Method for producing thread connection at textile machine station and textile machine station

Abstract

The invention relates to a method for producing a splicing connection of an upper thread and a lower thread at a textile machine station and a corresponding textile machine station. The aim of the invention is to provide a method for producing a splicing connection of an upper thread and a lower thread at a textile machine station and a corresponding textile machine station in order to ensure a high splicing quality that remains unchanged and a reliable reproducibility of the splicing connection. In particular, the tension interruption during the yarn joining process is prevented. According tothe invention, the method comprises the following steps: supplying at least the upper thread and / or the lower thread to the thread joining unit and measuring the thread tension of at least the upperthread to be joined by means of a thread tension sensor prior to the thread connection, wherein subsequently a comparison of the measured thread tension with a predetermined limit value is carried out, in which at least one measure for reducing the upper thread tension, in particular for reducing the upper thread tension, is carried out when the limit value is exceeded, and finally which of the thread ends of the lower thread and the upper thread is connected when the measured thread tension is below the predetermined limit value.

Description

technical field [0001] The invention relates to a method for producing a splicing connection of an upper yarn and a lower yarn at a station of a textile machine, a corresponding station of a textile machine and a winding machine having at least one corresponding station. Background technique [0002] Various designs of methods for joining two yarn ends, in particular by means of yarn splicing, are known from the prior art. Thus, for example, in a winding machine the yarn is rewound from several smaller feed bobbins into large package cross-winding bobbins, where it is necessary to connect the already wound yarn, i.e. the top yarn, with the yarn from the new The yarn fed to the bobbin is the lower yarn. However, the methods of the prior art do not lead to a reliable and error-free connection of the two yarn ends in all cases, which usually results in an immediate break of the connecting yarn and at the same time the yarn ends have to be searched and connected again. In addi...

In this method, however, the incorrect connection of the two yarn ends also occurs periodically and the corresponding yarn immediately or subsequently splits at the connection point.
