Embodiment Construction

[0022] figure 1 A bar 1 in the form of a jacquard guide bar is schematically shown with a main body 2 which can be moved back and forth in the direction of the double arrow 3 . Arranged on the main body 2 is a section 4 with a plurality of knitting tools 5 in the form of guide needles. Each braiding tool 5 can be changed from figure 1 The neutral position shown in is moved toward the left stop 7 or toward the right stop 8 . The left stop 7 of a weaving tool 5 can be the right stop 8 of an adjacent weaving tool 5 .

[0023] When the bar 1 moves to the right with a stitch pitch during operation, but at the same time the bending converter 6 moves the knitting tool 5 to the left stop 7, then when the knitting tool 5 is configured as a yarn guiding needle, the yarn guiding needle The position of the guide ring 9 relative to the knitting needles not shown in detail does not change, so that the thread guided by the relevant guide needle does not form a mesh. The mode of operation...

Abstract

The invention relates to a method for maintaining a warp knitting machine, in particular to a method for maintaining a warp knitting machine having at least one guide bar (1) which has a piezoelectric bending transducer (6) to which a knitting tool (5) is fastened. The purpose of the present invention is to achieve high productivity in a warp knitting machine. For this purpose, it is provided that at least one electrical characteristic variable of the bending transducer (6) in the installed state is repeatedly determined and the characteristic variable is compared with at least one predefined limit value.

Description

technical field [0001] The invention relates to a method for servicing a warp knitting machine with at least one bar having piezoelectric bending transducers on which a knitting tool is fastened. Background technique [0002] As a result of aging and faults of the piezoelectric bending transducers during the production of knitted fabrics, thread guide defects or even crashes can occur during the course of time, which can lead to costly repairs. In this case, the warp knitting machine must be stopped unplanned and the corresponding bending converter must be replaced. This leads to an undesired production stop. Contents of the invention [0003] The invention is based on the task of achieving high productivity of warp knitting machines. [0004] This object is solved by means of a method of the type mentioned at the outset by repeatedly determining at least one electrical characteristic variable of the bending transducer in the installed state and comparing said characteri...
