Embodiment Construction

[0013] Figure 1a , 1b Showing a side view and a cross-sectional view respectively, the serrated wire 1 of the invention comprises an integral elongated base region 2 (tooth base) and an adjoining edge region 3 (tooth blade). The tooth 4 is formed by cutting at the tooth plate 3, and the tooth has a tooth front 5, a tooth back 6 and two sides 7a, 7b (cf. Figure 1b ). There is a tooth gap 8 between the tooth back 6 and the tooth front 5 of two teeth 4 arranged one behind the other. This tooth 4, ie the tooth flank 5, consists of two parts, the first part 5 of the tooth tip 9 1 With a positive working angle α, the working angle α (rake angle) refers to the convexly curved first portion 5 of the tooth tip 9 1 The angle between the tangent of the wire and the vertical axis of the wire base (the bottom surface of the tooth base 2). Located at the tooth tip 9 and the first part 5 of the tooth flank 5 (tooth front) 1 with the second part 5 2 The part between the transition zon...

Abstract

A saw-tooth clothing for rollers and/or cylinders of flat cards or roller cards has an elongate foot region and an adjoining tooth region (blade) in which teeth have been formed by cutting, with a tooth front a tooth back and two side flanks, wherein between the tooth back and the tooth front of two adjacent teeth there is a gullet and the teeth consist of at least two portions, with a first portion, forming a technologically effective region. In order to provide a clothing that retains a high level of aggressiveness over its lifetime, the first portion of the tooth front is convex or approximately convex in the direction of movement of the clothing.

Description

Technical field: [0001] The invention relates to an all-steel sawtooth clothing for the rollers and / or cylinders of a flat card or roller card, with a long bottom region (tooth base) and an adjoining tooth region (tooth plate), Where a tooth is formed by cutting, the tooth has a tooth front, a tooth back and two sides, wherein there is a tooth gap between the tooth back and the tooth front of two teeth arranged one after the other, and the tooth comprises at least two parts, located at The first part of the tooth tip has a positive or at least slightly vertical working angle (face angle), and the part between the tooth tip and the transition zone between the first part and the second part constitutes a technically active area. Background technique: [0002] Cylinder clothings of flat or roller cards are worn during production. The sharp tip becomes blunt and the front part of the tooth is worn away. The wear condition of the front face of the tooth increases sharply upward...
