Embodiment Construction

[0029] The previous forming fabric 2 was woven to a limited length, and then its ends were sewn to each other so that it formed a loop structure. The forming fabric 2 is then stretched between two rollers 3 , 4 arranged at a distance from each other, one of which is movably guided in such a way that the forming fabric 2 acquires a specific longitudinal tension. At least one of the rollers 3, 4 is mechanically driven in a clockwise direction. Driven by the drive system, the forming fabric 2 moves at a predetermined speed in the direction of the arrow A, while the rollers 3, 4 perform a rotational movement in the directions of the arrows B, C. It will be appreciated that the rollers 3, 4 are supported in a device frame (not described in more detail) in which the drive system is also housed.

[0030] The forming fabric 2 is manufactured to a finite length and is converted to the endless form shown by seams connecting the ends. In this embodiment, the forming fabric 2 consists o...

Abstract

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.

Description

technical field [0001] The present invention relates to a forming fabric for use in the web forming section of a paper machine, the forming fabric having or comprising a planar configuration of the fabric in which crossing yarns are joined to each other at crossing points and in order to improve Intrinsic stability in which the yarns are fused to each other at this intersection point. The invention also relates to a method for the manufacture of such a forming fabric, in which the planar configuration of the fabric is made of yarns which intersect and join each other at points of intersection, and where the yarns then pass through Heated to the melting point to fuse with each other. Finally, the invention also relates to a device for producing such a forming fabric. Background technique [0002] The forming fabric is a long, wide strip circulating in the first section of the paper machine (called the web forming section), which forms the planar upper part. At the upper st...
