Galette with shiny stripes

The invention relates to a godet in conveyor or Drafting units for synthetic threads, yarns, thread cables or the like. With a matt chrome-plated running surface and in the axial direction with bright chrome-plated strips of the same width according to patent application P 19 25 210.9.

Galettes are understood to be cylindrical rollers or cylinders that are driven to rotate about their axis of rotation, in particular In stretching or texturing devices, the threads, yarns, thread cables or the like looped around them are promoted.

Such godets are for reasons of mechanical stability mainly made of metals or metal alloys such as aluminum, copper, brass or steel. . *

On godets, where the running surface has been bright chrome-plated, is the adhesion of the yarn is relatively high, which is advantageous for the stretching of the reduction in the slip, but also for an increase in the frequency of breakage Capillary winder leads. Capillary winders arise from the fact that individual thread capillaries adhere to the godet in such a way that they

chen and separated from the rest of the capillary association of the thread the godet wrap until after a certain time the capillary are taken along by the thread association again without it being Thread breakage is coming. Such capillary winders lead to a considerable deterioration in the quality of the yarn. In later processing operations, they then often become very annoying because they wind up, for example, in thread guides, thread brakes, the needles of knitting machines or even on the reed of a loom. Therefore, before such processing operations, the lint monitor is switched on in the thread run Show capillary winder. The flaw must be removed from the thread and the thread knotted again, which requires a considerable amount of time.

In the case of godets with a matt chrome-plated running surface, these Capillary curlers avoided. But you have to accept the disadvantage that because of the increased slip, the full stretching is only achieved when the godet of the Threads, yarns, thread cords or the like. Was entangled frequently.

The object of the present invention is to design the running surface of a godet in such a way that full stretching is achieved with a slight looping of the godet and the mentioned capillary curlers are largely avoided *

In the main application, this task is carried out by a galette in Conveyor or drafting units for synthetic threads, yarns, thread cables or the like. With matt chrome-plated and in acialer direction salt bright chrome-plated strips of the same width of the running surface, in which two bright chrome-plated strips are arranged on opposite points of the circumference and the Angle between which the endpoints of the strips with each other connecting cutting circle diameter to a radian dimension of

Figure 1 shows the side view of such a godet according to the invention.

FIG. 2 shows a section perpendicular to the godet axis fc along the line AA in FIG.

In Figure 1 (1) is the matt chrome-plated running surface of the godet, - on the at the same time in the axial and tangential direction running gloss strips (2) are arranged helically on opposite points of the tread.

In the section along the line A-A of Figure 1, in the Figure 2 is shown, connect the cutting circle diameter (3) the end points (4) of the glossy strips (2) on the matt chrome-plated Tread (1) together to form the angle x.

FIG. 3 shows the side view of a godet according to the main application. The gloss trelves (2) on the Matt chrome-plated running surface (1) run here in the axial direction. A sectional view along the line A-A corresponds to this Section drawn in FIG. 2 along line A-A in FIG. 1.
