Embodiment Construction

[0090] Hereinafter, preferred embodiments are described in detail with reference to the accompanying drawings.

[0091] figure 1 A cross-section of a sanding belt 1 according to an embodiment is shown. figure 1 The different layers shown in show the abrasive belt 1 at different stages of the abrasive belt manufacturing process. It can be deduced from the first stage that the textile fabric 2 of the sanding belt 1 comprises a plurality of interconnected fabric threads 20 . Preferably, the textile fabric 2 has the form of a knitted textile fabric which can be produced, for example, by warp knitting on a fabric production machine. In a second stage, the textile fabric 2 is physically fixed by applying an impregnation 30 . In the third stage, the impregnated textile fabric 2 has been coated with a coating 40 . Further, abrasive material or grit 50 has been selectively applied by using a suitable hemming system. Thus, a continuous abrasive zone 60 is formed in which the abrasi...

Abstract

An abrasive belt is provided which comprises a textile fabric being formed of interconnected yarns, and a coherent abrasive area formed on one side of the textile fabric, wherein the abrasive belt further comprises a plurality of regularly distributed openings in the form of through holes. The abrasive belt allows for a homogenous distribution of the abrasive material and thus an even sanding finish as well as for an appropriate dust removal and appropriate mechanical properties.

Description

technical field [0001] The invention relates to abrasive articles in the form of abrasive belts, belt abrasive articles and corresponding conversion forms. Background technique [0002] Abrasive belts belong to the class of abrasive products that are widely used in hand-held and stationary equipment and different installations of various designs, where the advantage lies in the possibility of using a continuous and uniform grinding area for metals, paints, plastics and wood as well as Grinding, sanding, finishing or polishing of painted surfaces, etc. [0003] The backing of abrasive belts is usually paper or fabric and should meet certain requirements regarding their mechanical properties and functionality. It is necessary to keep the longitudinal elongation at a low level, and the strength in the transverse direction should satisfy the actual product application. [0004] The application of abrasive belts is in most cases associated with excessive dust formation, and a r...
