inwardly. This sequence of operations is repeated to form a multiplicity of pockets, comprising a plurality of parallel partitions joined along three edges to constitute respective filing pockets by the flexible material which is concertina-folded to constitute respective gussets. This multiplicity of pockets may be sectioned to provide separate expanding files. The invention comprises the manufacturing method and the machine for implementing same.Type: GrantFiled: March 17, 1981Date of Patent: January 10, 1984Inventor: Andre Chazelas
