ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an apparatus for selecting a thread in a textile machine and including a reciprocating member for picking up a thread, a holding element, a guide member, and means for producing a magnetic field acting on the holding element for displacing it in engagement with picking-up member.
2. Description of the Art
In the manufacture of textile structures, different threads are selected and/or moved for the patterning. In modern textile machines with high speeds of rotation the know apparatuses prove to be too complicated and/or too sluggish.
The invention is based on the object of improving an apparatus for the selection of a thread in a textile machine.
SUMMARY OF THE INVENTION
This and other objects of the present invention, which will become apparent hereinafter, are achieved by forming the guide member as a rigid element that limits the deflection of the holding element toward the picking-up member and prevents the free end of the holding member from engaging the picking-up member, and by generating a magnetic field such that it produces different polarities in the holding and rigid elements.
The advantages of the invention are to be seen essentially in the simple construction and the ensuring of a reliable coupling of the member and of the coupling arrangement and in the possibility of converting existing apparatuses.
