ABSTRACT:
In the event of an interruption of the weaving process and in the case of weaving-technical operations, such as tabby weaving and unraveling, a trailing of warp thread bobbins and thus a trailing of warp threads which are withdrawn from the bobbins and form a warp thread family, cannot be avoided without significant expenditures. The trailing results in a so-called trailing length in the thread family which, unless it is correspondingly taken up and correspondingly released during the new start of the weaving process, results in an overstretching of the warp thread family during a starting operation of the bobbins. This disadvantage is avoided by deflecting the thread family within a feeding stand, in the event of a weaving stop, in a controlled manner from a reference plane into at least one defined position. At the new start of the weaving process, the deflection is eliminated in a controlled manner.
