Embodiment Construction

[0028] figure 1 The bar needle device 1 shown has a carrier 2 on which a number of bar needles 3 are arranged with the required stitch length. Each bar pin 3 is seated in a holder 4 , for example inserted in a hole in the tip of the holder 4 . Each holder 4 has two displacement drives 5, in figure 1 Only the displacement drive of the outer holder 4 of the two displacement drives can be seen. A displacement drive of the same type is arranged on the opposite side of the holder 4 .

[0029] The displacement drive 5 is designed in a known manner as piezoceramic bodies, which, when charged with a predetermined voltage, actuate the displacement of the holder 4 . This displacement causes the bar needles to move in one displacement direction. The displacement direction is the direction along which all the bar needles 3 of a bar needle device 1 are sequentially arranged.

[0030] The actuation of the displacement drives 5 of all the holders 4 of the bar needle device 1 takes place...

Abstract

The insert needle assembly includes a support (2), and several guide needles (3) arranged on the support. Each needle is provided with an offset drive (5), and a drive unit (6) is electrically connected with the offset drive. The drive unit is detachably connected to the support and to the offset drive by the spring contacts including a contact surface (33) on which the drive unit is formed. The guide needle is pivotably connected to the drive unit by the mechanical abutment (25). An independent claim is included for jacquard guide bar.

Description

technical field [0001] The invention relates to a bar needle device for a jacquard bar, which is provided with a carrier on which a plurality of bar needles are arranged, wherein each The bar needles are all equipped with at least one displacement drive; a driver device that is electrically connected to the displacement drive. [0002] Furthermore, the invention relates to a jacquard bar which is provided with a bar body and at least one such bar needle device. Background technique [0003] Such a bar needle device for a jacquard bar and such a jacquard bar have been published, for example, in DE 196 13 385 C2. Here, a plurality of bar needles are fixed on one holder. The holder is fastened to a segment, which in turn is fastened to the bar body. The segments have contacts, which are designed in the form of plug contacts or snap contacts, which can be brought into contact with the conductors of the bus, which are arranged on the bars. Contact is achieved when the segment...
