DEVICE FOR PRODUCTION OF NONWOVEN MATERIALS Russian patent published in 1994 - IPC

FIELD: devices for production of nonwoven materials. SUBSTANCE: nonwoven material is produced from solutions or melts of polymers in electric field. Device consists of insulating cab, vertical belt conveyer with endless flexible fabric installed in the middle of cab, fiber-forming members installed on both sides of conveyer, mechanism for rolling out of carrying base rolling-on of finished material. Since the moment of carrying base arrival at conveyer, when it is secured between loading roller and conveyer belt, and up to rolling-on of finished material into roll from conveyer belt, having horizontal section located between lower shaft of conveyer and rolling-on mechanism, the material is kept on conveyer belt. Presence of considerable electrostatic force keeping carrying base on belt and tight contact of layers in roll of finished material provides for absence of shrinkage of carrying base and finished material. EFFECT: higher efficiency. 2 dwg
