Problems solved by technology

Although the T-400 fibers are a type of corespun yarn, the equipment used to make corespun yarns is only suitable for Textile of T-400 fiber
[0008] Another problem inherent in the known devices is that they are not suitable for handling spools with large dimensions

Embodiment Construction

[0022] figure 1 A front view of a first embodiment of the device 1 according to the invention is shown. figure 2 shows the basis figure 1 Example enlarged detail view. image 3 shows the basis figure 1 side view of the device. Figure 4 shows the basis figure 2 The front view of the embodiment.

[0023] The device 1 comprises two pairs of unwinding cylinders 2.1, 2.2 for transporting core wire spools (bobbins) 3.1, 3.2 and for unwinding core wire (thread) 10 from the bobbins 3.1, 3.2. The difference with the equipment known in the prior art is that the equipment shown here is suitable for handling and processing larger bobbins 3, the length of this bobbin 3 is, for example, in the range of about 90mm-150mm and the diameter is about 100mm-150mm. 300mm. Other dimensions are also possible based on the field of application. Spacers 4 are arranged between the spools 3 to avoid mutual influence between the spools during operation. The unrolling cylinders 2.1, 2.2 are arra...

Abstract

The invention is directed to a device (1) for making a core yarn. The device comprises a first and a second pair of driven unrolling cylinders (2.1, 2.2). The first and the second pair of unrolling cylinders are arranged in horizontal (Y) direction behind and spaced a distanced apart from each other. Each is suitable to receive a bobbin (3.1, 3.2) of core filament. Per bobbin of core filament a first and a second deflection roller are arranged to deflect a core filament unrolled from the bobbin of core filament twice before it is entered into the spinning process of a spindle thereby reducing oscillation within the core filament.

Description

field of invention [0001] The invention relates to an apparatus and a method for manufacturing core yarns as described in the preceding patent claims. Background of the invention [0002] Apparatus for producing core yarns have been known since many years and are mainly aimed at the production of yarns with elastic core yarns. [0003] US Patents US2024156 and US2210884 are assigned to the United States Rubber Company and were published on December 17, 1935 and August 13, 1940, respectively. Both publications are directed to methods for making elastic yarns. The method describes how the core yarn is guided into the ring spinning process for the core yarn before the delivery rollers of the drawing unit and the covering of textile fibers are spun. [0004] FR1 449645 of Les Filatures du Srtel Felix Watine et FiIs was published on May 6, 1966 and discloses a device for the manufacture of core yarns. The core wire spools are arranged on two parallel unwinding cylinders. The ...
