According to the invention, in order to be able to access the product data for the feed spools (4.1-4.6) when processing the yarns in the processing stations (1.1, 1.2, 1.3), the label on the feed spools takes the form of an RFID tag (5.1-5.6), wherein at least one RFID antenna (6.1-6.6) connected to a read unit (7) is allocated to the feed stations (3.1-3.6) for each tier.

The invention relates to a method and a device for producing a composite thread (13) from several individual threads (5.1, 5.2). The individual threads (5.1, 5.2) are held as supply spools (2.1, 2.2) in several supply stations (1.1, 1.2), pulled out in parallel, and combined to form the composite thread (13). The composite thread (13) is wound in a winding station (9) to produce an end spool (10). In order to make allocation and product tracking possible with a large number of supply stations, each of the supply spools (2.1, 2.2) features a separate RFID tag (4.1, 4.2) having an individual identification. The end spool (10) also has a separate RFID tag (4.3) having an individual identification, wherein the identifications of the supply spools (2.1, 2.2) are combined with the identification of the end spool (10) using a process control system (11).

Method and device for monitoring a texturing process
A method for monitoring a texturing process for producing crimped threads is presented, in which a thread tension is measured continuously on the textured thread and in which the thread tension measuring signals are captured and analyzed continuously, at least in one time interval, characterized in that a sequence of the thread tension measuring signals occurring in the time interval is analyzed with a machine learning program for the early diagnosis of one of a plurality of fault sources.

The invention relates to a bobbin housing for receiving a thread bobbin, having a hollow cylindrical housing body (1). The housing body (1) can be placed onto a bobbin spindle (8). In order to radially fix the housing body (1) on the circumference of a bobbin spindle (8), according to the invention, a fixing element (3) is arranged on at least one front end (2.1) of the housing body, which fixing element is elastically deformable in order to radially clamp the housing body (1) on the circumference of the bobbin spindle (8).
The invention relates to a spool spindle for winding multiple threads to form spools, comprising a projecting spool mandrel (2) for receiving multiple hollow-cylindrical spool tubes (3.1 - 3.4). The spool tubes (3.1 - 3.4) can be placed after one another onto the spool mandrel (2) and they can be axially fixed relative to a tube stop (4) around the circumference of the spool mandrel (2) via a clamping means (5). With a plurality of spool tubes (3.1 - 3.4), in order to obtain a secure hold to the circumference of the spool mandrel (2), each of the spool tubes (3.1 - 3.4) has a fixing element (7) at at least one end (6.1, 6.2), which is designed such that it can be elastically deformed in order to form a radial tensioning of the spool tube (3.1 - 3.4) on the circumference of the spool mandrel (2).
