Abstract
An industrial textile, such as a papermaking fabric, including a plurality of pre-crimped thermoplastic components. The pre-crimped components include dimensioned indentations that are complementary in size and shape to the components with which they are assembled. Methods of manufacture of the components and assembly of the textiles are also provided.
Claims20
An industrial textile comprising interconnected longitudinal and horizontal components, at least a portion of the longitudinal and/or horizontal components are formed of a polymeric material, the longitudinal components are pre-crimped so as to provide a plurality of bottom side indentations and top side indentations extending over an entire length thereof, the indentations formed by the pre-crimping are substantially complementary to a cross-sectional size of the horizontal components thereby allowing the horizontal components to be received and secured into position in the assembled fabric without further substantial deformation of the longitudinal components.
A method of manufacturing a textile fabric including the steps of:
- a) providing a plurality of longitudinal components;
- b) imparting a plurality of preformed, horizontally oriented bottom side indentations and top side indentations along the longitudinal components by pre-crimping extending over an entire length thereof, the indentations formed by the pre-crimping are substantially complementary to a cross-sectional size of the horizontal components thereby allowing the horizontal components to be received and secured into position in the assembled fabric;
- c) interlacing the longitudinal components with a plurality of horizontal components such that select horizontal components are received in and secured by the indentations without further substantial deformation of the longitudinal components.
