Forming fabric for a papermaking machine and method for manufucturing such a forming fabric

摘要

The filter (2) has a textile planar structure including longitudinal yarn (5) and transverse yarns (6, 7) that are engaged with each other at crossing points (14) and are fused with each other. The transverse yarns contain an additive that imparts the ability to absorb laser energy, where the transverse yarns are bicomponent yarns that include a core and a casing surrounding the core, and the additive is contained only in the casing. The transverse yarns are brought to a melting temperature at a surface by the absorbed laser energy. Independent claims are also included for the following: (1) a method for manufacturing a forming filter for use in a sheet-forming section of a paper machine (2) a device for manufacturing a forming filter.
