Embodiment Construction

[0066] figure 1 A part of the cross-section of the measuring roll 1 is shown. The measuring roll 1 here consists of a material 3 with a low coefficient of thermal expansion. Furthermore, the outer surface 5 of the measuring roll 1 is coated with a surface coating 4 . Grooves 8 are formed in the outer surface 5 . But as an alternative or in addition to the groove 8, it is also possible to form a hole 9 (such as image 3 shown) and / or bulbous bumps 18 (as Figure 4 shown).

[0067] The surface coating 4 here only partially covers the peaks between the two grooves 8 . Therefore, only the effective surface which is in contact with the composite fiber 6 is coated. It is also conceivable that the grooves 8 are completely coated with the surface coating 4 .

[0068] In addition, the grooves 8 also have an opening angle 11 . Two adjacent grooves 8 each have a distance 12 in the circumferential direction. Likewise, the grooves 8 have a groove depth 13 and a groove width 14 . ...

Abstract

The invention relates to a measuring roller for a device for measuring a fiber composite (2), in particular on a draw frame, a carding engine or a comber, made of a material of low thermal expansion (3) and having a surface coating (4), whereas the measuring roller (1) features a shell surface (5) for damping a fiber composite (6) along with a rotary axis (7). In accordance with the invention, the shell surface (5) of the measuring roller (1) features a structure forming an air buffer, made of grooves (8), boreholes (9) and / or spherical projections (18).

Description

technical field [0001] The invention relates to a measuring roll for a device for measuring composite fibers, in particular on a draw frame, a cashmere machine or a combing machine, which measuring roll consists of a material with low thermal expansion and has a surface coating , wherein the measuring roller has an outer cover surface for clamping the composite fiber and an axis of rotation. Furthermore, the invention relates to a device for measuring composite fibers, which has two rotatably mounted measuring rolls with a jacket, wherein the axes of rotation of the measuring rolls are aligned parallel to one another and the composite fibers can be guided through Between the outer surfaces of the measuring rolls, the device also includes a pressing device, by means of which the distance between the measuring rolls can be varied and thus a pressure can be exerted on the composite fibers surrounded by the measuring rolls. Background technique [0002] Measuring systems with s...
