Abstract
An encapsulated shuttle grip for use in shuttles for holding bobbins in a properly aligned position during weaving. The grip includes a pair of opposed leaves which have opposed gripping jaws for receiving a butt end of a bobbin. Inner shank portions of the leaves are imbedded in a molded housing with the gripping jaws extending outwardly from the housing. The molded housing extends around the remote sides of the inner shank portions and in the space provided between the shank portions positively positioning the gripping jaws for receiving the butt end of the bobbin.
Claims4
An encapsulated shuttle grip for use in a shuttle for holding a bobbin in a properly aligned position during weaving, positioning rings carried on a butt end of said bobbin, said shuttle grip comprising:
- a pair of opposed rigid steel leaves having:
- (i) outer spaced apart steel gripping jaws for receiving a butt end of a bobbin,
- (ii) inner shank portions, and
- (iii) grooves provided on inner surfaces of said steel gripping jaws for receiving said rings of said bobbin,
- a molded housing,
- said inner shank portions being imbedded in said molded housing with said gripping jaw portions extending outwardly from said housing in a spaced apart relationship for receiving a bobbin head, said inner surfaces of said steel gripping jaws being free of said molded housing, and
- said molded housing extending on both sides of each leaf a sufficient distance toward said outer spaced apart steel jaws for positively and firmly holding said outer ends of said leaves in precise spaced apart relation maintaining the alignment of said leaves relative to each other as preset during molding said housing on said leaves.
An encapsulating shuttle grip for use in a shuttle for holding a bobbin by a butt end in a properly aligned position during weaving, said shuttle grip comprising:
- a pair of opposed leaves each having:
- (i) an outer gripping jaw portion for receiving a butt end of a bobbin,
- (ii) an inner shank portion,
- (iii) an arcuate intermediate portion joining said outer gripping jaw with said inner shank portion,
- a molded housing,
- said inner shank portions and said arcuate intermediate portions being embedded in said molded housing with said gripping jaw portions extending outwardly from said housing in a precise spaced apart relationship for receiving a bobbin head and firmly holding said butt end therebetween,
- inner surfaces of said steel gripping jaws being exposed for receiving said bobbin head, and
- said precise spaced apart relationship of said gripping jaw portion being preset during molding said housing around said leaves.
