Abstract
The apparatus comprises at least one movable member (1) for the reception of the thread, a coupling arrangement (2) and a winding (3) which produces a magnetic field and is intended to produce different polarities in the coupling arrangement through which the magnetic flux passes and to bring the coupling arrangement into engagement with the member. The member (1) consists of magnetic or non-magnetic material and the coupling arrangement (2) of ferromagnetic material. The apparatus ensures a reliable coupling at high rhythm.
Claims9
An apparatus for selecting a thread in a textile machine, comprising a least one reciprocating member for picking up the thread and formed of one of magnetic material and non-magnetic material;
- coupling means including a bendable holding element displaceable in and out of engagement with the picking-up member, and a rigid element formed of a ferro-magnetic material;
- and means for producing a magnetic field which provides for bending of the holding element toward the picking-up member,
- wherein the picking-up member and the holding element have complementary, engageable each other sections,
- wherein the rigid element has a section located between the holding element and the picking-up member and extending in a direction opposite a direction in which a free end of the holding element extends, the section of the rigid element projecting beyond the free end of the holding element for limiting deflection of the holding element in a direction toward the picking-up member and for keeping the free end of the holding element at a distance from the picking-up member, and
- wherein the holding element and the rigid element have different polarities when subjected to action of the magnetic field.
