Problems solved by technology

[0007] A disadvantage of the prior art is that there is insufficient control over the process of forming the corespun yarn, leading to inconsistent results in terms of quality
Furthermore, the devices known in the prior art do not provide the opportunity to influence the process itself on ring spinning machines with several spindles
Furthermore, the devices known from the prior art do not allow to arrange the spindles in a dense manner

Abstract

The invention relates to a device (1) and a method for producing a core yarn (9) on a ring spinning machine. The device (1) comprises: a first creel (10) which will be used to hold at least one spool of roving (8); a second creel (12) which will be used to hold the covered yarn (13) at least one spool; and a draft control device (15) adapted to adjust the draft of the covered yarn (13) before it enters the weaving process. Furthermore, the device (1) comprises a monitoring device (22) for monitoring the presence of the covering yarn (13) and, if the covering yarn (13) is absent, said monitoring device for interrupting the feeding of the roving (7) to the relevant Supply of drafting unit (2). The covered yarn (13) is introduced into the weaving process via an injector (27).

Description

technical field [0001] The invention relates to a device and a method for producing clad yarns on a ring spinning frame (ring spinning frame). Background technique [0002] Devices for producing core yarns on ring spinning machines are described in the prior art. Core yarns are manufactured as follows: Before the staple fiber sliver is spun into yarn, the staple fiber sliver is passed through a drawing unit in a ring spinning machine. A second yarn is added which will at least partially wrap the staple fibers. Different locations for adding fibers are known. [0003] US2013040523, nominally belonging to The Japan Wool Textile Co.Ltd., was published in February 2013. This application describes heat and flame resistant protective clothing fabrics formed from spun yarns. The spun yarn used to form the above fabric is a two-ply yarn prepared by twisting a first yarn of a homogeneously blended spun yarn covered by a second yarn on a ring spinning machine.
