Definitions
- the invention relates to a control module for controlling the needles a knitting or knitting machine with a housing and at least one piezoelectric bending transducer arranged therein, wherein the bending transducer comprises a flat support body, which is at least on one side with a piezoelectric active layer and at a rear end is firmly connected to the housing.
- Such a control module is suitable for controlling the needles or stitch-forming elements of a textile machine, such as a knitting or knitting machine. This is particularly suitable Control module for use on a jacquard machine.
- a textile machine becomes the information whether a needle is forming a stitch is used or not, via a mechanical Obtained scan of the deflection of the bending transducer. Dependent a mesh is formed from the deflection of the bending transducer or not.
- a control module is known from US 3,961,501 A, at which the movable end or front end of the piezoelectric Bending converter with a guide part is by which one assigned for the elevation of each needle Depends on part of a knitting machine as it passes from the deflection of the bending transducer to an operative position is pressed or not.
- the operative position is the stroke of a corresponding cam with the help of the uplifted part, for which also the technical term Circuit board is used on the appropriate needle transfer.
- every single needle of the Knitting machine can be controlled separately.
- the positioning speed of known bending transducers is sufficient not out of a theoretically possible knitting speed to reach.
- control module described in US 3,961,501 A is in similarly also known from EP 0 210 790 A2. Also here a number of bending transducers are combined in the control module, in order to control the working speed of the Increase textile machine.
