Abstract
A thread guiding eye, which may be made from case-hardened or rust-proof steel, is embedded in a heddle moulded from plastic. The embedding is effected by injection-moulding the plastic around the thread guiding eye. The thread guiding eye may have an essentially crescent-shaped profile, its edges being embedded in the plastic in order to ensure a smooth and uninterrupted transition. The longitudinal parts and/or the region of the thread guiding eye are at least approximately oval in cross-section. A heddle of this type combines the advantages of a metal heddle because of the reduced wear of the thread guiding eye and those of a non-metallic heddle because of its low weight.
Claims8
A heddle comprising:
- a plastics material portion formed of a plastics material;
- a warp thread guiding eye inserted into said plastics material portion;
- said thread guiding eye possesses a substantially crescent-shaped cross-sectional configuration;
- said thread guiding eye being formed of a material which is harder than the plastics material of said plastics material portion;
- said thread guiding eye being embedded in the plastics material of the plastics material portion;
- said thread guiding eye being partially surrounded by the plastics material of said plastics material portion;
- said thread guiding eye having outer edges which are molded around and interengaged by said plastics material of said plastics material portion;
- and
- said thread guiding eye having an inner surface which forms a smooth transition to the plastics material portion.
